WebMar 30, 2024 · How do interferons work? The cells of our immune system have different functions. For example, some immune cells, e.g. natural killer cells and macrophages, kill germs or cancer cells. Other immune cells, such as B lymphocytes produce antibodies to assist the killer cells. Webinterferon-gamma (IFN-gamma) is measured. If the patient is infected with M. tuberculosis, their white blood cells will release IFN-gamma in response to contact with the TB antigens. The QFT-G results are based on the amount of IFN-gamma that is released in response to the antigens. Clinical evaluation and additional tests (such as a chest
