TB infection is different from active TB disease; and a flare up could happen within weeks of acquiring the infection or maybe years ...

Tulane University researchers have developed a new handheld TB test that significantly improves detection in people with HIV, ...

When tested against the traditional IGRA blood test (Interferon-Gamma Release Assay), the ASTRA detected TB in HIV-infected individuals with 87% specificity compared to IGRA's 60%, while also ...

Follow-on interferon-gamma release assay (IGRA) was added for those with tuberculin reaction of 5–14 mm in a pilot programme. Methods This was a prospective cohort study.

Background: The utility of interferon gamma release assays (IGRAs) has been assessed in adults, but remains unclear in children. We reviewed the literature on the use of a commercial IGRA in ...

Table 1 Interferon gamma release assay (IGRA) for latent tuberculosis infection among 335 people living with HIV-1, from December 2021 to September 2024.

A University of Cambridge-led study identifies the protein interferon gamma (IFN- γ) as a potential biomarker for Long COVID fatigue and highlights an immunological mechanism underlying the ...

Objective To compare the interferon-gamma-release assay (IGRA – QuantiFERON ® TB Gold In-Tube) with the tuberculin skin test (TST – PPD-Rt 23) for latent tuberculosis infection (LTBI) in patients with ...

Interferon Gamma Release Assay (IGRA) Blood was collected from each participant using all aseptic precautions in a unique tube coated with a cocktail of tubercular antigens.

Interferon-gamma release assays (IGRA) are blood tests used to identify people with TB infection. IGRA tests cannot discriminate between latent and active TB. Furthermore, false negatives can occur in ...

BACKGROUND An ‘indeterminate’ interferon-gamma release assay (IGRA) result used in the diagnosis of latent TB infection (LTBI) is most commonly due to an inadequate control (or ‘mitogen’) response, ...
