What does weak positive tuberculosis antibody mean?

The antibody to Mycobacterium tuberculosis is weakly positive. This does not necessarily mean that the patient has pulmonary tuberculosis. It is just a test within the serum range. Because it is weakly positive, the patient may be infected with Mycobacterium tuberculosis, but the symptoms of tuberculosis cannot be confirmed. At this time, other formal examinations can be further performed to achieve the purpose of diagnosis. In daily life, we must strengthen the prevention of tuberculosis, especially for young children, who must be aware of some precautions.

What does weak positive tuberculosis antibody mean?

A positive tuberculosis antibody test does not mean that you have tuberculosis. It is a serological test. As long as you have been infected with Mycobacterium tuberculosis, the test will be positive. It is only a reference for diagnosing tuberculosis. Most Chinese people have been infected with Mycobacterium tuberculosis, but infection with Mycobacterium tuberculosis does not mean tuberculosis. The vast majority of people will not develop the disease.

The PPD test (tuberculin) is also a reference for diagnosing tuberculosis. It involves intradermal injection of 0.1% of the drug solution, and the results are observed in 48-72 hours. For the PPD test, only a strongly positive result is meaningful. If the reaction is negative, it means that there is no infection with tuberculosis bacteria. A weak positive or positive reaction only means that there is infection with tuberculosis bacteria, but it cannot be diagnosed as tuberculosis.

How to prevent tuberculosis in children
