Let me clear up the most common misunderstanding I hear in clinic: sickle cell trait (SCT) is not a mild form of sickle cell disease (SCD). They are two different things, and most people with SCT live entirely normal lives.

Here is the simple version. Inside every red blood cell is a protein called hemoglobin — the part that carries oxygen from your lungs to every tissue in your body. The "build instructions" for hemoglobin come from genes you inherit, one from each parent. Sickle cell trait means you inherited one normal hemoglobin gene and one sickle hemoglobin gene. Sickle cell disease means you inherited two abnormal hemoglobin genes — one from each parent.

People with SCT are sometimes called "carriers." Their red cells contain mostly normal hemoglobin and a smaller amount of sickle hemoglobin, and under everyday conditions, those cells work just fine.

Who has SCT? SCT is most common among people whose ancestors come from Africa, the Mediterranean, the Middle East, and South Asia — but anyone can have it. About 1 in 12 Black or African American people in the U.S. carries the trait.

What does it mean for your family? This is the part that matters most. If both you and your partner have SCT (or another abnormal hemoglobin gene like HbC or beta-thalassemia trait), each child you have together has:

• a 1 in 4 (25%) chance of having sickle cell disease
• a 1 in 2 (50%) chance of having sickle cell trait
• a 1 in 4 (25%) chance of having neither

Knowing your status before you start a family is one of the most loving decisions you can make.

Are there health problems with SCT? Most people never have any. Rarely, SCT can play a role in problems like dehydration during intense exercise, blood in the urine, eye injury complications, or pain at high altitudes. The fix is awareness, hydration, and telling your healthcare provider you have SCT — especially before strenuous activity, surgery, or travel to altitude.

How do I find out? A simple blood test. Ask your provider, or contact the Sickle Cell Foundation of Arizona for a screening connection.

Knowing is power. Get tested. Tell your kids. Tell your partner. Then go live your life.

📄 Resource: CDC What You Should Know About Sickle Cell Trait.

If you remember nothing else from today, remember these five.

1. Sickle cell disease is inherited — both parents have to pass on a sickle gene. A child gets sickle cell disease (SCD) only when they inherit two sickle hemoglobin genes — one from each parent. A child who inherits just one sickle gene has sickle cell trait (SCT). If both parents have SCD or SCT, family planning conversations matter, and a genetic counselor can walk you through the math.

2. SCD is global. We tend to talk about sickle cell in the United States as a Black community condition, and the burden here is real — but SCD affects millions of people worldwide. It's most common among families whose ancestors come from sub-Saharan Africa, the Mediterranean, the Middle East, India, and parts of Central and South America. Sickle cell is a global story with a local face.

3. SCD can be cured for some patients. Bone marrow transplant has cured patients for decades, but it carries serious risks and requires a matched donor. Newer gene therapies were approved by the FDA in 2023 for patients aged 12 and up — they re-engineer the patient's own stem cells to make healthy hemoglobin. These are major breakthroughs. They're also expensive, complex, and best discussed with a SCD-specialist team to see if they're right for you.

4. Anemia is part of the picture — and it's treatable. In SCD, sickled red cells die early, so the body doesn't have enough to carry oxygen. That's anemia. It can get worse with infection or spleen problems. Blood transfusions, hydroxyurea, and newer SCD-specific medications all help manage the anemia and the broader disease.

5. People with SCD live long, full, meaningful lives. More than 95% of children born with SCD in the United States today live to adulthood. The keys are: regular check-ins with an SCD-savvy team, taking medications like hydroxyurea exactly as prescribed, preventing infections (handwashing, vaccines, prompt fever response), drinking 8–10 cups of water a day, and listening to your body.

Sickle cell is not a sentence. It's a condition you manage — and the science gets better every year.

One blood test. That's all it takes to know your sickle cell status — and the answer can change how you raise your kids, plan a pregnancy, train for a sport, or prepare for surgery.

What "sickle cell status" actually means. Your status tells you what kind of hemoglobin your red blood cells make. Most people make 100% normal hemoglobin (status: HbAA). Others carry a single sickle gene (sickle cell trait, HbAS) or a different hemoglobin variant (HbAC, HbA-β-thal). And some people have sickle cell disease itself — HbSS, HbSC, or HbS-β-thalassemia — which is a different, more serious condition.

You will not "feel" sickle cell trait in everyday life. The only way to know is to test.

Who should get screened?

• Every newborn in the United States is already screened for sickle cell as part of the newborn screening program. If you're a parent, ask your pediatrician for your child's results — they're in the chart.
• Adults of childbearing age, especially before starting a family. If your partner also has a hemoglobin variant, your child could inherit sickle cell disease.
• Anyone whose status was never confirmed. That includes adoptees, internationally born adults, and many people whose newborn screen is hard to track down.

The right test (and the wrong one). Ask your provider for:

• A Complete Blood Count (CBC) with Mean Corpuscular Volume (MCV) — flags anemia and certain hemoglobinopathies.
• Hemoglobin electrophoresis, HPLC, or DNA testing — these tell you exactly which hemoglobin types you make.

Avoid the sickle cell solubility test (sometimes called Sickledex). It can mislead — it doesn't distinguish trait from disease and shouldn't be used to determine status.

Where do I go? Your primary care provider, your local health clinic, or a community sickle cell organization. The Sickle Cell Disease Association of America (SCDAA) maintains a national directory: 1-800-421-8543.

Then what? Once you know your status, sit down with your provider — and, if there's a chance of trait or disease, a genetic counselor — to talk through what it means for you and the next generation.

You don't have to wonder. You can know.

When patients sit down with me to talk about starting a family, the genetics piece is the part that feels most overwhelming. Let me make it simple — through three families I've seen versions of in clinic.

Maria and Saanjh — both have sickle cell trait. They're newlyweds. Maria carries one sickle gene; Saanjh carries one sickle gene. With every pregnancy, the math shakes out the same way:

• 25% chance the baby has neither trait nor disease (HbAA — completely normal)
• 50% chance the baby has sickle cell trait (HbAS — like Mom and Dad)
• 25% chance the baby has sickle cell anemia (HbSS — full disease)

That last one is the conversation worth having. Genetic counseling, prenatal options, and early intervention plans all start here.

Kwame and Nancy — one has hemoglobin C trait, one has sickle cell trait. Their first child inherited two normal genes — perfectly healthy, no trait. With every future pregnancy, though, the odds reset:

• 25% chance of HbAA (no trait, no disease)
• 25% chance of sickle cell trait (HbAS)
• 25% chance of hemoglobin C trait (HbAC)
• 25% chance of HbSC disease — a form of sickle cell disease that can be milder than HbSS but still requires lifelong care.

Many families don't realize that sickle cell plus a different hemoglobin variant still produces disease. Hemoglobin C trait alone is silent — but paired with sickle, it becomes SCD.

Nia and Kiano — one has beta-thalassemia trait, one has sickle cell trait. With every pregnancy:

• 25% normal
• 25% sickle cell trait
• 25% beta-thalassemia trait
• 25% HbS beta-thalassemia — another form of sickle cell disease.

The takeaway across all three families: any combination of two abnormal hemoglobin genes can produce sickle cell disease. That's why "we tested for sickle cell and we're fine" sometimes isn't enough. A full hemoglobin panel — electrophoresis or HPLC — tells the complete story.

What to do if any of these stories sound like yours. Get screened. Bring the results to a genetic counselor. Walk through the options together. There is no wrong choice — there is only an informed one.

If you live with sickle cell disease (SCD), chances are your medicine cabinet has more than one prescription in it — pain medication, hydroxyurea, antibiotics, vaccines, maybe a newer SCD-specific drug. Each one has a job. Each one comes with risks. And each one only works if you and your team are on the same page.

Here are three habits I ask every SCD patient to build.

Habit 1 — Ask about benefits and risks before you start. Every medication does something good and risks doing something you don't want. Before you fill a new prescription, sit down with your provider or pharmacist and ask three questions: What is this medication supposed to do for me? What side effects should I watch for? What should I do if I notice one? Write the answers down. Stick them on your fridge. Use a notes app on your phone. The point is to take ownership.

Habit 2 — Take it exactly as prescribed. Right amount. Right time. Right way. This is where good intentions go to die. Common stumbles I see in clinic:

• Skipping doses on "good days" because you feel fine.
• Doubling up after a missed dose (don't — call your provider).
• Stopping early when symptoms ease.
• Sharing or substituting medications.

If something about your treatment plan isn't working — cost, schedule, side effects, transportation — tell your provider. A plan you can't follow isn't a plan; it's a wish. Your team can adjust.

Habit 3 — Report side effects. Every time. Side effects aren't a failure. They're information. Nausea, fatigue, mood changes, rash, easy bruising, change in appetite — anything new that started after a medication change is worth a phone call. Your provider can treat the side effect, lower the dose, or swap to a different medicine. They can't help if they don't know.

One more thing. Bring your full medication list — including over-the-counter pills, supplements, and herbal products — to every appointment. Some of those interact with SCD medications in ways the pharmacy bottle won't warn you about.

The goal isn't perfection. The goal is partnership.

A sickle cell pain crisis — what clinicians call a vaso-occlusive episode — comes on fast. It can feel like the bones themselves are on fire. The middle of a crisis is the worst possible time to be figuring out who to call, where to go, and what medication you usually get. The work happens before the pain.

Step 1 — Build an Individualized Pain Management Plan with your provider. This is a real document, signed off by your hematologist or SCD specialist. It contains:

• Your full name, date of birth, and contact info.
• Your provider's name and after-hours number.
• The medications and doses you've been prescribed for crises.
• Your typical home plan (heat, hydration, oral medication) and the threshold at which you escalate to in-person care.
• Any history of past treatments, complications, or specific medications that work for you.

Carry it on your phone. Print a paper copy. Leave one with whoever rides with you. Update it once a year.

Step 2 — Know your treatment options. Acute SCD pain is most often treated with opioids like oxycodone, hydrocodone, or morphine, but they aren't the only tool:

• Ketamine (in supervised settings) helps when opioids alone aren't cutting it.
• NSAIDs can layer in for inflammation, when not contraindicated.
• Non-medication approaches — guided relaxation, virtual reality, massage, TENS, yoga, music — work alongside medication, not instead of it. The science on these is real.

Step 3 — Know where to go. For many SCD patients, the emergency department is not the best first stop. Long waits, unfamiliar staff, and inconsistent treatment can extend a crisis. If your community has an SCD-specific day hospital or infusion center, that's the better destination — staff who know SCD, treatment protocols built for you, faster pain control.

If the ED is your only option, walk in with your pain plan in hand. It changes the conversation.

A final word on opioids. Yes, they have risks. Yes, they save lives in SCD pain crises. The two facts can both be true. Talk openly with your provider about how to use them effectively while protecting your long-term health.

Athletes — let's get this out of the way first. Sickle cell trait does not disqualify you from any sport. Olympic medalists, NFL Pro Bowlers, college All-Americans, and weekend warriors all carry SCT. What sets the safe ones apart isn't talent — it's awareness.

This blog is for you, the athlete. Whether you're a high schooler with a recently confirmed trait status, a college recruit, a CrossFit regular, or a recreational marathoner — this is your playbook.

Yes, you can play. Here's how to play smart.

1. Hydrate before you're thirsty. Thirst is a late warning. Pre-hydrate the night before a hard session. Sip during. Rehydrate after. Water is the baseline; an electrolyte drink helps in heat or long sessions. Skip pre-workouts with high caffeine and stimulants — they accelerate dehydration.

2. Acclimatize gradually. The two highest-risk windows for any athlete with SCT:

• The first 7–14 days of a new training program.
• The first 24–72 hours at higher altitude or in dramatically warmer weather.

Build intensity over time. Skip "max effort tests" early. The body adapts — give it the runway.

3. Pace yourself, even when the team is sprinting. Your job in conditioning is to compete with yourself. If a drill sets the entire team to "as hard as possible until you puke," that's the moment to set your own pace. The best coaches respect this; the great ones build it in for everyone.

4. Know the warning signs of exertional sickling:

• Muscle burning, weakness, or pain
• Cramps that don't behave like normal cramps
• Rapid breathing without wheezing
• Feeling overheated, can't cool down, sweating less than expected at rest
• Prolonged fatigue you can't shake

Stop. Tell someone. Sit down. Hydrate. Cool down. Get help. The thing that distinguishes exertional sickling from a sudden cardiac event is that you can usually still talk. Use that. Tell a coach, a trainer, a teammate.

5. Tell your coach and trainer your SCT status — but only when you're ready. You're not legally required to disclose, but disclosure unlocks better care. Tell trainers and team docs. They will protect your privacy.

6. Train with the basics in place:

• Get a physical before starting any new program.
• Don't train when you're sick.
• Limit alcohol and energy drinks the day before hard training.
• Sleep. Real sleep. Your body recovers there.

You weren't built fragile. You were built informed.

Acute pain is a fire alarm. Chronic pain is a different beast — pain that lasts most days for six months or longer. It rewires the nervous system. It bleeds into sleep, mood, work, and relationships. And it almost never responds to the same playbook as a vaso-occlusive crisis.

If you are living with chronic sickle cell pain, here is the bigger toolbox.

Medications that target chronic pain pathways:

• SNRIs (duloxetine, milnacipran) — antidepressants that also dampen pain signaling.
• Tricyclic antidepressants (amitriptyline, nortriptyline) — older but still effective, often at low doses.
• Gabapentinoids (gabapentin, pregabalin) — calm down nerve-related pain.
• NSAIDs (ibuprofen, naproxen) — for inflammatory layers, when kidneys allow.
• Opioids — yes, they have a role, but the role in chronic pain is more nuanced than in acute pain (more on this below).

Non-medication approaches that genuinely work:

• Cognitive behavioral therapy (CBT) — the most evidence-backed non-drug option for chronic pain. It doesn't tell you the pain is "in your head"; it teaches your nervous system new patterns.
• Acupuncture, massage, yoga, mindfulness — supportive, low-risk, and increasingly covered by insurance.
• Physical therapy — strengthens the body around the pain.
• Sleep hygiene — chronic pain wrecks sleep, and bad sleep amplifies pain. Treat both.

The opioid conversation, honestly. Long-Term Opioid Therapy (LTOT) is not the first answer for new chronic pain — try other options first. If you're already stable on LTOT and functioning well, work with your provider on the risks and benefits of staying. If you're on LTOT and not functioning well, the answer probably isn't more — it's a different plan altogether. None of this is a moral judgment. It's clinical evidence.

What I tell patients in clinic:

• Pick a "home base" provider who knows your full picture.
• Don't manage chronic pain alone. Bring a partner, a sibling, a friend into your appointments.
• Set goals beyond pain scores — work hours, walking distance, sleep hours, joyful days.
• Track flares so you and your provider can see patterns.

Chronic pain isn't who you are. It's a thing you carry. There are real tools that help you carry less.

Coaches, this one is for you. Roughly 1 in 12 Black or African American athletes in the United States carries sickle cell trait (SCT) — and many of them don't know it. The first thing I want every coach to hear is the most important: SCT does not keep anyone off the field. Athletes with sickle cell trait play youth football, varsity basketball, college track, and the Olympic Games. What changes is not their right to compete — it is the level of awareness on the sideline.

Here is the science in plain language. Sickle cell trait means a person carries one copy of the sickle hemoglobin gene. Under most conditions, their red blood cells behave normally. But under extreme heat, severe dehydration, sudden spikes in intensity, or rapid altitude change, those cells can briefly change shape and slow blood flow to working muscles. The result is a rare but real condition called exertional sickling, which can look like a heat cramp at first and escalate quickly.

So what's a coach's job? Build a program that protects every athlete and have a plan when something goes wrong.

Build it in:

• Start every preseason gradually. Resist the urge to "test toughness" with timed sprints in week one.
• Schedule water breaks like you schedule plays. Make hydration the default, not the reward.
• Adjust for heat, humidity, and altitude. Acclimate over 7–14 days.
• Cut high-caffeine pre-workouts. They mask fatigue and accelerate dehydration.
• Have a written Emergency Action Plan — and rehearse it once a year.

Spot the warning signs: Muscle burning or weakness, cramping, rapid breathing without wheezing, feeling overheated, prolonged fatigue. An athlete experiencing exertional sickling can usually still talk — that's what makes it different from a sudden cardiac event. Pull them out, cool them down, hydrate, and get medical eyes on them.

Never use exercise as punishment for an athlete in physical distress. Never push through "for toughness." And if an athlete has shared their SCT status with you, treat that information like the medical record it is — confidential, protected, and respected.

Coaches save lives every season just by paying attention. Let's keep doing that.

If you have sickle cell trait (SCT), most days look like everyone else's. But when you fly to a mountain town, hike a 14er, or train at altitude for the first time, your body experiences a real physical change — less oxygen in the air — and on rare occasions, that change can stress an organ you don't think about often: your spleen.

A quick refresher on the spleen. Your spleen sits in the upper left part of your abdomen, tucked behind the rib cage. It does three jobs: it makes immune cells that fight infection, it filters out worn-out red blood cells, and it stores blood. When the spleen loses blood flow, parts of it can die — that's called a splenic infarct.

SCT and splenic infarct. Splenic infarct is rare in the general population. It's still rare in people with SCT — but slightly more likely than in people without the trait, especially under three conditions: 1. High altitude — typically above 1,100 meters (around 3,600 feet, which includes Flagstaff, Denver, Albuquerque, Salt Lake City, and most ski areas). 2. Severe dehydration. 3. Very intense physical activity — especially before your body has acclimatized.

The warning signs:

• Sudden, persistent pain in the upper-left abdomen (sometimes radiating to the left shoulder)
• Chest pain when you breathe in
• Nausea
• Fever

If you experience these — especially at altitude — get medical attention. Tell the team you have SCT. If you're at high elevation and stable enough, ask about transport to a lower altitude.

Can I still fly? Can I still hike Sedona, Flagstaff, the Grand Canyon? Yes. Modern commercial airplanes are pressurized — flying is safe. Spending time and exercising at altitude is also safe with the right precautions:

• Hydrate aggressively — start the day before, continue throughout.
• Pace yourself. The first 24–48 hours at altitude is not the time for a personal best.
• Acclimatize. Spend a couple of low-effort days at altitude before strenuous activity.
• Don't ignore symptoms. Headache, dizziness, persistent abdominal pain — pause, rest, hydrate. Seek care if it doesn't pass.

For Arizona families especially: the elevation gain between Phoenix (1,100 ft) and Flagstaff (7,000 ft) is real. Plan for it. Pack water. Slow your first day.

You're not fragile. You're informed. There's a difference.

If your provider just prescribed a blood thinner, you probably have questions. Good. Blood thinners are powerful, lifesaving medicines — and they are also one of the most common causes of medication-related ER visits when patients aren't given good information. Let me give you good information.

What are blood thinners? The medical name is anticoagulant — anti meaning "against," coagulant meaning "clotting." Blood thinners don't actually thin your blood; they slow your body's ability to form clots. That's lifesaving when a clot in your leg (DVT) or lungs (PE) is the reason you're on the medication, but it also means bleeding is the main side effect to watch for.

Two big families:

• Warfarin (Coumadin) — the classic. Requires regular blood tests called INR to keep the dose right. Vitamin-K-rich foods (spinach, kale, broccoli) affect how it works — you don't need to avoid them, you just need to eat them consistently.
• Direct Oral Anticoagulants (DOACs) — newer drugs like apixaban, rivaroxaban, dabigatran. No INR monitoring required, fewer food interactions, but still serious.

The non-negotiable rules:

• Take it every day at the same time. Set a phone alarm.
• Never double up if you miss a dose. Call your provider.
• Tell every clinician you see — your dentist, your dermatologist, your pharmacist. Especially before any procedure.
• Avoid aspirin and aspirin-containing products unless your provider explicitly approves it. Same with most NSAIDs (Advil, Motrin), Pepto-Bismol, and many cold medicines. Bring the bottle to your pharmacist before you take it.
• Skip the alcohol.
• Talk to your provider before starting any supplement or herbal — garlic, ginkgo, green tea, multivitamins. They interact more than people realize.

Bleeding warning signs — call right away: Heavier-than-usual menstrual bleeding, red or brown urine, tarry stools, vomiting blood, coughing up blood, severe headache or stomach pain, big unexplained bruises, a cut that won't stop, dizziness or weakness. Any fall or head bump → ER, even if you feel fine.

Stay safe at home: Electric razor instead of a blade. Soft toothbrush. Gloves for yard work. Helmet for biking. Sturdy shoes. Don't trim corns or calluses yourself.

A blood thinner is a partnership between you and your provider. Show up. Take it seriously. You'll be fine.

If you have sickle cell disease (SCD), your risk of forming blood clots is higher than in the general population. That's a fact worth respecting — and a fact that should never run your life. Awareness keeps you safe.

Two clots, two emergencies.

Deep Vein Thrombosis (DVT) — a blood clot in a large vein, usually in the leg or arm. Warning signs:

• Swelling in one leg or arm
• Pain or tenderness without an injury
• Skin that's warm to the touch with swelling or pain
• Redness with swelling or pain

If a DVT goes untreated, the clot can break loose and travel to the lungs.

Pulmonary Embolism (PE) — a blood clot in the lung. This is a 911 emergency. Warning signs:

• Sudden, severe, unusual shortness of breath
• Sudden, severe, unusual chest pain
• Faster-than-normal or irregular heartbeat
• Coughing up blood

Don't wait. Don't drive yourself. Call 911 or get someone to take you to the closest ER immediately.

Risk factors you can do something about:

• Long periods of sitting still — long flights, long road trips, post-surgery, after a fracture. Move your ankles. Stand up every hour.
• Smoking — the most modifiable risk factor on this list.
• Estrogen-containing birth control or hormone replacement — talk to your provider; alternatives exist.
• Carrying extra weight — the conversation, not the lecture. Even small changes lower clot risk.
• Family history of clots — share it with your provider.

Other risk factors to know about:

• Cancer
• Hospitalization or surgery
• Pregnancy and the postpartum period
• Vein trauma

About the medications. Anticoagulants — also called blood thinners — are the standard treatment after a clot. The duration depends on what caused it:

• First clot from a temporary trigger (surgery, fracture, immobility) → typically 3–6 months.
• First clot with no clear trigger → often lifelong.
• Repeat clots with ongoing risk factors → lifelong.

The lifesaving benefits of these medicines almost always outweigh the risks. Just bring your full medication list to every appointment, and learn the bleeding warning signs (covered in our Blood Thinner 101 post).

Bottom line: know your warning signs, move your body, talk to your provider, and don't ignore swelling or shortness of breath.

An eye injury is always serious. If you have sickle cell trait (SCT), it's an emergency — even when it doesn't look like one. Here's why, and what to do.

The risk in plain language. A direct blow to the eye — a basketball, a stray elbow, an airbag, a fall — can cause bleeding inside the front part of the eye. That's called a hyphema. After a hyphema, pressure inside the eye can climb dangerously fast — that's called glaucoma post-hyphema, and it can damage the optic nerve and rob you of vision permanently if it isn't managed quickly.

People with sickle cell trait develop glaucoma post-hyphema more readily than people without the trait. The chemistry inside the eye after a bleed favors red cell sickling, which clogs the eye's natural drainage system, and pressure builds.

What to do — right now. 1. Go to the emergency room. Not urgent care. Not "I'll wait and see." The ER, today. 2. Tell every clinician you see that you have sickle cell trait. This affects which eye-pressure medications are safe for you — some standard glaucoma drugs make sickling worse and shouldn't be used. 3. Ask for an ophthalmologist — an eye specialist, not just an emergency room doc. The ER team can stabilize you, but eye trauma in SCT belongs in the hands of an ophthalmologist as fast as possible. 4. Do not bend over, don't strain, don't rub the eye. Keep your head elevated. Cover the eye with a rigid shield (not pressure) while you travel.

Warning signs that mean it's getting worse:

• Increasing eye pain
• Sensitivity to light getting worse
• Vision getting blurrier or darker
• Nausea or vomiting
• Severe headache around the eye

After the immediate crisis:

• You may be on bedrest for several days.
• You may need eye drops, oral medications, or in stubborn cases, surgery.
• You'll need follow-up appointments — keep every one of them. Glaucoma post-hyphema can rebound days after the original injury seems to be healing.

Prevention going forward:

• Wear protective eyewear in any sport with a ball, a stick, a puck, or fast bodies. Polycarbonate lenses are the standard.
• Tell coaches about your SCT status if you're an athlete (they don't need details, just enough to know how to respond if you take a hit).
• Carry a medical ID card that mentions your SCT — first responders can act faster.

Your eyesight is worth the inconvenience.

Your kidneys are quiet workers. They filter your blood every minute of every day, balance your fluids and minerals, manage your blood pressure, and even help your body make red blood cells. With sickle cell disease (SCD), they work harder than the average kidney — and over time, that wear and tear shows up.

Here's how to stay ahead of it.

Step 1 — The once-a-year urine test. The single most important kidney habit for SCD patients is an annual urine albumin test. Albumin is a protein that shouldn't be in your urine in any meaningful amount. When it shows up, it's often the earliest sign of kidney trouble — earlier than any symptom you'd feel. Catching it gives your provider time to start medications that protect your kidneys before damage compounds.

If you can't remember the last time you had your urine checked, that's the call you make this week.

Step 2 — Know the symptoms of worsening anemia. Anemia is part of SCD by definition. But when your kidneys start to slow down, anemia can get worse — sometimes silently. Tell your provider if you experience:

• Worsening fatigue
• General weakness
• Pale skin
• Cold hands and feet
• New dizziness
• Shortness of breath that's worse than your baseline

Your provider can prescribe medications that boost red cell production when kidney-related anemia is the driver.

Step 3 — Understand the long arc. Chronic Kidney Disease (CKD) means the kidneys are progressively losing function. CKD has stages — early stages are silent, later stages are not. End-stage kidney disease (ESKD) is when the kidneys can no longer keep you alive without dialysis or a transplant.

Patients with SCD who reach later kidney stages are often candidates for kidney transplant, and the data show people with SCD do well with transplant. It's a real option, not a last resort. Have the conversation early — well before you need it.

Daily habits that protect your kidneys:

• Hydrate consistently (8–10 cups of water a day, more in heat or activity)
• Take SCD medications as prescribed (especially hydroxyurea — it has kidney-protective effects)
• Manage blood pressure
• Limit NSAIDs (Advil, Motrin) without provider approval — they're hard on kidneys
• Don't smoke
• Treat infections promptly — UTIs hit harder in SCD

Your kidneys can't tell you when something's wrong. The lab can. Don't skip the urine test.

Lungs and sickle cell are tied tighter than most people realize. People with sickle cell disease (SCD) face higher rates of breathing problems and sleep-related disorders than the general population — and those two things often feed each other. Catching trouble early protects everything downstream: your heart, your energy, your brain, your quality of life.

Here's a checklist to bring to your next clinic visit. Check off anything you've experienced — even occasionally — in the last year.

Daytime breathing:

• [ ] Coughing or wheezing
• [ ] Shortness of breath
• [ ] Difficulty breathing during exercise
• [ ] Chest pain
• [ ] Low oxygen levels (hypoxemia)

Sleep:

• [ ] Loud snoring
• [ ] Feeling sleepy or drowsy during the day
• [ ] Waking up feeling unrested
• [ ] Early morning headaches
• [ ] Trouble focusing or thinking clearly

SCD-related red flags:

• [ ] Acute chest syndrome (any history)
• [ ] Blood clots in the lungs (PE)
• [ ] Stroke
• [ ] Frequent pain crises
• [ ] Recurring, prolonged erections (priapism)
• [ ] Bedwetting after age 10
• [ ] Congestive heart failure
• [ ] Fainting or dizziness

Why these matter — together. Each item on its own can have multiple causes. But for someone with SCD, certain combinations point your provider toward specific tests:

• Sleep study (polysomnography) if the sleep checklist lights up — sleep apnea is more common and more dangerous in SCD.
• Pulmonary function tests (PFTs) to measure how well your lungs move air, if the daytime breathing list is checked.
• Echocardiogram if cardiac symptoms appear.

Acute chest syndrome (ACS) deserves its own paragraph. ACS is a life-threatening complication of SCD that combines fever, chest pain, low oxygen, and a new finding on chest X-ray. It can come on fast — sometimes after a regular pain crisis. If you're hospitalized for pain and you start having chest pain, fever, or shortness of breath, tell your team immediately. Treatment works best when started early.

Daily lung-friendly habits:

• Hydrate — 8 to 10 cups of water a day.
• Don't smoke. If you smoke, ask for help quitting; SCD makes the damage worse.
• Avoid secondhand smoke and high-pollution exposures.
• Keep up with vaccines — flu, pneumonia, COVID. SCD changes the math on infection risk.
• Use your incentive spirometer if your provider gave you one.

Bring the checklist to your appointment. Don't edit it down. The picture only helps when it's complete.

Let me say this clearly because the misinformation has been loud: if you have sickle cell trait (SCT), you can donate blood. You can register as an organ donor. You can register as a tissue donor. In most cases your donation will go directly to saving a life.

I have heard the rumors — that SCT donors are turned away, that donation is unsafe for people with the trait, that it's not "worth signing up." None of that is true. Here are the facts.

Is donating blood safe for someone with SCT? Yes. There is no evidence that giving blood causes additional harm to a donor with sickle cell trait. The criteria that decide whether you can give blood (recent travel, medications, hemoglobin level, etc.) are about your overall medical history — not about whether you carry the sickle gene.

Then why do donation centers ask? Some centers have rules about which components of blood — whole blood, plasma, platelets, red cells — they'll collect from SCT donors. That's not a safety issue for you. It's a processing issue: not every center has the equipment to filter sickled cells out of certain blood products meant for patients who can't tolerate them (such as patients with sickle cell disease receiving transfusion).

The fix: call your local donation center before you go. Ask which blood products they accept from SCT donors. Many will take whole blood. Some will collect plasma. The Red Cross and AABB-affiliated centers can answer specifics.

Why your donation matters more than most. The community most affected by sickle cell disease is also the community most under-represented in the blood donor pool. Patients with SCD often need transfusions that are antigen-matched — and the closest matches almost always come from donors of similar ancestry. You giving blood may be the difference between a child finding a matched unit or not.

Organ and tissue donation. Yes — register. Don't disqualify yourself based on age, SCT status, or medical history. The transplant team evaluates suitability at the time of donation, taking the whole picture into account. Your "yes" on the registry is what makes the rest possible.

Where to start:

• Blood: Red Cross (redcrossblood.org), local hospital blood banks, community blood drives.
• Organ/tissue: registerme.org or your state DMV.
• SCFA Arizona can connect you to local opportunities.

Sickle cell trait isn't a barrier to generosity. It's a reason to lead with it.

Most people with sickle cell disease (SCD) will receive at least one blood transfusion in their lifetime. Some will receive many. Transfusion saves lives — and it's also a procedure that asks you to be an informed partner. Here are five steps that meaningfully change outcomes.

Step 1 — Share your full transfusion history. Tell every new provider how many transfusions you've had and whether you've ever reacted to one. Reactions can look like fever, severe pain, fatigue, or brown/red urine. If you've reacted in the past, your provider may discuss immunosuppressants to lower the chance your immune system attacks future donor blood.

Step 2 — Know your blood type. All of it. A standard "type and screen" looks at ABO and Rh. That's not enough for SCD. Ask for an extended red cell antigen profile — a more detailed map of the proteins on your red cells. This profile lives in your medical record and travels with you to every transfusion.

Step 3 — Request matched blood. Patients with SCD most commonly react to mismatches in the C/c, E/e, and K antigens. When you arrive for a transfusion, ask: "Is the donor blood matched for C/c, E/e, and K?" This single question prevents a meaningful share of transfusion reactions.

Step 4 — Track your iron. Every transfusion adds iron, and iron in excess deposits in your liver, heart, and endocrine organs — silently, until it causes damage. After 10 lifetime transfusions, you're in iron-overload territory. Two tests track this:

• Ferritin blood test — usually done first.
• Liver MRI (T2*) and cardiac MRI if ferritin is elevated (above 1,000) and you receive regular transfusions.

If iron is high, iron chelation medications can pull it out. They work — but only if you take them.

Step 5 — Ask about red cell exchange. For patients who need transfusions on a regular schedule (chronic transfusion therapy), an automated red cell exchange is often a better choice than a simple transfusion. Instead of just adding healthy blood on top of your sickled blood, the exchange machine removes sickled cells and replaces them with healthy donor cells. Result: a higher proportion of healthy hemoglobin and less iron loading over time.

Not every center offers exchange transfusion. If yours doesn't and you're chronically transfused, ask whether referral is an option.

You don't have to be a hematologist to advocate for safer transfusion. Three questions — "Extended antigen profile? C/c, E/e, K matched? Red cell exchange option?" — change everything.

If you ever look down and notice your urine is pink, bright red, or brown — pause. That's hematuria: blood in the urine. Sometimes it's so subtle you can only see it under a microscope; sometimes it's obvious. Either way, if you have sickle cell trait (SCT), it's worth a same-week appointment, not a wait-and-see.

Why the urgency? Most causes of hematuria are not serious — bladder infection, kidney stones, intense exercise, a recent injury. But blood in the urine can also be the first sign of something that is serious, including a rare but aggressive kidney cancer called renal medullary carcinoma, which is more common in people who carry sickle hemoglobin.

The point isn't to scare you. The point is: blood in the urine is a signal, and it deserves a real workup, not a shrug.

What might be happening:

• Dehydration or intense exercise — both can cause hematuria, especially in someone with SCT. The kidneys' inner workings (the medulla) operate in a low-oxygen environment that the sickle cell gene doesn't love.
• Urinary tract infection — usually with burning, frequency, urgency.
• Kidney stones — usually with severe flank pain.
• Trauma — a fall, a hit, a hard tackle.
• Renal medullary carcinoma — rare but real.

What to expect at the appointment: Your provider will ask about your history (exercise, hydration, infections, family history of kidney problems). They'll do:

• A urinalysis with microscopy (confirms the bleeding, looks for infection or cell casts).
• Imaging — typically a CT scan or MRI.
• Possibly a referral to a nephrologist (kidney specialist) or urologist (urinary tract specialist).

Don't accept "it's just your sickle cell trait" without a workup. Your provider should be able to explain why they ruled out other causes before landing on SCT as the explanation.

While you're waiting for the appointment:

• Drink water. A lot of it.
• Rest. Skip strenuous workouts until you're seen.
• Track it. Note the color, when it started, what you were doing.
• If pain, fever, or significant bleeding develops — go to the ER.

You don't get points for toughing this one out. Make the call.

Here's a quiet thing that catches a lot of people off guard. If you have sickle cell trait (SCT) and your doctor uses an A1C blood test to screen for or manage diabetes, the result might not be telling the truth.

What the A1C is supposed to do. The A1C measures your average blood sugar over roughly the past three months. It's used to:

• Diagnose type 2 diabetes
• Diagnose prediabetes (where blood sugar is high but not yet in the diabetes range)
• Monitor how well diabetes treatment is working

A normal A1C is below 5.7%. Prediabetes is 5.7% to 6.4%. Diabetes is 6.5% or higher.

Why SCT throws a wrench into it. Most A1C testing methods rely on measuring slightly modified hemoglobin proteins. People with sickle cell trait carry a different kind of hemoglobin (HbS), and depending on which testing method your lab uses, the machine can read your A1C as falsely high or falsely low.

The consequences are real:

• Falsely high → you might be treated for diabetes you don't actually have, with side-effect-prone medications.
• Falsely low → you and your doctor might miss diabetes that is there, until complications show up.

What to do — three short asks at your next appointment:

1. "Doc, I have sickle cell trait. Is my A1C result reliable for that test method?" Your provider can call the lab. Some methods (HPLC, certain ion-exchange assays) are unaffected by HbS. Others give false readings.

2. "Can we use a different test to confirm?" Fasting glucose, oral glucose tolerance, fructosamine, glycated albumin, or continuous glucose monitoring all bypass the hemoglobin issue and can confirm what's really going on.

3. "Is my SCT noted in my chart?" If you can't remember whether your trait status is documented, ask. It should be in there permanently — it affects more than just diabetes testing.

For everyone — not just people with diabetes: This isn't only relevant if you've already been diagnosed. The A1C is also used to screen people for diabetes during routine physicals. If you have SCT, ask your provider whether the screening method is reliable, or use a fasting glucose instead.

The good news: there are accurate tests for everyone. You just have to ask.

If you are the team physician or athletic trainer, you are the medical eye on the sideline. When sickle cell trait (SCT) is in the room, your job is twofold: protect the athlete and protect their dignity. Both matter.

The good news first: SCT is not a contraindication to sport. The athletes you serve can compete in every sport at every level. What we owe them is a program built on universal safe-training practices — practices that protect every athlete, with or without SCT.

Before the season starts:

• Run thorough pre-participation evaluations. Capture history of cramping, heat illness, asthma, hypoglycemia, and SCT status if known.
• Educate your coaches and strength staff on environmental risk factors — altitude, heat index, humidity — and on the medical conditions that can affect performance.
• Build a written Emergency Action Plan for every venue. Test it. Rehearse it.
• Equip your sideline: ice tubs, AED, communication plan, transport route.

During training and competition:

• Set a safe pace. Acclimatize over 7–14 days when conditions or altitude change.
• Be ready to modify the activity if conditions cross your safety thresholds.
• Encourage athletes to report symptoms early — make it culturally safe to come out of a drill.
• Recognize the picture of exertional sickling: muscle weakness, burning, cramping, rapid shallow breathing without wheezing, prolonged fatigue. Unlike sudden cardiac arrest, the athlete is often still talking. Stop activity, cool, hydrate, escalate care.

For the athlete with known SCT:

• Reinforce hydration, gradual conditioning, and altitude awareness.
• Encourage genetic counseling if they haven't received it — SCT has reproductive implications they deserve to understand.
• Protect the privacy of their trait status. It belongs in their medical record, not in the locker room.

Two phrases to retire: "toughen up" and "push through it." Both have cost lives. The athletes I have lost in my career were not weak; they were unrecognized.

Universal safe training, written emergency plans, and a culture of "report it early" — that is the SCT playbook.

Most patients with sickle cell trait (SCT) live entirely normal lives, and most clinicians will never manage a complication directly attributable to SCT. But there is one presentation worth keeping bookmarked in the differential: splenic infarct at altitude.

The clinical picture. Splenic infarct in SCT typically occurs above 1,100 meters (about 3,600 feet) and is usually triggered by exercise, dehydration, or both. The patient — often a previously well young adult who has recently flown into Denver, hiked Flagstaff, or trained at altitude — presents with sudden, persistent left upper-quadrant abdominal pain, sometimes radiating to the left shoulder (Kehr's sign), pleuritic chest pain, and nausea. Modern pressurized commercial flight is generally safe; the risk is unpressurized aviation and sustained time at altitude.

The workup. Confirm SCT status if not already documented. Imaging — typically CT with contrast — confirms the infarct. Rule out concurrent pathology, including pneumonia, pulmonary embolism, and acute splenic sequestration (the last would point you back toward unrecognized sickle cell disease rather than trait).

Management.

• Move the patient to lower altitude when stable.
• Supportive care: IV hydration, supplemental oxygen, analgesia.
• Reserve splenectomy for refractory cases after other options are exhausted.
• Arrange close outpatient follow-up to monitor for splenic abscess, the most concerning downstream complication.

Counseling for prevention. When the patient is recovering, this is a teachable moment. Patients with SCT should:

• Hydrate aggressively before and during altitude exposure.
• Acclimatize gradually — don't fly into Denver and run a 10K the next morning.
• Pace exercise with frequent rest at altitude.
• Know that a single splenic infarct does not preclude future altitude travel; it does demand smarter precautions.

Bigger picture. A patient who learns they have SCT through a complication deserves a follow-up conversation that goes beyond the acute episode — including reproductive counseling and education about the (rare) other SCT-associated risks: hematuria, post-hyphema glaucoma, and exertional rhabdomyolysis.

Rare doesn't mean ignorable. Add this one to the mental shortlist.

Here is a quiet quality-of-care issue that hides in plain sight: the hemoglobin A1C assay can be unreliable in patients with sickle cell trait (SCT). Depending on the method your lab runs, A1C can read falsely high or falsely low — meaning your "well-controlled" patient may actually be hyperglycemic, or your "uncontrolled" patient may be receiving treatment they don't need.

This isn't a small population. SCT affects roughly 1 in 12 Black or African American patients in the U.S., plus meaningful numbers of patients with Mediterranean, Middle Eastern, South American, and South Asian heritage. If you treat diabetes, you treat SCT.

Three things every primary care, endocrinology, and internal medicine clinician should do:

1. Know your patient's hemoglobin status. SCT is identified through hemoglobin electrophoresis, HPLC, or DNA testing — not through the A1C itself. An A1C that flags a "variant hemoglobin" is a signal, not a diagnosis. Confirm separately.

2. Know your lab's method. Call your reference lab and ask which A1C method they use, and whether it is validated for HbS interference. The National Glycohemoglobin Standardization Program (NGSP) maintains a public list of which methods are reliable in the presence of common hemoglobin variants. Bookmark it: ngsp.org/interf.asp.

3. Have a backup plan. If your lab's method is affected by HbS, supplement A1C with fructosamine, glycated albumin, or continuous glucose monitoring to confirm glycemic control. Don't titrate insulin off a number you can't trust.

A note on equity. Patients with SCT have historically received the same A1C-driven care as everyone else, even when the test was misleading them. That's a measurable contributor to disparate diabetes outcomes in Black communities. Fixing it costs nothing — a phone call to the lab and a habit of asking, "Has this patient ever been tested for hemoglobin variants?"

When the A1C and the clinical picture don't match, trust your eyes and order the better test.

When a patient with sickle cell trait (SCT) presents with hematuria — visible (gross) or microscopic — the most important thing to remember is what not to do: do not attribute the bleeding to SCT until everything else has been ruled out.

That sounds obvious. In practice, it gets skipped, and the cost of skipping it can be enormous. Hematuria in SCT can occur because of papillary necrosis or microvascular changes in the renal medulla, but it can also herald renal medullary carcinoma (RMC) — a rare, aggressive cancer that occurs almost exclusively in patients with sickle hemoglobin (most often SCT) and that gets confused for benign trait-related bleeding. RMC's prognosis is dramatically better with early detection.

The workup. Treat hematuria in an SCT patient the same as in any patient — comprehensively.

• History and physical: trauma, infection, exercise pattern, hydration, family history of urologic malignancy, flank pain, weight loss.
• Urinalysis with microscopy to confirm red cells (and check for casts, crystals, infection).
• Urine culture if pyuria is present.
• Imaging: CT urogram or MRI for any patient with gross hematuria, persistent microscopic hematuria, flank pain, or risk factors. Don't skip imaging just because the patient has SCT.
• Cystoscopy when indicated by age, smoking history, or red flags.
• Referral to nephrology and/or urology for any unclear case.

Common alternative causes you should walk through systematically: intrinsic glomerular disease, urinary tract infection, nephrolithiasis, trauma, and malignancy.

Treatment when SCT is the cause. Most SCT-related hematuria responds to conservative measures — increased oral hydration, rest, activity restriction, and management of any underlying triggers. Refractory bleeding needs urology.

The teachable moment. Patients with SCT — especially young Black patients — have been historically underserved on this exact issue. A thorough workup and a conversation about RMC isn't fearmongering; it's standard of care. Then send them home with hydration counseling and a follow-up plan.

When in doubt, image. When still in doubt, refer.

Eye trauma plus sickle cell trait (SCT) is a combination every emergency physician, primary care clinician, and sports-medicine provider should treat as time-critical. The risk is glaucoma post-hyphema — a rapid rise in intraocular pressure (IOP) following bleeding into the anterior chamber — and patients with SCT develop it more readily than the general population.

Why SCT changes the rules. Red cells with HbS sickle in the relatively hypoxic, acidic environment of the anterior chamber. Sickled cells obstruct the trabecular meshwork, IOP climbs, and the optic nerve is at risk. Some standard glaucoma medications — particularly carbonic anhydrase inhibitors — can worsen sickling in the anterior chamber. Drug choice matters.

What to do at first contact: 1. Refer to ophthalmology emergently. Not later today. Now. 2. While arranging transfer, protect the eye — rigid shield, no patching that applies pressure, head of bed elevated to 30°. 3. Communicate the patient's SCT status to the ophthalmologist explicitly. They will choose IOP-lowering agents that are safe in sickling conditions. 4. Limit activity, restrict Valsalva, address pain and nausea (vomiting raises IOP).

What ophthalmology will manage:

• Bedrest, sedation if rebleeding risk is high.
• Topical cycloplegics and corticosteroids per protocol.
• IOP monitoring multiple times a day.
• Anti-fibrinolytics in select cases.
• Surgical intervention (anterior chamber washout) if IOP cannot be controlled within 24 hours — earlier in SCT than in non-SCT patients.

Counseling after stabilization: any patient who learns they have SCT in the context of an eye injury deserves a follow-up conversation. Cover protective eyewear in sport, the (rare) other SCT-related risks, and reproductive implications.

The line I tell residents: In a patient with SCT, every hyphema is a high hyphema until ophthalmology says otherwise.

In 2010, a federal advisory committee — the Secretary's Advisory Committee on Heritable Disorders in Newborns and Children (SACHDNC) — wrote a public letter to the U.S. Department of Health and Human Services raising concerns about a sports policy that's still in effect today. The NCAA requires Division I athletes to be screened for sickle cell trait (SCT). Many high schools and athletic associations followed suit.

The committee's concern wasn't with screening itself. It was with the purpose of the screening, who carries the consequences, and what the alternative should have been.

Here's the substance — because this conversation matters as much in 2026 as it did then.

The committee's argument, simplified:

1. The science is mixed. Even after years of attention, it remains unclear how much sickle cell trait independently contributes to exercise-related sudden death. In many fatal cases reviewed, sickled cells were found at autopsy — but post-mortem sickling occurs after death from any cause in someone with SCT. That's a confounder.

2. The deaths in question were rare and largely preventable — for all athletes. Military studies showed that gradual exercise progression, hydration, and adequate rest cut exercise-related deaths across the board, regardless of trait status. Universal safe-training practices would protect everyone — without singling anyone out.

3. Singling out athletes by genetic status creates risk of stigma and discrimination. This is the heart of it. SCT is most common in Black and brown athletes. A screening program targeted at trait — without strong privacy protections, without educational support, and without changes in how everyone is trained — risks turning a genetic difference into a job-fitness label.

4. The right home for genetic screening is the medical home — not the locker room. Newborn screening already identifies SCT in nearly every American newborn since 2006. The problem isn't a lack of testing; it's a lack of follow-through. People deserve to know their status — but in the context of medical counseling, family planning conversations, and informed consent. Not as a precondition for a roster spot.

5. Genetic privacy laws (GINA) protect against discrimination in employment and health insurance — but not in athletics. That gap matters.

The committee's recommendations were direct:

• Universal safe-training guidelines for all athletes.
• Education for coaches and trainers on heat illness and exertional sickling.
• Genetic screening kept inside the medical home, with privacy and counseling built in.
• More research, not more single-group screening.

Where this leaves families today. You should know your sickle cell status. So should your kids. The right path is the same one the committee recommended in 2010: testing through your provider, with counseling, with privacy. When schools and teams ask for trait status, you have a right to ask in return: What does the team do with this information? Who has access? What changes about my child's training plan?

Knowledge belongs to you. Use it on your terms.
