TB T-cells are positive but there are no symptoms in the body, which usually need to be considered as a carrier or the TB cells themselves are not active. A positive T-cell count indicates the presence of TB virus infection in the body. However, if there are no obvious signs, it means that the TB virus is not in an active stage after infection, and thus does not cause the body to experience the corresponding discomfort. This group of people who are infected with the TB virus but do not show any obvious clinical signs are called carriers, and anti-tuberculosis treatment is still recommended. During the course of anti-tuberculosis treatment, regular tuberculosis T-cell tests reveal varying changes and increases in the number of T-cells, which can indicate whether or not the tuberculosis treatment regimen is effective at that stage, thus helping to treat the tuberculosis infection. In the carrier phase, when the virus is infected but not causing clinical symptoms, the infected patient is still contagious and therefore requires personal protective therapy. In the case of TB T-cells are positive but no obvious symptoms should be timely to the hospital for anti-tuberculosis treatment, under the guidance of the doctor to choose the appropriate drugs to take.
