Is a strong positive TB test a tuberculosis tuberculosis?

The tuberculin test is to determine whether you have been infected with Mycobacterium tuberculosis by intradermal injection of a pure protein derived from tuberculosis bacteria and observing the local skin reaction after 48-72 hours. If redness, induration, etc., are present, it indicates a positive result.

First, it is the case of tuberculosis

1. No: If the patient has not been vaccinated with BCG vaccine or the vaccine is invalid, it may lead to tuberculosis bacillus infection and cause tuberculous pleurisy, and the tuberculin test can be negative;

2. Yes: When a patient has tuberculosis disease, the body's immune system will produce corresponding antibodies under the stimulation of inflammation, and then the tuberculin test will show a positive result.

Second, it is not the case of tuberculosis

In addition to tuberculosis, other causes can also cause this condition, such as AIDS, post-organ transplantation, and malignant tumors, all of which can lead to a positive tuberculin test result due to low autoimmunity. It is recommended to go to the hospital to complete the relevant examinations and actively treat the underlying disease under the guidance of a doctor.

Some people may also be infected with Mycobacterium tuberculosis due to frequent contact with TB patients or long-term exposure to high-risk TB environments, but they do not develop the disease, so false-positive results can also occur. For such people, excessive panic and anxiety should be avoided and a good attitude should be maintained.
