QuantiFERON-TB Gold Plus (QFT-Plus) assay.
In this insightful episode, my focus is on the QuantiFERON-TB Gold Plus (QFT-Plus) assay developed by Qiagen. This innovative test, an upgrade from the QuantiFERON-TB Gold In-Tube assay, aims to improve TB detection by stimulating both CD4 and CD8 T cells. I discuss the significance of these cell types in TB control and the benefits of the QFT-Plus assay’s dual stimulation approach for enhanced sensitivity.
