The Anti-Phospholipid Antibody (aPL) IgM Test is a diagnostic blood assay used to detect Immunoglobulin M (IgM) antibodies that bind to various phospholipids (fats) and associated proteins (like beta_2-glycoprotein I) in the plasma. The primary purpose of this test is to screen for Antiphospholipid Syndrome (APS), an autoimmune disorder that increases the risk of thrombosis (blood clots) and complications during pregnancy.
