The Double Marker Test is a vital prenatal screening test done in the first trimester, typically between the 9th and 13th week of pregnancy. It measures levels of Free Beta-hCG and PAPP-A in the mother’s blood to assess the baby’s risk of chromosomal abnormalities such as Down syndrome (Trisomy 21) and Edwards syndrome (Trisomy 18).
This non-invasive test is often paired with a Nuchal Translucency (NT) scan for better accuracy. While it doesn’t confirm a disorder, it helps doctors determine if further diagnostic tests like NIPT or amniocentesis are necessary.
Early screening with the Double Marker Test supports informed decisions and better prenatal care.
