The Double Marker Test is a prenatal screening test performed during the first trimester of pregnancy to assess the risk of chromosomal abnormalities like Down syndrome (Trisomy 21) and Edwards syndrome (Trisomy 18) in the fetus. This blood test measures two key biomarkers: Free Beta hCG (Human Chorionic Gonadotropin): Elevated levels may indicate a higher risk of chromosomal abnormalities. PAPP-A (Pregnancy-Associated Plasma Protein-A): Lower levels may suggest potential genetic disorders. The Double Marker Test is typically conducted between 9 to 14 weeks of pregnancy and is often combined with an ultrasound (NT scan) for more precise results. It is a non-invasive and safe test that helps doctors decide if further diagnostic procedures, such as amniocentesis or chorionic villus sampling (CVS), are needed.
