Interferon Gamma Release Assay for the Identification of Latent Tuberculosis Infection in Rural and Remote Settings

There is a lack of evidence on the clinical utility of the interferon gamma release assay for identifying latent tuberculosis infection in rural and remote settings. In remote Indigenous communities with known history of bacillus Calmette-Guérin vaccination, more positive tests results were reported with the tuberculin skin test than with the interferon gamma release assay.
