Quizplus · Accepted Answer

Alpha-fetoprotein assay is used to detect neural tube defects, such as spina bifida, in the developing fetus. It is a blood test that measures the levels of alpha-fetoprotein, a protein produced by the fetus and found in the amniotic fluid and maternal blood. High levels of alpha-fetoprotein can indicate a neural tube defect, while low levels can indicate Down syndrome. It cannot assess sex chromosome abnormalities, degree of mental retardation, or measure insulin levels in the fetus.
