Excluding pulmonary tuberculosis at present, the common clinical methods include chest radiography, sputum examination of antacid bacilli, tuberculin test and so on. 1. Chest X-ray: Chest X-ray can be perfected, if the chest X-ray shows that it is normal, basically, tuberculosis can be excluded. 2. Sputum antacid bacillus test: If the chest X-ray is normal, but there are still symptoms such as low fever, emaciation, night sweating (abnormal sweating after going to sleep, but the sweating stops after waking up), and fatigue etc., then we can improve the sputum antacid bacillus test further, and if everything is normal in the test, then we can rule out pulmonary tuberculosis. 3. Tuberculin test: pure protein derivatives can be injected subcutaneously, and the injection site can be carefully observed to see if there are any hard nodules and redness, if there are no hard nodules and redness, and if there is no immunodeficiency in the examination, tuberculosis can be basically ruled out. After examination, if tuberculosis foci are found and bacilli are detected in sputum, active tuberculosis can be determined clinically. It is necessary to go to the regular hospital to receive anti-tuberculosis treatment in time, do not delay treatment.
