Lower than expected results with the Mitogen tube prevent false-negative Quantiferon readings by detecting a patient with a potential immune suppressive condition and/or suboptimal pre-analytical specimen handling. Create a PDF. local wrap = {}-- Holds wrapper functions that process arguments from #invoke. IFN-gamma-producing M tuberculosis specific CD8+ T cells have been detected in subjects with LTBI and in patients with active TB. Therefore, addition of the TB2 antigen tube in the Quantiferon TB Gold Plus test enables the detection of both active and latent tuberculosis, and it also aids in the diagnosis of TB infection in HIV positive patients with low CD4+ counts. Mitogen & 3.Nil Ag minus Nil: Positive >0.35 IU/mL Some experts call for a borderline zone up to 0.7 QFT Plus Tubes: 1. QuantiFERON-TB Gold In-Tube test for diagnosis of latent tuberculosis (TB) infection in solid organ transplant candidates: a single-center study in an area endemic for TB. The TB2 minus Nil value indicates interferon-gamma response of both CD4+ and CD8+ T lymphocytes, stimulated by the TB2 antigens. The NIL tube value indicates if the patient has an ongoing immune response which can cause a false-positive result. Clin Chem (1981) 27:493-501. QuantiFERON-TB Gold In-Tube (QFT) for the detection of LTBI in candidate for kidney transplantation. Sample results. My calculated value of 1.06 (TB antigen tube value minus the Nil tube value) can show a 52% reversion rate. The Mitogen minus Nil value serves as the positive control, demonstrating the successful responsiveness of the T lymphocytes in patient specimen. Low response may indicate inability to generate IFN-. The mitogen tube must have a gamma interferon value of greater than or equal to 0.5 IU/mL higher than the value of the Nil tube. We recruited twenty-three pulmonary TB patients and 34 household contacts from Cape Town, South Africa and performed the QFT test. .
