WebWhat is PTT lupus anticoagulant? PTT usually measures the time taken for the blood to clot. It can also reveal the presence of LAC in the blood. A lupus anticoagulant-sensitive activated partial prothrombin test (aPTT) is a type of PTT test which is sensitive to the lupus anticoagulant antibodies and shows more accurate values of LAC. Webvaried owing to their different sensitivity to the coagulation defect induced by VKA. Consequently, PT results obtained for the same patient cannot be compared across laborato-ries. Furthermore, the ‘universal’ therapeutic interval stem-ming from clinical trials cannot be applied to individual patients. To minimize the between ...
WebThe PTT-LA is a sensitive, but nonspecific screening test for LA. It may be prolonged if the patient is on anticoagulant therapy (ie, heparin, warfarin, or thrombin inhibitors). If the patient is not anticoagulated and the result is ≤ 50 sec then you may want to consider an aPTT with a routine reagent.
