Term Description

The quantitative levels (uncorrected for background) for an IFN-gamma response by CD4+ T-helper and CD8+ T cytotoxic lymphocytes stimulated by the presence of TB antigens, specifically ESAT-6 and CFP-10. This term was created for, but not limited in use to, the QuantiFERON-TB Gold Plus test, which includes two tubes with the Mycobacterium tuberculosis (MTB)-complex-associated antigens ESAT-6 and CFP-10 that stimulate a cell-mediated immunity (CMI) response. The first tube contains antigens that stimulate a response from CD4+ T-helper lymphocytes [LOINC: 64084-7], and the second tube (this term) contains the antigens included in tube 1 as well as an additional set of peptides targeting the CMI response from CD8+ cytotoxic T lymphocytes. In the QuantiFERON-TB Gold Plus test, the amount of IFN-gamma is measured by enzyme-linked immunosorbent assay and reported in IU/mL. Results are adjusted for background, heterophile antibody effects, or nonspecific IFN-gamma in blood samples.
