Double Marker Test – Vital First Trimester Screening for Fetal H, Noida

The Double Marker Test is an important prenatal screening conducted during the first trimester, usually between the 9th and 13th weeks of pregnancy. This non-invasive blood test measures levels of Free Beta-hCG and PAPP-A (Pregnancy-Associated Plasma Protein A) to evaluate the risk of chromosomal abnormalities such as Down syndrome (Trisomy 21) and Edwards syndrome (Trisomy 18) in the fetus. Often recommended alongside the Nuchal Translucency (NT) scan, the Double Marker Test helps identify pregnancies that may need further diagnostic tests like NIPT or amniocentesis. While it doesn’t provide a definitive diagnosis, it plays a crucial role in early detection and supports informed decision-making for expecting parents. The test contributes significantly to prenatal care by offering insight into the baby’s development during a critical stage of pregnancy.
