What is MSAFP?

MSAFP stands for Maternal Serum Alpha-Fetoprotein. It is a protein that is produced by the fetal liver and can be found in the mother’s blood during pregnancy. The measurement of MSAFP is utilized in prenatal screening to assess the risk of certain fetal developmental issues, such as neural tube defects and Down syndrome. Abnormal levels of MSAFP can indicate potential fetal complications, prompting further diagnostic testing. This makes option B the most accurate choice, as it highlights the role of MSAFP in indicating potential issues during fetal development.
