Interferon-gamma-release assays: Better than tuberculin skin testing?
Although the tuberculin skin test has long been the standard for detecting latent tuberculosis infection, it has many limitations. Interferon-gamma-release assays are gaining acceptance as an alternative. In this paper we present cases to illustrate how these new tests can be used and how to interpret the results.
متن کاملTuberculin Skin Tests versus Interferon-Gamma Release Assays in Tuberculosis Screening among Immigrant Visa Applicants
Objective. Use of tuberculin skin tests (TSTs) and interferon gamma release assays (IGRAs) as part of tuberculosis (TB) screening among immigrants from high TB-burden countries has not been fully evaluated. Methods. Prevalence of Mycobacterium tuberculosis infection (MTBI) based on TST, or the QuantiFERON-TB Gold test (QFT-G), was determined among immigrant applicants in Vietnam bound for the U...

متن کاملComparing Interferon-Gamma Release Assays to Tuberculin Skin Test in Thai Children with Tuberculosis Exposure
BACKGROUND Data on the performance of interferon-gamma release assays (IGRAs), QuantiFERON TB Gold In-tube (QFNGIT) and T-Spot.TB, in diagnosing tuberculosis (TB) are limited in Southeast Asia. This study aims to compare the performances of the two IGRAs and TST in Thai children with recent TB exposure. METHODS This multicenter, prospective study enrolled children with recent exposure to acti...
متن کاملTB Screening in Canadian Health Care Workers Using Interferon-Gamma Release Assays
BACKGROUND While many North American healthcare institutions are switching from Tuberculin Skin Test (TST) to Interferon-gamma release assays (IGRAs), there is relatively limited data on association between occupational tuberculosis (TB) risk factors and test positivity and/or patterns of test discordance. METHODS We recruited a cohort of Canadian health care workers (HCWs) in Montreal, and p...
