QuantiFERON® TB-Gold Plus

Note: Only available in scandinavia

QuantiFERON-TB Gold Plus (QFT-Plus) assesses the cell-mediated immune (CMI) response to TB-specific ESAT-6 and CFP-10 antigens through a quantitative measurement of IFN-γ in a whole blood sample.

QFT-Plus is an indirect test for M. tuberculosis infection (including disease) and is intended for use in conjunction with risk assessment, radiography, and other medical and diagnostic evaluations.

QFT-Plus uses exclusive TB-specific antigens that elicit CD4 and CD8 T-cell responses.

Testing with QFT-Plus is performed in two steps. First, whole blood samples are collected and exposed to the TB-specific or control antigens in the four custom QFT-Plus Blood Collection Tubes. Second, the production of IFN-γ in response to these antigens is measured using an enzyme-linked immunoassay (ELISA) or chemiluminescence immunoassay (CLIA).

QuantiFERON-TB Gold Plus is the first TB blood test to receive certification under the European Union’s new In Vitro Diagnostic Medical Devices Regulation (IVDR).
