Sickle Cell Screen
Also known as: Hemoglobin S
Clinical Use
Order TestUse
This is a screening test to determine the presence of sickling hemoglobins (e.g., hemoglobin S, hemoglobin C‑Harlem), used to assess individuals at risk of sickle cell crises in conditions like prolonged anoxia during surgery, athletic programs, or high altitude environments.
