Cardiolipin Antibody (IgM)
Also known as: Phospholipid Antibody, IgM, Anti-Cardiolipin IgM
Use
Cardiolipin antibodies (CA), specifically of the IgM isotype, are associated with autoimmune disorders—especially systemic lupus erythematosus—and are linked to risks such as vascular thrombosis, thrombocytopenia, cerebral infarct, and recurrent spontaneous abortion. Elevated IgM cardiolipin antibody levels may also be observed in idiopathic thrombocytopenic purpura, rheumatoid and psoriatic arthritis, and primary Sjögren’s syndrome.
