The key difference between mitogen and growth factor is that mitogen is a small protein that induces the cell to begin cell division, while growth factor is a naturally occurring substance that is capable of stimulating cell proliferation, wound healing, and cellular differentiation. Collect 1 mL (Min: 0.8 mL, Max 1.2 mL) of whole blood directly into each of the four tubes in the QuantiFERON-TB (High Altitude) 4 In-Tube Collection Kit. Cleveland Clinic Laboratories. (failure of the negative control), or lack of response to the mitogen (failure of the positive control). The TB antigen tube finding was interpreted if the values of nega - tive and positive control met the following criteria: nil <8.0 kIUl-1 and mitogen minus nil 0.50 kIUl . Most people with a positive TB blood test have latent TB infection. The mechanism of action of a mitogen is that it triggers signal transduction pathways involving mitogen-activated protein kinase (MAPK), leading to mitosis. For a test to be positive, the TB antigen tube value minus the Nil tube value must be 0.35 IU/mL. M. tuberculosis complex infection unlikely. .
