It is very common to come across false positive TST results due to BCG vaccines applied routinely in countries. Aim: To evaluate the patients who was referred to us who had positive TST without any TB contact. Method: 171 patients were prospectively followed up between September 2011 and February 2013. Result: 51% of the patients were male, the median age was 84 months and the median duration of the symptoms was 5 months. The indications of TST were cough (77%), sputum (36%), wheezing (30%), dyspnoea (18%), cervical lympho-adenopathy (7%). 43% of chest X-rays were normal and increase of bronchovasculary signs (22%), bronchopnomonic infiltrations (18%), suspicious lympho-adenopathy view (17%) were other findings. 49% of the patients had CT and the results were normal in 56%. Right middle lob atelectasis (n=15), infiltration (n=13) and big lymp nodes (n=12) were detected. Interferon gama release assay was performed in 81% of the patients and 96% of them were normal. 15% required to microbiological tests and all were negative The patients follow up period was 12,4 ±3,7 months. The most common diagnosis established with the patients were asthma (% 47), alergic rhinitis (17%), and reactive lympho-adenitis (7%). Conclusion: Active TB was not found in any positive TST without any TB contact and the most common diagnosis was asthma and allergic rhinitis. It was shown in our study that the false positive of TST was high. ER -
