Serial interferon-gamma release assays during treatment of active tuberculosis in young adults
BMC Infectious Diseases, 2010 Background The role of interferon-γ release assay (IGRA) in monitoring responses to anti-tuberculosis (TB) treatment is not clear. We evaluated the results of the QuantiFERON-TB Gold In-tube (QFT-GIT) assay over time during the anti-TB treatment of ...
