The
Double Marker Test is a prenatal blood test performed during the first trimester of pregnancy, typically between the 9th and 13th weeks. It helps assess the risk of chromosomal abnormalities in the fetus, such as Down syndrome (Trisomy 21) and Trisomy 18. The test analyzes two key markers in the mother's blood—Free Beta-hCG and PAPP-A (Pregnancy-Associated Plasma Protein A)—to determine potential genetic risks.
The Double Marker Test is usually recommended along with a nuchal translucency (NT) scan for more accurate screening results. It is a non-invasive test and poses no risk to the mother or the baby.
In India, the cost of the Double Marker Test ranges from ₹1,500 to ₹3,500, depending on the diagnostic center and location. It is especially advised for women over 35, those with a family history of genetic disorders, or as part of routine prenatal care.
Early screening with the Double Marker Test helps expectant parents make informed decisions and manage pregnancy with better care and confidence.
