- there is no agreement as to which group of tests is more sensitive to measure lupus erythematosus anticoagulant;
- plasma showing abnormal activated partial prothrombin time, a positive screening test for lupus anticoagulant, & no evidence of fibrin-fibrinogen degradation products is considered positive for lupus erythematosus anticoagulant;
