Maternal Serum Alpha-Fetoprotein (MSAFP)

Maternal Serum Alpha-Fetoprotein (MSAFP) is a blood test performed during pregnancy, usually between the 15th and 20th weeks, to measure the level of alpha-fetoprotein (AFP), a protein produced by the developing fetus. Abnormal AFP levels can indicate potential issues, such as neural tube defects (like spina bifida) or chromosomal disorders (like Down syndrome). While MSAFP is a useful screening tool, it’s important to remember that it doesn't provide a definitive diagnosis. If results are unusual, further testing may be recommended to assess the health of the fetus more accurately.
