Of the 4 tubes, there are two (2) tubes that contain TB antigens. TB1 tube (green) measures interferon gamma released by CD4+ cells. TB2 tube (yellow) measures interferon gamma released by both CD4+ and CD8+ cells. Measurement of interferon gamma from both CD4+ and CD8+ cells enhances the overall sensitivity of the QFT assay.

Both the TB1 and TB2 tubes contain peptides from ESAT-6 and CFP-10 that are designed to elicit CMI responses from CD4+ T helper lymphocytes; TB Antigen Tube 2 (TB2) has an additional set of peptides targeted for the induction of CMI responses from CD8+ cytotoxic T lymphocytes. 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. Both antigen tubes include peptides from M. tuberculosis complex-specific antigens ESAT-6 and CFP-10. QFT-Plus contains two M. tuberculosis complex-specific antigen tubes, TB1 and TB2. TB1 contains ESAT-6- and CFP-10-derived long peptides designed to elicit cell-mediated immune responses from CD4 + T-helper lymphocytes; TB2 contains the same long peptides as TB1 in addition to shorter peptides able to stimulate CD8 T cells (6 – 8).
