The Double Marker Test is a prenatal screening test performed during the first trimester of pregnancy to assess the risk of chromosomal abnormalities in the baby, such as Down syndrome and Trisomy 18. It measures the levels of two specific substances in the mother’s blood—free beta-hCG and PAPP-A—along with the ultrasound measurement of nuchal translucency. This test helps doctors identify pregnancies that may require further diagnostic evaluation, offering reassurance to expectant parents or guiding necessary next steps. The Double Marker Test is non-invasive and plays an important role in ensuring the health and well-being of both the mother and the baby.
