The importance of the MSAFP test lies in its ability to identify potential neonatal disorders early in the pregnancy. Elevated or low levels of AFP in the mother's blood can indicate an increased risk of conditions such as neural tube defects (e.g., spina bifida) and chromosomal abnormalities (e.g., Down syndrome). Early detection through the MSAFP test allows for further diagnostic testing and enables parents and healthcare providers to make informed decisions regarding the pregnancy and necessary preparations for the child's birth.
