Comparison of LIAISON QuantiFERON-TB Gold Plus with QuantiFERON-TB Gold Plus [PDF]
Microbiology Spectrum, 2023 Abstract With the large global burden of latent tuberculosis (TB) infection (LTBI), screening for LTBI for various reasons has become standard practice including the low-prevalence settings. The results showed acceptable intra- and inter-run precision as well as cutoff verification across the two analyzers at the afore ...

Identification of Recent Tuberculosis Exposure Using QuantiFERON-TB Gold Plus, a Multicenter Study [PDF]
Microbiology Spectrum, 2021 We investigated whether the difference of antigen tube 2 (TB2) minus antigen tube 1 (TB1) (TB2−TB1) of the QuantiFERON-TB gold plus test, which has been postulated as a surrogate for the CD8+ T-cell response, could be useful in identifying recent ...

QuantiFERON-TB Gold Plus and QuantiFERON-TB Gold In-tube assays for detecting latent tuberculosis infection in Thai healthcare workers [PDF]
Revista do Instituto de Medicina Tropical de São Paulo, 2023 Detecting latent tuberculosis infection (LTBI) is important, especially in high-risk populations including healthcare workers (HCWs). QuantiFERON-TB Gold Plus (QFT-Plus) is a new version of the interferon-gamma release assays (IGRAs) to replace the QuantiFERON-TB Gold In-tube (QFT-GIT). However, data on the use of QFT-Plus for LTBI detection in high TB-
