Anti Phospholipid Antibody, IgA

The AntiPhospholipid Antibody IgA test is used to study the antiphospholipid antibodies. These antibodies are found in people with antiphospholipid antibody syndrome, where the immune system makes antibodies that attack the body’s cells. People with abnormal blood clots or autoimmune diseases, such as lupus and multiple sclerosis, or women who have had repeated miscarriages have these antibodies.

A blood sample is collected for this test, which does not have many risks. It is important to inform your doctor about any medications you take before the test. If antiphospholipid antibody syndrome is detected, then blood-clotting medications are prescribed. High levels of antibodies could mean a high risk of blood clots. A second test is required after 12 weeks to confirm the results.
