Diagnosis of TB

Diagnosis of TB may be difficult due to the difficulty in culturing the slow growing organisms in Laboratory. So other methods besides culturing have to be employed. Medical history, chest X-ray & physical examinations are required for correct diagnosis. Currently two tests 1) The TB skin test & 2) QuantiFERON - TB Gold (QFT-G) test are employed to identify both Active & Latent form of the disease.
