Used to test patients in over 130 countries, the fourth generation QuantiFERON®-TB Gold Plus assay identifies interferon-gamma released by T-cells following recognition of TB specific antigens as a marker of TB infection. Interferon gamma release assays (IGRA) require only one patient visit to a healthcare provider and are more accurate than the traditional two-visit skin test that has been used for over a century to detect the latent form of the infection.
