<s>[INST] Is there a test for the detection of TB disease (“active TB”)? [/INST] Identification of individuals with active TB disease is critical to TB control. Those suspected of having TB disease may undergo a number of tests to confirm the diagnosis (e.g. chest x ray, sputum culture, smear microscopy, PCR). Samples from the sputum or other sites are collected and cultured to categorically confirm the diagnosis of TB and to determine susceptibility of the strain to a range of antibiotics used for treatment. The T-SPOT.TB test may be used as a diagnostic aid in suspected TB disease patients when used in conjunction with radiography and other medical and diagnostic evaluations. The T-SPOT.TB test, like a TST and the ELISA based TB blood test, detects TB infection but does not differentiate between active TB disease and latent TB infection. Source: T-SPOT ASIA.
