An electronic-nose (e-nose) had been investigated as a diagnostic tool for tuberculosis by examining exhaled breath of the patients. Universitas Gadjah Mada has developed an e-nose device for TB diagnostic tool. Here the investigators test the device in order to analyze the sensitivity and specificity electronic-nose as a screening tool for tuberculosis.


The study population consists of 2 groups:

Group 1 - presumptive TB patients. Group 2 - residents of area with high risk of TB.

Study participants provide written informed consent. The participants are asked to breathe normally using a mask for 2 times then inhale and exhale in a forced expiratory volume to the air collecting bag until the collecting bag is full (two times). The collecting bag is sealed and connected to the e-nose machine via a collecting hose and HEPA-filter protecting the e-nose from microbes. The breath pattern will be recorded in the e-nose device, which is connected to a laptop that will display the recorded breath pattern. Other data are collected: clinical symptoms, results of chest X-ray, smear microscopic, and Xpert MTB/Rif examinations.
