Cardiolipin antibodies are autoantibodies, meaning they mistakenly attack your body instead of protecting it. Specifically, these antibodies target cardiolipin, a phospholipid (a type of fat) found in your cells.
These cardiolipin antibodies are linked to problems with blood clotting and certain autoimmune diseases. When doctors test for cardiolipin antibodies, they look for different types, including IgM.
This article will explain everything you need to know about cardiolipin IgM antibodies: what causes them, what symptoms they produce, how they’re diagnosed, and what they might mean for your health.
