Making sense of agreement among interferon-gamma release assays and tuberculosis skin testing.

The international journal of tuberculosis and lung disease : the official journal of the International Union against Tuberculosis and Lung Disease, 2008
Numerous studies of interferon-gamma release assays (IGRAs) and tuberculin skin testing (TST) to assess latent tuberculosis infection have been published without a framework to understand the extent to which these two tests should agree. Analyzing the causes of variability in agreement levels is crucial.A mathematical model of agreement between ...

Interferon-gamma release assays during follow-up of tuberculin skin test-positive contacts.

The international journal of tuberculosis and lung disease : the official journal of the International Union against Tuberculosis and Lung Disease, 2009
Following a large-scale contact investigation, individuals with a positive tuberculin skin test (TST) result were offered preventive tuberculosis treatment.To investigate the effect of isoniazid (INH) treatment and the effect of time on interferon gamma release assay (IGRA) results during follow-up.TST-positive subjects (n = 122) detected during the ...

Interferon-gamma release assay test characteristics depend upon the prevalence of active tuberculosis.

The international journal of tuberculosis and lung disease : the official journal of the International Union against Tuberculosis and Lung Disease, 2010
Tuberculin skin tests (TSTs) may be negative in the absence of latent tuberculosis infection (LTBI) or in the presence of active tuberculosis (TB). The same phenomenon likely holds for interferon-gamma release assays (IGRAs).A mathematical model of LTBI test specificity was developed using elementary probability theory.
