Double Marker Test Early Pregnancy Screening for Genetic Risk, Noida

The Double Marker Test is a first-trimester prenatal screening test, usually conducted between the 9th and 13th weeks of pregnancy, to assess the risk of chromosomal abnormalities in the fetus. It measures two important biochemical markers in the mother's blood — free Beta-hCG and PAPP-A (Pregnancy-Associated Plasma Protein-A). Abnormal levels of these markers may indicate a higher likelihood of conditions such as Down syndrome (Trisomy 21) or Edwards syndrome (Trisomy 18).

This test is often paired with a Nuchal Translucency (NT) scan for more accurate risk assessment. While the Double Marker Test does not diagnose any disorder, it helps identify pregnancies that may benefit from further diagnostic tests like NIPT, amniocentesis, or CVS. It is non-invasive, safe, and especially recommended for women over 35 or those with a family history of genetic conditions, offering valuable insight into fetal health early in pregnancy.
