Introduction In Hong Kong, tuberculin skin test (TST) with a 15 mm cut-off was used at 0 and 3 months for contact screening, but half of future tuberculosis cases might be missed. Follow-on interferon ...

This study assessed the prevalence of LTBI in PLWH using the interferon-gamma release assay (IGRA) and the impact of the 3HP regimen (isoniazid [INH]/rifapentine [RPT]) as prophylactic treatment.

Each patient was screened with a tuberculin skin test (TST) and one form of an interferon-γ release assay (IGRA), either TSPOT.TB (TSPOT) or Quantiferon TB Gold (QFT). Results A total of 1529 patients ...

However, current diagnostic tools, such as interferon-gamma release assays (IGRAs) and tuberculin skin tests (TSTs ... Using this refined feature set, we identified IGRA/TST + contacts whose blood ...

SARS-CoV-2 triggers the production of the antiviral protein IFN-γ, which is associated with fatigue, muscle ache and depression. New research shows that in Long COVID patients, IFN-y production ...

Whether a CSF-based TBM host response assay could be developed (similar to the blood-based and Xpert MTB Host Response 3-gene assay) is uncertain. Further, transcriptomic technology may provide ...

In the present study we employed microfabricated surfaces to capture T-cells from minimally processed human blood, arrange these cells into a single cell array, and then detect interferon (IFN)-γ ...

In the present follow-up study, we investigated the effect of the addition of Mycobacterium leprae antigens on interferon-gamma (IFN-γ ... The detection limit of the assays was 8 pg/mL for both IFN-γ ...
