Why it is Done

For pregnant women, to assess the risk of having a baby with certain chromosomal disorders, such as Down syndrome (trisomy 21) or Edwards syndrome (trisomy 18), or open neural tube defects, such as spina bifida.

What is this test

Maternal serum screening, or the multiple marker test, measures several substances in the blood of a pregnant woman in the second trimester of pregnancy. The results can be used to determine the risk that the baby has a chromosome disorder or neural tube defect such as spina bifida.

These substances include the following- Alpha-fetoprotein (AFP), Human chorionic gonadotropin (hCG), Unconjugated estriol (uE3) and Inhibin A. When the first three substances are measured together, it is called a triple screen. When the fourth substance, inhibin A, is added, it is called a quad screen.
