What does PAPP-A stand for?

PAPP-A stands for Pregnancy Associated Plasma Protein-A. This is a protein produced by the placenta during pregnancy and is involved in various physiological processes. PAPP-A is often measured in maternal blood during the first trimester to help assess the risk of certain chromosomal abnormalities, such as Down syndrome. Monitoring levels of PAPP-A can provide important information about the health and development of both the mother and the fetus. The significance of PAPP-A is well established in prenatal screening, which contributes to early detection and management options for expectant mothers.
