Quadruple marker test

Quadruple marker test is a second trimester screening test for pregnant women in their second trimester of pregnancy to screen for risk of fetal abnormalities. This test can determine a baby's risk for down syndrome and NTD(neural tube defects) by evaluating maternal health and crucial serum markers such as Free beta HCG(Human chorionic gonadotropin), estriol, inhibin A and AFP(Alpha fetoprotein).

This test can be done between GA (gestational age) 15-19 weeks as recommended by your gynecologist/obstetrician.
