50391-2
LaboratoryCoag.Surface induced circulating inhibitor [Presence] in Platelet poor plasma by Coagulation assay
Definition
PTT (aPTT) circulating inhibitor is part of the PTT mixing study. When addition of normal plasma fails to correct the clotting time into the normal range, the cause of the abnormal test is likely an inhibitor rather than a clotting factor deficiency.
