Tuberculosis screening can begin with an initial tuberculosis test. If the tuberculosis test is negative, it means that there has been no infection with Mycobacterium bovis. If the TB test is positive, it indicates an infection with Mycobacterium tuberculosis. If the tuberculosis test is strongly positive, it suggests that there may be active tuberculosis. At this time, sputum examination is then performed, and if the sputum culture is positive for Mycobacterium tuberculosis, or when the sputum smear is positive for Mycobacterium antacidum, and if there are patchy shadows, cavernous tuberculosis, disseminated lesions in the chest on imaging, and if there are typical clinical symptoms, such as coughing, coughing with blood, coughing up blood, fever, night sweats, weakness, and wasting, the diagnosis of active tuberculosis can be considered and anti-tuberculosis treatment is needed.
