Quad Marker Screen Test Index
The quad marker screen determines if a woman is at higher or lower risk of carrying a baby with a birth defect. This test may only be administered between 15 and 20 weeks of pregnancy. A quad marker screen tests for the presence of alpha-fetoprotein, unconjugated estriol, human chorionic gonadotropin, and inhibin-A. If the results of the quad marker screen test are abnormal, further tests may be necessary.
