title: [USE OF QuantiFERON-TB Gold in Tube AND T-SPOT.TB FOR DIAGNOSING PATIENTS WITH SUSPECTED PULMONARY TUBERCULOSIS].
abstract: OBJECTIVE
  We analyzed the use of QFT-TB Gold in Tube and T-SPOT.TB in diagnosing patients with suspected pulmonary tuberculosis.
  
  
  METHODS
  We evaluated 122 patients with suspected pulmonary tuberculosis (where chest X-ray showed consolidation or. tumor shadow in predilection sites of pulmonary tuberculosis and through contact investigation). QFT-TB Gold and T-SPOT.TB were performed for all the patients. The positive response rate and history of pulmonary tuberculosis in patients who showed positive results for the tests were evaluated.
  
  
  RESULTS
  Ninteen patients showed positive results for QFT-TB Gold, and 9, for T-SPOT.TB. Four patients showed positive results for QFT-TB Gold, and 3, for T-SPOT.TB in 4 patients with active tuberculosis. The patients without active tuberculosis whose IGRAs were positive (old pulmonary tuberculosis, Mycobacterium avium cmplex, pneumonia, lung cancer, pulmonary sequestration, bronchiectasis) had a past history of pulmonary tuberculosis.
  
  
  CONCLUSIONS
  The positive result rate of QFT?-TB Gold was higher than that of T-SPOT.TB in the subjects with suspected pulmonary tuberculosis. We think that QFT-TB Gold reflected the past history of pulmonary tuberculosis.
