Term Description

This term is created for but not restricted in use to a Nijmegen modification of the classic Bethesda inhibitor titration assay using a chromogenic method. The use of a chromogenic method allows factor VIII inhibitor to be detected in patients receiving emicizumab / Hemlibra®, a therapeutic that interferes with standard clot-based methods PMID: 29446525.

Part Descriptions

LP29023-6   Coagulation factor VIII inhibitor
Factor VIII replacement is the foundational treatment for hemophilia A, and the developement of alloantibodies (known as inhibitors) against the replacement factor is the most important complication causing morbidity in hemophilia patients. Antibodies against factor VIII can be inhibitory or noninhibitory, with inhibitors generally being polycloncal IgG directed against the A2, A3 and C2 domains of the factor VIII molecule. The resulting steric hindrance can block functional epitopes including FIX, phospholipid, or von Willebrand binding sites PMID: 23610614. Source: Regenstrief LOINC

LP14587-7   Factor VIII
Blood-coagulation factor VIII; Antihemophilic factor that is part of the factor VIII/von Willebrand factor complex. Factor VIII is produced in the liver and acts in the intrinsic pathway of blood coagulation. It serves as a cofactor in factor X activation and this action is markedly enhanced by small amounts of thrombin. Source: National Library of Medicine, MeSH 2006
