Lupus Anticoagulant is a kind of autoantibody that prevents blood clotting. It works against the phospholipid in the cell lining. This interferes with the process of blood clotting and leads to serious problems such as conditions of heart blockage and excessive clotting. The Lupus Anticoagulant Profile test is used to examine the causes of continuous blood clotting. It also analyses the reason for repeated miscarriages. This test is used with a few other examinations to diagnose problems like the APA syndrome, excessive clotting disorder, and others. It is performed as a regular blood test. The results are tested in the lab.
