What this test is
This test examines hemoglobin, the protein in red blood cells that carries oxygen, to look for an abnormal form called hemoglobin S. Hemoglobin S can cause red blood cells to become stiff and sickle-shaped, which may lead to health problems. Screening can show whether a person has sickle cell trait, sickle cell disease, or neither.
What it measures
- Hemoglobin S — Presence indicates sickle cell trait or disease
- Hemoglobin A — Normal hemoglobin; its amount helps distinguish trait from disease
- Hemoglobin F — Fetal hemoglobin, sometimes measured to assess severity
- Hemoglobin C — Another abnormal hemoglobin that may be detected
What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to check for sickle cell trait or disease, especially if there is a family history or symptoms such as unexplained pain or anemia. It is also commonly offered before or during pregnancy to assess the chance of passing the condition to a child.
Preparation
No special preparation is usually needed, but follow the instructions provided by the collection lab. If you have questions about fasting or medications, ask the lab directly.
How results are reported
Results are typically reported as positive or negative for hemoglobin S, or as a description of the hemoglobin types found. Reference ranges and reporting formats can vary by laboratory, so your clinician will interpret the findings in your specific context.
