We describe here a test for lupus anticoagulants based on a modified Russell viper venom time (RVVT). using limiting amounts of phospholipid and venom. We have studied 29 patients with a prolonged dilute RVVT. Five of the 29 had a normal activated partial thromboplastin time and three of 1 4 tested by the tissue thromboplastin inhibition test were normal. In 1 7 of 1 9 patients tested. the dilu...

● Context.—Fondaparinux, a factor Xa inhibitor, is approved for thromboprophylaxis after orthopedic surgery and for treatment of venous thromboembolism.

The effect of fondaparinux on coagulation testing needs to be thoroughly examined. Objective.—To report the effects of...

CONTEXT Preanalytical factors influencing the reliability of laboratory testing are commonplace. It is traditionally accepted that hemolytic samples are unsuitable for coagulation assays because of the release of hemoglobin, intracellular components, and thromboplastic substances from damaged blood cells. OBJECTIVE To evaluate the influence of blood cell lysis on routine coagulation testing. ...
