Indicator Explainer
Interferon Alpha
A class of interferon (leukocyte interferon) produced predominantly by B lymphocytes. Located in a cluster on 9p22 there are at least 13 functional genes and 1 pseudogene.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
