Order Sickle Cell Anemia Screening TestThe Sickle Cell Anemia Screening Test is a laboratory evaluation used to detect the presence of abnormal hemoglobin that can cause sickle cell disease. It is typically ordered when a person has symptoms suggestive of the condition, when there is a family history of sickle cell disease, or as part of newborn screening programs. The test helps identify whether a person carries a sickle cell trait or has a form of sickle cell anemia.
About Sickle Cell Anemia Screening Test in Fullerton
Understanding the hemoglobin variants that underlie sickle cell disease is essential for interpreting screening results.
Sickle cell disease is caused by a mutation in the HBB gene, which leads to the production of abnormal hemoglobin S (HbS). Under low-oxygen conditions, HbS molecules polymerize, causing red blood cells to become rigid and crescent-shaped. These sickled cells can block blood flow, leading to pain, organ damage, and anemia.
Screening typically begins with a solubility test or a hemoglobin electrophoresis. Solubility tests detect the presence of HbS but cannot distinguish between sickle cell trait and sickle cell disease. Hemoglobin electrophoresis or high-performance liquid chromatography (HPLC) separates different hemoglobin types, allowing identification of HbS, HbC, HbE, and other variants, as well as quantifying normal hemoglobins like HbA and HbF.
The test requires a blood sample, usually collected from a vein in the arm. No special preparation is generally needed, though the lab may provide specific instructions. Results are typically available within one to three business days. A positive screening result is often confirmed with additional testing, such as genetic analysis, to establish a definitive diagnosis.
