anticardiolipin antibodies

Anticardiolipin antibodies are immune proteins that mistakenly target a component of cell membranes called cardiolipin. These antibodies are associated with an increased risk of blood clots and certain autoimmune conditions, such as antiphospholipid syndrome. When present, they can interfere with normal blood clotting processes, potentially leading to complications like deep vein thrombosis, stroke, or pregnancy issues. Testing for anticardiolipin antibodies helps doctors diagnose and manage these conditions, especially when unexplained clotting problems or recurrent pregnancy loss occur. Their presence indicates an abnormal immune response that affects blood vessel function.
