Recommendations on Interferon Gamma Release Assaysfor the Diagnosis of Latent Tuberculosis Infection—2010 Update

release assays being published all the time, the field is quickly evolving.As a result, this Advisory Committee Statement will be periodically updated as warranted and made available at www.publichealth.gc.ca/tuberculosis.Although no formal grading of the quality of evidence was done, almost all the available studies on IGRAs have limitations, namely lack of a gold standard for latent TB sur les tests de libération d'interféron-gamma étant constamment publiés.La présente déclaration d'un comité consultatif sera donc périodiquement mise à jour au besoin et sera affichée à l'adresse www.santepublique.gc.ca/tuberculose.• Alberta Health and Wellness, Disease Control and Prevention Branch• Division of Tuberculosis Control, British Columbia Centre for Disease Control • Manitoba Tuberculosis Control Program
