Normal values for lymphocyte culture interferon are usually within 24. 1. Mixed lymphocyte culture interferon test is a common and important indicator for checking tuberculosis in the clinic, and is generally used together with Mycobacterium tuberculosis antibody test as a diagnostic criterion for tuberculosis. 2. If the test value is less than 24, you can initially rule out tuberculosis infection, but still need to observe whether there are symptoms such as fever, low fever, etc. If there are no symptoms, you can periodically review this indicator. 3. If the lymphocyte culture interferon value is greater than 24, and the patient is accompanied by symptoms such as low fever in the afternoon, emaciation, loss of appetite, etc., tuberculosis infection should be considered. We should go to the hospital in time, complete the relevant examination, and carry out targeted treatment after a clear diagnosis.
