Abstract
OBJECTIVES: The aim of this verification study was to compare the QuantiFERON-TB Gold Plus (QFT-Plus) to the QuantiFERON-TB Gold In Tube (QFT-GIT). The new QFT-Plus test contains an extra antigen tube which, according to the manufacturer additionally elicits a CD8 T-cell response above the CD4 T-cell response. We assessed the value of this tube in detecting recent latent tuberculosis infections.
