The indicators that are generally looked at for tuberculosis are the tuberculin test, chest x-ray, and mycobacterium tuberculosis test. There are several types of tuberculosis, the most common of which is tuberculosis. 1. Tuberculin test: used as an epidemiologic indicator of tuberculosis infection, but generally of little significance in the diagnosis of adult tuberculosis. A positive result simply indicates that the patient has been infected with Mycobacterium tuberculosis, but does not necessarily mean that he or she has tuberculosis. Its diagnostic value is greater for infants and young children, and a strong positive reaction in a person under 3 years of age should be regarded as active tuberculosis with recent infection. 2. X-ray examination: Generally speaking, chest X-ray is the first choice for diagnosing tuberculosis and can be used to diagnose different types of tuberculosis. 3. Mycobacterium tuberculosis examination: this index is the most specific method to confirm the diagnosis of tuberculosis, mainly by direct smear microscopy is most commonly used, if the bacillus is positive, then the diagnosis of tuberculosis can basically be established. If you suspect tuberculosis, you should go to the designated hospital in time to complete the relevant examinations and ask the doctor to diagnose the disease according to the examination results. If the disease is diagnosed as tuberculosis, it should be treated in time to avoid delaying the condition.
