Introduction: The definitive diagnosis features can be demonstrated or mycobacteria can be isolated from the body fluids or from sputum or from gastric lavage. Various other methods, such as polymerase chain reaction are also available. It is wel and culture is difficult and time consuming and other tests are complex and technically more demanding. In this study, we correlated the results of QuantiFERON test and sputum positivity. Material and methods: Total 150 subjects were included in this study. The clinical features and detailed history of each case wa physical examination. Patients were tested for Results: The results obtained in this study showed patients may not be able to detect all methods for the diagnosis of tuberculosis patients is more tuberculosis patients. The combination of tuberculin skin test had yield 96.6% cases as positive in our study which is far better than using a single test. Conclusion: Use of QuantiFERON conventional methods of diagno tuberculin skin test yields the maximum number of true positive cases of tuberculosis. The levels of new markers, serum interferon gamma ( combining it with tuberculin skin t even in latent cases.
