Triple Marker test

Triple marker test also called second trimester screening is a 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 and AFP(Alpha fetoprotein).

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