Double Marker Test – Timing, Purpose, Report Interpretation & Cost in India
The Double Marker Test is a prenatal screening test conducted during the first trimester (9–13 weeks) of pregnancy. It helps assess the risk of chromosomal abnormalities such as Down syndrome (Trisomy 21) and Edwards syndrome (Trisomy 18) in the fetus. This test measures two key markers in the mother’s blood: Free Beta-hCG and PAPP-A (Pregnancy-Associated Plasma Protein A).
The Double Marker Test is often combined with an NT scan to improve accuracy. It is non-invasive and recommended especially for women above 35 or those with a family history of genetic disorders.
In India, the Double Marker Test price typically ranges from ₹1,500 to ₹3,500, depending on the diagnostic center and city. Test results are usually available within 3 to 5 working days.
