Pregnancy-Associated Plasma Protein-A (PAPP-A)

What is PAPP-A?

Pregnancy-Associated Plasma Protein-A (PAPP-A) test monitors the PAPP-A released by the placenta during pregnancy. A low level of PAPP-A might indicate the risks of genetic defects in the fetus. This test helps in assessing the risk of aneuploidies including trisomy 21 and down syndrome in the developing baby during first and second trimester of pregnancy.
