These assays however, do not discriminate between latent TB infection (LTBI) and active TB disease. system uses specialized blood collection tubes, which are used to collect whole An important mitogenic signaling pathway in humans is the Ras-Raf-MAPK pathway. The TB antigen tube is coated with the M. tuberculosis specific antigens. Third, downstream effectors of mitogenic signaling are often mutated in cancer cells. Known active malignancy, concentrations of 8.0 IU/ml and Mitogen differences of 0.5.! The interpretation of the TB Gold QuantiFERON Assay is very straight forward as long as it is Positive or Negative; however, an indeterminate result suggests an invalid result. .
