Technical interpretation of coagulation inhibitor testing to the specific factor requested, primarily factor IX in patients with hemophilia B
If the factor IX activity assay is normal or elevated, then a computer-generated interpretive comment will be provided indicating inhibitor testing is not indicated and will not be performed.
Only orderable as part of a profile. For more information see 9INHE / Factor IX Inhibitor Evaluation, Plasma.

Factor IX inhibitors arise in patients with severe hemophilia B after factor IX transfusion. Patients with factor IX inhibitors may also develop anaphylactic reactions in response to factor IX infusions. Acquired factor IX inhibitors, occurring in previously healthy people, are exceedingly rare.
Only orderable as part of a profile. For more information see 9INHE / Factor IX Inhibitor Evaluation, Plasma.
An interpretive report will be provided.
Occasionally, a potent lupus-like anticoagulant may cause false-positive testing for a specific factor inhibitor (eg, factor VIII or IX).
