The mechanism of action of a mitogen is that it triggers signal transduction pathways involving mitogen-activated protein kinase (MAPK), leading to mitosis. elimination of tuberculosis (TB) in the United States. Repeat testing on a new specimen is suggested.

Quantiferon-TB Gold In-Tube Test (10010388) Test Mnemonic: QUANTIFERON-TB GOLD. IFN- concentrations greater than 10 IU/ml may be unreliable because of the limited linear range of the ELISA reader, and were therefore truncated at 10 IU/ml. For example, in 2019-2020, approximately 71% of children aged 1-17 years who were examined in the MEC provided a blood specimen through phlebotomy, while 94% of examined adults age 18 and older provided a blood specimen. B cells, on the other hand, divide to produce plasma cells when stimulated by mitogens, which then produce immunoglobulins, or antibodies.
