An **Antiphospholipid Antibody (APLA) Profile Test** is a specialized group of blood tests used to diagnose Antiphospholipid Syndrome (APS), an autoimmune condition. In APS, the body mistakenly produces autoantibodies against its own proteins bound to phospholipids. This reaction significantly increases the risk of abnormal blood clotting in veins or arteries, as well as pregnancy complications like recurrent miscarriages.
The APLA panel typically measures three primary markers: lupus anticoagulant, anticardiolipin antibodies, and anti-beta-2 glycoprotein I antibodies. Identifying these autoantibodies helps clinicians evaluate a patient's risk of thrombotic events, guiding appropriate preventive care and targeted anticoagulant treatments.
