The Maternal Serum AFP test contains 1 test with 20 biomarkers.
Maternal serum alpha-fetoprotein (MSAFP) is used for prenatal screening of open neural tube defects (ONTD). MSAFP screening detects 88% of anencephaly and 79% of open spina bifida with a 3% false positive rate. Normal results do not ensure birth of a normal infant. In addition, 2-3% of newborns have some type of physical or mental defect, many of which may be undetectable with current prenatal diagnostic procedures.
