Mycobacterium tuberculosis gamma-interferon test results are negative and positive. Gamma-Interferon test is mainly used to determine the presence of Mycobacterium Tuberculosis infection, because the specific antigen of Mycobacterium Tuberculosis will produce gamma-interferon when it stimulates the T-cells in the body, so it can be detected by gamma-interferon. gamma-Interferon test has two kinds of results, i.e. negative and positive. If the γ-interferon test result is negative, it means that the body is very unlikely to be infected with tuberculosis bacilli; if it is positive, it suggests that the body may have been infected with tuberculosis bacilli, but this test can not determine whether it is a previous infection or a current infection, or whether it is active tuberculosis or not, and it is necessary to combine with the results of the CT of the chest and the sputum culture and other tests for comprehensive consideration. If the gamma-interferon test result is positive, you should go to the hospital in time, and under the guidance of the doctor to carry out the relevant examination and treatment.
