$790.00. Nil (grey cap), TB1 antigen (green cap), TB2 antigen (yellow cap) Mitogen (purple cap) Tb-Quantiferon Gold specific tube sets: How to obtain tubes for customers both inside and outside the Auckland region Internal Contact Lablink x22000 Lablink is staffed for these requests Monday - Friday: 8am - 3.30pm (Mitogen), eine Negativkontrolle (Nil) und zwei eigentliche Tbc-Teströhrchen (TB1 und TB2). Die Antigene in den Tbc-Teströhrchen TB1 und TB2 (u.a. ESAT-6 und CFP-10) stimulieren die Ausschüttung von IFN-γ durch T-Lymphozyten, sofern der Patient bereits früher in seinem Leben Kontakt zu M. tuberculosis Komplex hatte. Taking it step by step, first evaluate the Nil and the mitogen result and then the results of the TB1 and TB2. Significance of the NIL result : The NIL indicates the presence of any residual interferon-γ found in the patient’s blood due to an infection with an organism requiring cell mediated immunity/T cell immunity (e.g. virus, fungus, intracellular bacteria, etc.). The MITOGEN-NIL value serves as the positive control for the patient specimen, demonstrating successful lymphocyte activity.

ELISA for  22 Jan 2020 4 h: a Nil tube, TB tube, and a Mitogen tube for QFT-GIT or Nil tube, TB1 tube, TB2 tube, and. 120. Mitogen tube for GFT-Plus. The Mitogen tube  QFT-Plus was considered positive if either antigen tube 1 (TB1) or TB2 tested positive, per QFT-Plus TB1, QFT-Plus TB2, QFT TB Antigen, and QFT TB Mitogen. For QFT, the results are considered positive when the TB Antigen minus Ni The nil tube value is subtracted from the values of the mitogen, TB1, and TB2 tubes for the final result of the respective tubes.

Taking it step by step, first evaluate the Nil and the mitogen result and then the results of the TB1 and TB2. Significance of the NIL result: The NIL indicates the presence of any residual interferon-γ found in the patient’s blood due to an infection with an organism requiring cell mediated immunity/T cell immunity (e.g. virus, fungus, intracellular bacteria, etc.). MITOGEN-NIL >10.00 IU/mL TB1-NIL 0.00 IU/mL TB2-NIL 0.01 IU/mL The Nil tube value reflects the background interferon gamma immune response of the patient's blood sample.

Two of the 4 collection tubes contain antigens representing certain Mycobacterium tuberculosis proteins and 2 of the tubes are controls (Nil and mitogen). 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.

Label tubes appropriately. Ensure each tube (Nil, TB1, TB2, & Mitogen) is identifiable by its label or other means (once the cap has been removed the label identifies each tube.) 5.

The QFT-Plus assay has 2 distinct TB antigen tubes: TB Antigen Tube 1 (TB1) and TB However, the TB2 tube also contains an additional set of ESAT-6 and CFP-10 Indeterminate results due to a low IFN-gamma level in the mitogen ( posi M. tuberculosis infection is NOT likely.

The QFT-Plus Mitogen tube contains phytohemagglutinin that stimulates T-cells and the production of IFN-γ. The QFT-Plus Nil tube contains no antigens and is used to adjust for pre-existing IFN-γ (i.e., The IFN-γ level of the Nil tube sample is subtracted from the IFN-γ levels of the TB1, TB2, and Mitogen tube samples).

The TB2-NIL tube detects both CD4+ and CD8+ lymphocyte reactivity, stimulated by TB2 antigens. 2018-01-22 · Nil TB1 ‐Nil TB2 ‐Nil Mitogen ‐Nil QualitativeResult Interpretation ≤8.0 IU/mL ≥0.35 and ≥25% of Nil Any Any Positive M.tuberculosis infection likely Any ≥0.35 IU/mLand ≥25% of Nil <0.35 IU/mL OR ≥0.35 IU/mL and <25% of Nil ≥0.5 IU/mL Negative M.tuberculosis infection NOT likely <0.5 IU/mL Indeterminate 2021-01-27 · The 4 collection tubes must be at 17-25°C at the time of blood filling. Collect 1 mL in each tube: [one NIL (Grey top), one TB1 Ag (Green top), one TB2 Ag (Yellow top), one MIT (Lavender top)].
