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.

Comparative Evaluation of QuantiFERON-TB Gold In-Tube and QuantiFERON-TB Gold Plus in Diagnosis of Latent Tuberculosis Infection in Immunocompromised Patients [PDF]

Journal of Clinical Microbiology, 2018
QuantiFERON-TB Gold Plus (QFT-Plus) is a new-generation QuantiFERON-TB Gold In-Tube (QFT-GIT) assay which has two antigen-coated tubes called TB1, which contains long peptides derived from ESAT-6 and CFP-10, and TB2, which contains the same components as TB1 and additional short peptides which potentially stimulate CD8 +

Comparative Results of QuantiFERON-TB Gold In-Tube and QuantiFERON-TB Gold Plus Assays for Detection of Tuberculosis Infection in Clinical Samples

Journal of Clinical Microbiology, 2020
The QuantiFERON-TB Gold plus (QFT-Plus) assay, an interferon gamma (IFN-γ) release assay (IGRA), was recently introduced as the next version of the QuantiFERON-TB Gold In-Tube (QFT-GIT) assay for diagnosing latent tuberculosis (TB). Whereas the QFT-GIT assay uses only one TB tube that induces a cell-mediated immune (CMI) response of CD4

Resistance to Mycobacterium tuberculosis infection among highly TB exposed South African gold miners

PLoS ONE, 2022
Background Despite high exposure to Mycobacterium tuberculosis, a small proportion of South African goldminers resist TB infection. We determined, among long-service gold miners i) the proportion who were TB uninfected and ii) epidemiological factors ...

Utility of blood‐based Mycobacterium tuberculosis antigen‐specific host biomarkers in differentiating between spinal tuberculosis and mechanical back pain: A proof‐of‐concept study

Clinical and Translational Discovery, Volume 6, Issue 4, August 2026.
Spinal tuberculosis (TB) is a severe form of musculoskeletal TB whose diagnosis remains challenging and may be misinterpreted as mechanical back pain. Mycobacterium tuberculosis antigen‐specific host blood protein biomarkers detectable in QuantiFERON supernatants may offer greater specificity to distinguish spinal TB from mechanical back pain, with ...
