T-SPOT test has a high accuracy and high sensitivity and specificity in the diagnosis of tuberculosis.
T-SPOT test is a new type of laboratory test developed in recent years for the diagnosis of tuberculosis, which is an in vitro gamma-interferon response assay based on the immune response of T cells.
Studies have shown that the sensitivity of the T-SPOT test in the diagnosis of tuberculosis is 89.9% (meaning that in the tuberculosis population, the chance of detecting a positive test is 89.9%.) and the specificity is 67.4%. , with a specificity of 67.4% (the chance of detecting a negative test in a population without TB disease is 67.4%). Therefore, the T-SPOT test is a more accurate method of detecting TB.
However, the most accurate tests are sputum tests for Mycobacterium tuberculosis and sputum cultures for Mycobacterium tuberculosis.
