Detection of specific cellular immune response function of Mycobacterium tuberculosis

Detection of specific cellular immune response function of Mycobacterium tuberculosis By quantitatively detecting γ -interferon released by whole blood cells stimulated by specific antigen of Mycobacterium tuberculosis in vitro, it can be judged whether it has specific cellular immune response against Mycobacterium tuberculosis, which can be used for auxiliary diagnosis of tuberculosis. Positive is enough, the general specificity and sensitivity are about 80%, which is a very good auxiliary examination method. I have two patients, and through this examination, I avoided thoracotomy.
