Tuberculosis Interferon-Gamma Release Assay (IGRA)
Interferon-gamma release assay for Mycobacterium tuberculosis infection. Unlike the tuberculin skin test, IGRA is not confounded by prior BCG vaccination, and requires only a single visit. It cannot distinguish latent from active infection on its own.
