The Double Marker Test is an important prenatal screening done during the first trimester of pregnancy (11th–14th week) to evaluate the risk of chromosomal abnormalities in the unborn baby. It measures two key markers in the mother’s blood—free Beta-hCG (human chorionic gonadotropin) and PAPP-A (Pregnancy Associated Plasma Protein-A). Abnormal levels of these markers may suggest a higher risk of genetic disorders such as Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), or Patau syndrome (Trisomy 13). The test is often combined with an NT (Nuchal Translucency) scan for more accurate results. While it does not provide a final diagnosis, it helps doctors identify whether further genetic testing is required.
