How do I know if I have Sickle Cell Anemia?

Sickle Cell Anemia is diagnosed definitively through a simple blood test called hemoglobin electrophoresis, which identifies the presence of abnormal hemoglobin S. If you suspect you have the condition, you should look for patterns of unexplained chronic fatigue, recurring episodes of severe pain (pain crises), or frequent infections, and request a hemoglobin solubility or electrophoresis test from your primary care provider.

What are the early signs and symptoms of Sickle Cell Anemia?

Sickle Cell Anemia is a genetic blood disorder where red blood cells become crescent-shaped, causing them to clump together and block blood flow. Because this affects oxygen delivery throughout the body, symptoms often appear in early childhood, though some individuals may not experience severe complications until later. Common indicators include chronic anemia (leading to persistent tiredness and pale skin), delayed growth or puberty, and recurring episodes of pain, known as "vaso-occlusive crises." These pain episodes can occur anywhere in the body but are most commonly felt in the chest, abdomen, joints, and bones.

How do I know if I should be tested for Sickle Cell Anemia?

If you are experiencing symptoms, it is important to look for patterns rather than isolated incidents. Consider the following checklist when preparing for a doctor's visit:

• Recurring pain: Do you experience unexplained, intense pain episodes that last for hours or days?


• Family history: Does anyone in your family carry the sickle cell trait or have a history of Sickle Cell Anemia?


• Infection frequency: Do you suffer from frequent or severe infections, such as pneumonia?


• Fatigue: Is your fatigue persistent, even after adequate rest, and accompanied by shortness of breath or dizziness?


• Jaundice: Do you notice a persistent yellowing of the skin or the whites of your eyes, which can be a sign of red blood cell breakdown?

Which medical tests can confirm Sickle Cell Anemia?

You cannot diagnose Sickle Cell Anemia through standard symptoms alone; clinical confirmation is required. When you speak with your doctor, specifically ask for a hemoglobin electrophoresis test. This is the gold standard for diagnosing Sickle Cell Anemia, as it separates the different types of hemoglobin in your blood to identify the presence and percentage of hemoglobin S. Other tests, such as a Complete Blood Count (CBC) or a peripheral blood smear, may show signs of anemia or abnormally shaped cells, but they are not sufficient for a definitive diagnosis.

What should I do if my concerns are dismissed?

It is common for patients to feel unheard, especially if symptoms are intermittent. If your doctor dismisses your concerns, do not hesitate to advocate for yourself. Request that your doctor document in your medical record that you requested testing for Sickle Cell Anemia and note their reason for declining it. If you remain concerned, seek a second opinion from a hematologist—a specialist in blood disorders—who has experience with hemoglobinopathies.

When do I need urgent medical evaluation?

Certain symptoms associated with Sickle Cell Anemia require immediate emergency care. Seek medical attention right away if you experience:

• Fever over 101°F (38.3°C).


• Sudden, severe chest pain or difficulty breathing (which could indicate acute chest syndrome).


• Stroke symptoms, such as sudden weakness or numbness on one side of the body, confusion, or vision changes.


• Severe abdominal pain or swelling.

Next steps

• Schedule an appointment with your primary care physician to discuss your specific symptoms and family history.


• Request a hemoglobin electrophoresis test specifically to rule out or confirm Sickle Cell Anemia.


• Consult a hematologist if you have a family history of the disease or if initial tests are inconclusive.
