An autoimmune disease can be defined as the phenomenon by which our body generates antibodies that attack its own tissues resulting in destruction and deterioration of those tissues. Anticardiolipin antibodies can be found in people with antiphospholipid antibody syndrome. ACA can often be observed during the convalescent phase of acute bacterial and viral infections. Cardiolipin is a phospholipid or a kind of fat in the blood. The test is ordered for people who have symptoms suggestive of abnormal blood clotting, repeated miscarriages. This test looks for a certain kind of antibody in your blood. The lab report generated after the test will give you the standard value range for your age group and gender.
