MSAFP is an indicator of the presence of AFP (a plasma protein normally produced by the fetus) in the mother's blood. MSAFP serves as the basis for some valuable tests.
An MSAFP screen involves a simple blood draw from the mother's vein. Results are usually available in one to two weeks. Up to 10% of results are positive, meaning you have high- or low-AFP levels.
MSAFP - maternal serum alpha fetoprotein A blood test done to indicate an increased risk for defects of the spine.
OB - obstetrician A physician who specializes in pregnant women, pregnancy issues and birth.
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.
THE MSAFP, MSAFP-PLUS OR "TRIPLE TEST" Blood Tests
The MSAFP blood test measures the amount of a protein called AFP, or alpha feto-protein, in the mother's blood. It is a screening test that is recommended for all pregnant women.

However, the MSAFP can be elevated for a variety of reasons which are not related to fetal neural tube or abdominal wall defects, so this test is not 100% specific.
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.
The triple screen test checks the levels of maternal serum alpha-fetoprotein (MSAFP), unconjugated estradiol (UE3) and beta human chorionic gonadotrophin (beta-hCG) in the blood.
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).
The Quad Screen or the MSAFP (Maternal Fetal Serum Alfa Protein) is a prenatal blood test which is usually offered to patients routinely between the 17th and 22nd week of pregnancy.

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).
