What is the lupus anticoagulant test?
Lupus anticoagulants are antibodies against substances in the lining of the cells. These substances prevent blood clotting, which is called phospholipids. People with antibodies to phospholipids may have a high risk of forming blood clots.

LAC test is not the first choice of the diagnostic test when patients present with these symptoms. ECG, venography, angiography, etc. are performed to diagnose blood clots. LAC test may be performed besides these tests.
LAC test is part of the routine examination in the prognosis of an autoimmune disorder by the name of the anti-phospholipid syndrome. It may be advised during pregnancy as well. Testing positive for LAC during pregnancy is a risk factor and requires constant medical supervision. The presence of LAC antibodies enhances the chances of blood clot formation that could lead to miscarriage. However, patients can test positive for LAC even in the complete absence of clot formation. Positive results should not be ignored, as they could have a fatal outcome.
