Interferon-gamma release assay for screening of tuberculosis infection in children [PDF]

BMC Infectious Diseases, 2023
Background Interferon-gamma release assay (IGRA) is the main tool for the diagnosis of latent tuberculosis (TB) infection (LTBI). However, the indeterminate results were more frequent in children, and the underlying reasons were largely speculative.

Interferon-gamma release assay performance in pulmonary and extrapulmonary tuberculosis. [PDF]

PLoS ONE, 2012
The diagnosis of tuberculosis remains difficult. This study aimed to assess performance of interferon-gamma release assay (IGRA) in diagnosis of active tuberculosis (ATB) with pulmonary and extrapulmonary involvements, and to determine the diagnostic ...

Interferon-gamma release assay positivity in populations at high risk of TB infection [PDF]

IJTLD Open
BACKGROUND: Phase 3 TB vaccine trials are challenging in low-incidence settings due to the need for large sample sizes and extended follow-up. This global, observational study evaluated population-based interferon-gamma release assay (IGRA) status – a ...

Evaluation of SARS-CoV-2 interferon gamma release assay in BNT162b2 vaccinated healthcare workers [PDF]

PLoS ONE
To predict protective immunity to SARS-CoV-2, cellular immunity seems to be more sensitive than humoral immunity. Through an Interferon-Gamma (IFN-γ) Release Assay (IGRA), we show that, despite a marked decrease in total antibodies, 94.3% of 123 ...

Miliary Tuberculosis with Indeterminate Interferon Gamma Release Assay Results

Internal Medicine, 2013
Recently, interferon gamma release assays (IGRAs) have become an important clinical tool for detecting latent tuberculosis. However, IGRA results may impede making a diagnosis. We herein present an interesting case of miliary tuberculosis with a nonspecific IGRA reaction due to hemophagocytosis.

The Benefit of Interferon-Gamma Release Assay for Diagnosis of Extrapulmonary Tuberculosis

Acta Medica Indonesiana, 2018
Background: there are many researches about IGRA in extrapulmonary Tuberculosis (TB), but there only few data from developing countries. This was the first research about the utility of IGRA in extrapulmonary TB performed in Indonesia as developing ...

Novel approach to activity evaluation for release-active forms of anti-interferon-gamma antibodies based on enzyme-linked immunoassay. [PDF]

PLoS ONE, 2014
Selection of a suitable assay to measure the activity of drug agents based on release-active forms of anti-interferon-gamma antibodies (RA forms of Abs) is an important step forward in the investigation of such agents.

Interferon-gamma release assay: use and misuse [PDF]

Clinical Microbiology and Infection, 2012
Interferon-gamma release assays are being increasingly used worldwide for the diagnosis of latent tuberculosis (TB) in patients of all ages, including children [1]. A PubMed search with ‘interferon-gamma release assays’ as keyword revealed a total of 1077 references, up to 100 of which had been released in 2012, including several reviews.
