There is no data on the accuracy of tspot and xpert. First of all, the advantage of gene- xpert is that it can detect tuberculosis, and if it can avoid its disadvantages, it can prove that it is active tuberculosis and carry out anti-tuberculosis treatment. However, tspot detects current infection, that is, the body is infected with mycobacterium tuberculosis, and it has a very high detection rate for latent tuberculosis patients, and it can detect the infection when the body’s immune status is relatively good, and the disease has not yet broken out. It can detect the infection when the body’s immune status is relatively good and the disease has not yet broken out, and then formulate a treatment plan according to the degree of risk of developing active tuberculosis. Gene-xpert claims that its sensitivity is more than 90%, which is actually based on the fact that the patient is bacillus-positive TB patient, and the sensitivity is about 68% if the patient is bacillus-negative TB patient. Moreover, it is worth mentioning that the CFDA (State Food and Drug Administration) approval states that gene-xpert is used for bacillus-positive patients, which means that it is very difficult to get bacillus-carrying specimens when gene-xpert is used for sampling, and most of the tuberculosis patients are bacillus-negative tuberculosis, and it is even more difficult to take samples of extrapulmonary tuberculosis, which makes it easy to get a false-negative for gene-xpert; by comparison, tspot uses peripheral blood. In contrast, tspot uses peripheral blood, which does not require bacterial specimens and has a great advantage in the diagnosis of extrapulmonary tuberculosis.
