Abstract: Smearnegative tuberculosis has been a difficulty in the diagnostic process of pulmonary tuberculosis (TB). Diagnosis of TB mainly relies on the clinical features, chest imaging manifestations and laboratory tests. Although sputum culture is the gold standard in diagnosis of TB, it has a very poor sensitivity and takes a relatively long period of time to get. Considering the limitations of conventional methods to test TB, new molecular methods and cellular immunological examinations are getting more and more attention in TB clinical diagnosis.
