How can TB be diagnosed?

The usual tests employed by doctors to diagnose TB include chest x-ray examination and sputum examination. Sputum examination is done by direct smear under microscopy as well as culture for the germs. Further investigations may be required, e.g., computerized tomography, bronchoscopy, lung biopsy, etc.
