The new IGRA, QuantiFERON-TB Plus (QFT-Plus), is based on the enzyme-linked immunosorbent assay detection of IFN-γ after stimulation with Mycobacterium tuberculosis TB1 and TB2 antigens. TB1 elicits a cellular-mediated immune (CMI) response by CD4 T cells, and TB2 contains peptides recognized by both CD4 and CD8 T cells. QFT-Plus employs two antigen tubes (TB1 and TB2) for diagnosis of M. tuberculosis infection. Per the manufacturer's recommendations, QFT-Plus is interpreted as positive when either antigen tube result is positive.

TB Antigen Tube 1 (TB1) and TB Antigen Tube 2 (TB2) both contain peptide antigens from the Mycobacterium tuberculosis (MTB)-complex-associated antigens ESAT-6 and CFP-10 and are designed to elicit a cell-mediated immunity (CMI) response from CD4+ T-helper lymphocytes.

TB1 and TB2 quantitative responses were not able to discriminate active disease from latent infection. The percent agreement between TB1 and TB2 was 100%. QFT-Plus assay showed good sensitivity for active TB and was particularly useful for the evaluation of children with suspected LTBI, giving a low rate of indeterminate results in this group. The new IGRA, QuantiFERON-TB Plus (QFT-Plus), is based on the enzyme-linked immunosorbent assay detection of IFN-γ after stimulation with Mycobacterium tuberculosis TB1 and TB2 antigens.

The TB1-NIL tube specifically detects CD4+ lymphocyte reactivity, specifically stimulated by the TB1 antigens. The TB2-NIL tube detects both CD4+ and CD8+ lymphocyte reactivity, stimulated by TB2 antigens. An overall Negative result does not completely rule out TB infection.
