First evaluation of QuantiFERON-TB Gold Plus performance in contact screening [PDF]

European Respiratory Journal, 2016
Identifying latently infected individuals is crucial for the elimination of tuberculosis (TB). We evaluated for the first time the performance of a new type of interferon-γ release assay, QuantiFERON-TB Plus (QFT-Plus), which includes an additional antigen tube (TB2), stimulating both CD4+and CD8+T-cells in contacts of TB patients.Contacts were ...

Comparing the performance of QuantiFERON-TB Gold Plus with QuantiFERON-TB Gold in-tube among highly TB exposed gold miners in South Africa [PDF]

Gates Open Research, 2021
Background: QuantiFERON-TB-Gold-in-tube (QFT-GIT) is an interferon-gamma release assay (IGRA) used to diagnose latent tuberculosis infection. Limited data exists on performance of QuantiFERON-TB Gold-Plus (QFT-Plus), a next generation of IGRA that includes an additional antigen tube 2 (TB2) while excluding TB7.7 from antigen tube 1 (TB1), to measure TB

Equal sensitivity of the new generation QuantiFERON-TB Gold plus in direct comparison with the presious test version QuantiFERON-TB Gold IT [PDF]

Pneumologie, 2016
QuantiFERON-TB Gold IT analyses interferon-γ release from CD4(+) T cells after stimulation with specific tuberculosis (TB) antigens. Its sensitivity is approximately 80% for active TB. A new test generation (QFTGplus) also analyses the response of CD8(+) T cells.
