Blood test measuring T-cell interferon-γ release for tuberculosis diagnosis.
Last updated
An interferon-γ release assay (IGRA) is a medical test for diagnosing infectious diseases, particularly tuberculosis. It measures interferon-γ released by T-lymphocytes when exposed to specific antigens. Two IGRA formats are available: QuantiFERON-TB Gold and T-SPOT.TB. The test has also been evaluated for latent tuberculosis in HIV patients.
