The diagnosis of tuberculosis primarily involves combining relevant clinical symptoms, such as whether there is cough, expectoration, low fever, night sweats, and blood in phlegm. It also requires considering the patient's chest imaging features, whether there is obvious infection, fresh exudation, cavities, as well as sputum tests. For example, if the sputum stain for acid-fast bacilli is positive, and the sputum culture is positive, using these comprehensive diagnostic methods, tuberculosis can be diagnosed, after which anti-tuberculosis treatment should be initiated.
