The Sickle Cell DNA PCR (Polymerase Chain Reaction) test is a genetic test used to detect the presence of the sickle cell gene mutation in an individual’s DNA. The test identifies mutations in the HBB gene, which encodes the hemoglobin protein responsible for carrying oxygen in red blood cells. The test specifically looks for the sickle hemoglobin variant (HbS), which can cause sickle cell disease (SCD) when inherited in a homozygous form (two copies of the sickle cell gene) or sickle cell trait (one copy of the sickle cell gene).

    Description

    Purpose of the Test:
    • Diagnose sickle cell disease or sickle cell trait
    • Identify carriers of the sickle cell gene, even if they do not show symptoms
    • Confirm a diagnosis when hemoglobin electrophoresis results are inconclusive
    • Screen newborns or individuals with a family history of sickle cell disease
    • Help with genetic counseling for families at risk of having a child with sickle cell disease

    What the Test Involves:
    • A blood sample is drawn, typically from a vein in your arm
    • The DNA is extracted from the white blood cells and analyzed using PCR technology
    • The PCR process amplifies specific regions of the HBB gene to identify the presence of the HbS mutation
    • The test can identify whether the individual has:
    o Sickle Cell Disease (homozygous HbSS)
    o Sickle Cell Trait (heterozygous HbAS)
    o Normal hemoglobin genotype (HbAA)
    • This test is highly accurate and can detect even small amounts of sickle cell DNA
