Quantiferon-TB Gold Plus (QFT-Plus)

This month, we showcase Quantiferon-TB Gold Plus (QFT-Plus). QFT-Plus is an in vitro diagnostic test using a peptide cocktail stimulating ESAT-6 and CFP-10 proteins to stimulate cells in heparinized whole blood. Detection of interferon-g (IFN-g) by enzyme-linked immunosorbent assay (ELISA) is used to identify in vitro responses to those peptide antigens that are associated with Mycobacterium tuberculosis infection. 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.
