Why This Biomarker Matters

Abnormal amniotic fluid AFP levels suggest possible fetal abnormalities. Early detection guides further diagnostic testing and allows informed decision-making and pregnancy management.

Overview

Alpha-fetoprotein (AFP) is a protein produced during pregnancy, measured in amniotic fluid to assess fetal health and development. Abnormal AFP levels in amniotic fluid can indicate neural tube defects (like spina bifida), chromosomal abnormalities, or other fetal problems. This test is typically performed as part of prenatal screening, usually between 15-20 weeks of pregnancy. Results help guide further testing and monitoring decisions.
