Newly developed assays that measure the production of cellular interferon gamma are
useful diagnostic tools for the diagnosis of tuberculosis and may potentially replace or …

Rationale: Interferon (IFN)-γ blood tests may improve the current level of diagnostic accuracy
for tuberculosis infection. The QuantiFERON-TB Gold (QFT-Gold) has been used in selected …

The sensitivity of an interferon-γ assay (Quantiferon-TB Gold; Cellestis) was evaluated for
the detection of tuberculosis among 242 persons with suspected tuberculosis in San …

Sputum smears for acid-fast bacilli (AFB) are the primary methods for diagnosis of
tuberculosis (TB) in many countries. The tuberculin skin test (TST) is the primary method for …

Setting: Victoria, Australia. OBJECTIVE: To determine the sensitivity and specificity of a
gamma interferon (IFN-γ) blood test for tuberculosis infection. Design: Heparinised blood …

PURPOSE: To assess the utility of interferon γ levels, including identification of the best
cutoff for the diagnosis of tuberculosis. METHODS: We prospectively studied consecutive …

The gamma interferon secretion levels of 52 adults whose T cells had been stimulated with
the Mycobacterium tuberculosis antigens CFP-10 and ESAT-6 were measured by enzyme …

ContextIdentifying persons with latent tuberculosis infection (LTBI) is crucial to the goal of TB
elimination. A whole-blood interferon γ (IFN-γ) assay, the QuantiFERON-TB test, is a …

A whole-blood interferon-γ release assay (IGRA) is being evaluated for its potential to
replace the tuberculin skin test (TST) for detecting Mycobacterium tuberculosis infection. To …
