Pulmonary tuberculosis is an important public health problem. Early diagnosis and treatment is necessary for successful patient outcomes. However, diagnosis of pulmonary tuberculosis is difficult in cases with an unusual presentation and often requires a lung biopsy. The tuberculosis polymerase chain reaction results in tissue sample have potential for early diagnosis and treatment initiation for pulmonary tuberculosis. The relatively low sensitivity limit the use of this test in the detection of the pulmonary tuberculosis.
