Abstract

Specific coagulation factor inhibitors, most notably to coagulation factor VIII, can develop in patients with hemophilia after exposure to replacement factor or as an acquired (autoimmune) event. Such inhibitors can be detected by a combination of prolonged coagulation screening tests, such as the activated partial thromboplastin time, plus a non-correcting mixing test. Non-correction may only be evident, or else may be extenuated, with incubation at 37 °C. The Bethesda assay for quantitation of inhibitor strength is based on a combination of mixing tests followed by specific factor assays.
