Evaluation of prolonged aPTT values in the pediatric population
WebUpper limit of normal Activated partial thromboplastin time (APTT) test result referent values is 45(s). APTT is a measure of one part of the clotting system known as the “intrinsic pathway”. A high activated partial thromboplastin time indicates that there is an abnormality with the clotting cascade. WebProlongation of the activated partial thromboplastin time (APTT) can occur as a result of deficiency of one or more coagulation factors (acquired or congenital in origin), or the presence of an inhibitor of coagulation such as heparin, a lupus anticoagulant, a nonspecific inhibitor such as a monoclonal immunoglobulin, or a specific coagulation factor inhibitor. WebPT: prothrombin time; aPTT: activated partial thromboplastin time; DIC: disseminated intravascular coagulation; HMW: high molecular weight. * In principle, many anticoagulants affect common pathway factors and can prolong both the PT and the aPTT if present at high enough levels.
