In October 2008, the Canadian Tuberculosis Committee released an Advisory Committee Statement, Updated Recommendations on Interferon Gamma Release Assays for Latent Tuberculosis Infection.

Two Interferon Gamma Release Assays (IGRAs) are licensed for use in Canada: Quantiferon TB Gold and T-SPOT TB. However, neither are presently covered under the Ontario Health Insurance Plan (OHIP).  As of June 2009, Quantiferon TB Gold testing can be obtained on a limited basis through Gamma-Dynacare Medical Laboratories. At the current time, the cost for this testing is approximately $90.00. Other commercial laboratories may also offer IGRA testing in the future.
