What is Maternal Serum Alpha Fetoprotein (MSAFP) Test?
The maternal serum alpha fetoprotein (MSAFP) test is a blood test performed during pregnancy to screen for certain congenital disabilities and chromosomal abnormalities in the developing fetus. Alpha-fetoprotein (AFP) is a protein produced by the fetal liver, and its levels can be measured in the mother's blood. The MSAFP test is typically conducted during the second trimester, between weeks 15 and 20 of pregnancy.
