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

Published April 8, 2021

Key Messages

  • 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.
