Question

Quizplus · Accepted Answer

AFP (alpha-fetoprotein) is a prenatal test that can detect neural tube disorders, such as spina bifida, and multiple gestations. CVS (chorionic villus sampling) can also detect these conditions, but it is a more invasive test that carries a higher risk of miscarriage. CST (contraction stress test) is a test performed later in pregnancy to assess fetal well-being, and PKU (phenylketonuria) is a newborn screening test for a metabolic disorder.
