QFT-Plus contains two TB-specific antigen tubes, called TB1 and TB2, for the incubation of the whole blood with Mtb antigens. The TB1 tube, contains long

2020-06-01 · QuantiFERON®-TB Gold Plus (QFT-Plus) offers two TB-specific antigen tubes (TB1 and TB2). TB1 elicits CD4 T-cell responses, and TB2 is designed to elicit both CD4 and CD8 T-cell responses. These mechanisms could be useful for estimating the role of CD8 T-cell immune responses to TB-specific antigens.

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). 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. The TB2 tube contains an additional set of peptides targeted to the induction of a CMI response from CD8+ cytotoxic T lymphocytes. 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.

TB inom bidragskalkylering där täckningsbidraget och täckningsgraden beräknas, är en förkortning av täckningsbidrag, alltså täckningsgraden uttryckt i summa. I små företag beräknas bara ett täckningsbidrag och en täckningsgrad, medans större företag kan använda sig av tre olika varianter. Following stimulation with TB1 and TB2, antigen-specific T-cells were characterized by flow cytometry.
