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 ...
