What implication does an elevated MSAFP typically suggest?

An elevated Maternal Serum Alpha-Fetoprotein (MSAFP) level is an important marker in prenatal screening. Typically, increased levels of MSAFP suggest the potential for fetal abnormalities or complications. This is because MSAFP is produced by the fetal liver and its elevated levels in maternal blood can be associated with conditions such as neural tube defects (e.g., spina bifida, anencephaly) or abdominal wall defects (e.g., omphalocele, gastroschisis).

Additionally, elevated MSAFP may indicate other issues related to fetal health, including multiple gestations or certain types of placental complications. While elevated MSAFP can prompt further testing and monitoring, it is crucial to understand that it does not confirm a diagnosis on its own; it necessitates further evaluation through targeted ultrasound or additional testing. This screening tool helps healthcare providers identify pregnancies that may require more in-depth investigation, making early intervention possible if necessary for the health of the fetus.
