1, once the patient has the above-mentioned suspicious TB symptoms should go to the hospital as soon as possible. 2.Sputum tuberculosis examination is the main method to confirm the diagnosis of tuberculosis: because the mucous membrane of trachea and bronchus of normal people has glands, which can secrete mucus to adsorb dust and pathogenic bacteria and expel it by coughing. When tuberculosis lesions cause inflammation in the lungs, more exudate and necrotic tissue are mixed with bronchial secretions to form bacterium-containing sputum, which is coughed out with sputum when coughing, and these bacteria can only be found by checking sputum. Sputum examination is not only the most reliable means to confirm the diagnosis of tuberculosis, but also to determine whether the disease is infectious and to understand the effectiveness of treatment after medication.
