Maternal Serum Alpha-Fetoprotein (MSAFP):
Alpha-fetoprotein (AFP) is a protein that is normally produced by the fetus' liver.
Maternal Serum Alpha-Fetoprotein (MSAFP)
Alpha-fetoprotein (AFP) is a protein that is produced by the fetus' liver. A small amount crosses the placenta and moves into the mother's blood stream.
The maternal serum triple screen, sometimes called the triple test or MSAFP+ test, measures the amounts of three substances in a pregnant woman's blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol (uE3).

Maternal Serum Alpha-fetoprotein (MSAFP)
What It Is:
Measuring MSAFP helps to identify women carrying a fetus with certain birth defects. MSAFP measures a protein that is made in the fetus and finds its way into the maternal blood stream.
Maternal Serum Screening
alpha-fetoprotein- this blood test measures the levels of alpha-fetoprotein (AFP), a protein released by the fetal liver and found in the mother's blood. AFP is sometimes called MSAFP (maternal serum AFP).
Maternal serum alpha-fetoprotein (MSAFP)
The developing fetus has two major blood proteins--albumin and alpha-fetoprotein (AFP).

The test you describe is a simple blood test which can be evaluated for something called maternal serum alphafetoprotein (MSAFP). MSFAP is a protein made by the fetal yolk sac in early pregnancy and later on by the fetal liver.

MSAFP: Abbreviation for maternal serum alpha-fetoprotein screening. A blood test given to the expectant mother between weeks 15 and 18 of pregnancy to screen for an increased risk of the baby having a birth defect.
First-trimester screening using a combination of nuchal translucency and maternal serum testing offers several potential advantages over second-trimester screening.

AFP is a protein normally produced by the fetal liver and is present in the fluid surrounding the fetus (amniotic fluid), and crosses the placenta into the mother's blood. The AFP blood test is also called MSAFP (maternal serum AFP).
If maternal serum AFP is elevated and all of the testing (ultrasound and amnio) are normal, there is still an increased risk for maternal and fetal problems in pregnancy, and the pregnancy will need to be followed more closely, ...
