The Double Marker Test (also known as the First Trimester Screen or Combined Test) is a non-invasive prenatal screening test offered to pregnant women, typically performed between 10 weeks and 13 weeks + 6 days of gestation.
The test measures the levels of two specific biochemical markers in the mother's blood:
The results of these blood tests are combined with an ultrasound measurement called the Nuchal Translucency (NT) scan to assess the mother's statistical risk of carrying a fetus with certain chromosomal abnormalities, specifically Down Syndrome (Trisomy) and Edwards Syndrome (Trisomy 18).
At Augmentum Diagnostics, an NABL Accredited Lab in Delhi, we ensure the accurate measurement of these prenatal markers, which is vital for providing expectant parents with timely risk assessment and counseling.
