Repeat testing or additional tuberculin skin tests for management of indeterminate results of interferon-gamma release assays: a systematic review and meta-analysis. [PDF]

BMC Infect Dis
Background Interferon-gamma release assays (IGRAs) are widely used for detecting latent tuberculosis infection (LTBI). However, these tests can yield indeterminate results, posing challenges for clinical management.
