A mitogen is a small bioactive protein or peptide that induces a cell to begin cell division, or enhances the rate of division ( mitosis ). The Nil result is a measure of the background level of gamma interferon in the specimen. QuantiFERON-TB Gold (QFT) is a simple blood test. The MITOGEN-NIL value serves as the positive control for the patient specimen, demonstrating successful lymphocyte activity. Lymphocyte proliferation in response to these mitogens and antigens is determined by 3 H-thymidine incorporation. Normal sperm densities range from 15 million to greater than 200 million sperm per milliliter of semen.
