The normal range of anticardiolipin antibody IgG is around 0 to 12 GPL/ml, so it is normal to say that anticardiolipin antibody IgG 9.93 GPL/ml. Anti-cardiolipin antibody is a kind of autoantibody produced by taking the negatively charged cardiolipin on the cell membrane of platelets and endothelial cells as the target antigen, which is mainly seen in some immune system diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and scleroderma and other diseases. The normal range of anticardiolipin antibody IgG detected by ELISA kit is around 0~12GPL/ml, if it exceeds the normal value, it is anticardiolipin antibody positive in the medical point of view, and anticardiolipin antibody positivity is often found in patients with antiphospholipid antibody syndrome. Antiphospholipid antibody syndrome is often characterized by venous or arterial thrombosis, recurrent miscarriages in some patients, and a persistent drop in platelets on routine blood tests. Thrombosis is treated with anticoagulation with aspirin or warfarin. If the patient has a history of miscarriage, or if there have been more than three miscarriages, aspirin and heparin should be used throughout the pregnancy. If thrombocytopenia is severe, it can be treated with prednisone combined with immunoglobulin intravenously. In case of abnormal results of anticardiolipin antibody IgG test, it is recommended to consult a doctor for diagnosis and symptomatic treatment.
