Anti Cardiolipin Antibodies Igg, Serum

More information

Anti-Cardiolipin antibodies are autoantibodies that target cardiolipin, a lipid component found in cell membranes. Elevated levels of these antibodies, particularly IgM or IgG, are associated with antiphospholipid syndrome (APS), an autoimmune disorder that increases the risk of abnormal blood clotting, recurrent miscarriages, and other complications. The presence of these antibodies can lead to the formation of clots in veins and arteries. Testing for anti-cardiolipin antibodies helps diagnose APS, guide treatment decisions, and monitor disease activity. This test is often used in conjunction with other diagnostic tools to assess and manage clotting disorders.
