From Dr. King: We are encountering with increasing frequency requests from hematologists to perform mixing studies on patients that are known to be on some form of anticoagulation. My question is regarding the utility of doing such testing. Another aspect to the question is whether you can do testing for a prolonged PTT when the patient is known to be on warfarin or evaluate a prolonged PT in ...

An isolated prolonged aPTT result with a normal prothrombin time implies either the presence of heparin and inhibitor (either specific factor or lupus anticoagulant) or a factor deficiency of the intrinsic system. 7 Unless the cause for the prolonged aPTT is known, as in the case of heparin therapy, mixing studies may be necessary to determine the etiology of the prolonged result.

On adding the normal plasma in a 50:50 volume mix and repeating the aPTT, the test is verified because the deficient coagulation factor level is brought up to more than 30%, which is adequate to normalize the aPTT.1 If an inhibitor to a coagulation factor was present, the mixing tests will not correct the ...
