Order Code: 1138 Get Requisition Form
Test Information Icon
Test Information
The chromogenic factor VIII inhibitor assay uses bovine reagents, is insensitive to emicizumab and lupus anticoagulant, and is adversely affected by the presence of direct factor X inhibitors or very high concentrations of heparin (greater than 2 U/mL). The addition of hepzyme in this assay will neutralize the influence of heparin.
