Significant decrease of IFN-γ response to antigen present in QFT-Plus test in LTBI subjects We evaluated the results also by quantitative means (Fig.1A). In LTBI we found that the median of TB1 response (4.6 IU/mL, IQR: 1.3–10) at baseline was significantly higher than that observed ...
*Purpose: QuantiFERON-TB (QFT) is the preferred diagnostic test for latent tuberculosis infection (LTBI). The QFT-Gold Plus (QFT-Plus) data in OLT candidates is limited.*Methods: Our hospital replaced QFT-Gold In-Tube (QFT-GIT) with QFT-Plus in 3/2019. We assessed QFT-Plus ...
QuantiFERON-TB Gold Plus: Results and Interpretation When it comes to result calculation, qualitative cutoff values, and result interpretation, the QFT-Plus is identical to the QFT-Gold assay, with the key exception that if either one or both of the QFT-Plus TB antigen tubes are equal to or...
In view of the newQuantiFERON-TB Plus test, including tuberculosis specific antigens that elicits interferon-γ release by CD8+T lymphocytes in addition to CD4+T cells, further studies will be necessary to understand if our results are applicable also to the new test and to estimate its sensit...
