The Double Marker Test is a crucial prenatal screening test performed during the first trimester of pregnancy, usually between the 9th and 13th weeks. It helps evaluate the risk of chromosomal abnormalities in the fetus, such as Down syndrome (Trisomy 21) and Edward’s syndrome (Trisomy 18). This blood test measures two key markers in the mother's blood—free Beta hCG and PAPP-A (Pregnancy-Associated Plasma Protein A). When combined with an NT (Nuchal Translucency) scan, the test offers greater accuracy in detecting potential genetic disorders. The Double Marker Test is non-invasive and plays an important role in early detection, enabling parents and healthcare providers to plan further diagnostic steps and prenatal care if needed.
