Negative anticardiolipin antibodies are normal, while a positive test indicates antiphospholipid antibody syndrome or other immune disorders. Antiphospholipid antibody syndrome is an immune disease caused by antiphospholipid antibodies, mainly manifested by arterial and venous thrombosis, recurrent spontaneous abortion and thrombocytopenia, etc. Anti-cardiolipin antibodies, β2-glycoprotein antibodies, and lupus anticoagulant are positive in the examination of immune markers. This disease is an autoimmune disease that is difficult to cure. Generally, normal people have negative results for anticardiolipin antibodies, while other immune diseases such as systemic lupus erythematosus may also show positive anticardiolipin antibodies. If you develop positive anticardiolipin antibodies, you will need to seek further medical attention and treatment as prescribed by your doctor.
