The "Gold-standard" was considered by the combination of culture results and clinical diagnosis. Respiratory tuberculosis was present in 9.7% (127 patients), and non-respiratory tuberculosis was present in 18.9% (170 patients, mostly originated from Africa). Among the 2427 respiratory samples (197...

Even in industrialized countries, the triad of a positive tuberculin skin test, radiographic and/or clinical manifestations consistent with tuberculosis, and establishing a recent link to a known infectious case of tuberculosis is the "gold standard" for diagnosis. Children with tuberculosis respond ...
To assess the prevalence of disseminated TB, MTB blood culture positivity was considered the gold-standard test, and the analysis was restricted to: 1. patients with at least one mycobacterial blood culture result (n = 410), to determine prevalence amongst HIV-inpatients; and 2. patients...
Because of the lack of a gold standard for the diagnosis of LTBI, IGRAs are compared to the tuberculin skin test () and yield conflicting results. We assessed the usefulness of an IGRA test, QuantiFERON()-TB Gold In-Tube (QFT-G-IT), for diagnosing LTBI compared with in the setting of...

Because of the lack of a gold standard test that accurately identifies subjects without LTBI, many investigators have evaluated only the sensitivity of the IGRAs either in culture proven or using combined results of culture and clinical findings as gold reference [14, 20, 35]. In the present st...
Guidelines for using the QuantiFERON-TB Gold test for detecting Mycobacterium tuberculosis infection, United States. On May 2, 2005, a new in vitro test, QuantiFERON-TB Gold (QFT-G, Cellestis Limited, Carnegie, Victoria, Australia), received final approval from the U.S. F... GH Mazurek,...
Basically, the sensitivity of the test depends on the host cellular immunity, and therefore false-negative results are seen in cases of immunosuppression or active TB infection. The antigens included in the purified protein derivative (PPD) are shared by other mycobacteria, and thus specificity of...
