The name derives from their properties in vitro, since in lab tests la causes an increase in clotting time. Read more...
Lupus anticoagualant. Is a tricky area. Patients with autoimmune diseases including lupus can present with a prolonged partial thromboplastin time (PTT) which would usually indicate an anticoagulant effect and risk for bleeding. Paradoxically, such individuals are at increased risk of clotting. Read more...

Lupus anticoagulants. Lupus anticoagulant is one of the tests used to diagnose a condition called anti phospholipid syndrome, a coagulopathy that increases the risk of venous thrombotic and arterial events. The presence of the lupus anticoagulant by itself is not diagnostic of aps. It should be taken in the context of clinical signs and symptoms and repeated at least twice (in addition to other test) within 12 weeks. Read more...
