Tuberculosis testing without X-ray is a new device

Bangladeshi and Dutch scientists have developed tuberculosis diagnostic devices and named eNose (electronic nose). The mechanism of action of eNose is described by the researchers in the journal Nature Materials.

In order to diagnose tuberculosis, doctors have to prescribe the sputum of the patient for microscopy under laboratory conditions. The culture takes a long time, maybe several weeks, sometimes several months. Patients also need a chest x-ray to conclude that the disease. ENose can overcome these nuisances.

With the new diagnosis, the patient is asked to breathe in an airbag, which then passes through the metal oxide sensors inside the device. These sensors will detect volatile organic compounds caused by Mycobacterium tuberculosis, a bacterium that causes tuberculosis. Then, the data from the sensors is analyzed with the help of the computer and is compared to the normal parameters. The device is capable of rapidly identifying several strains other than M. tuberculosis.

After being piloted in the Bangladesh National TB Program, eNose has shown its simplicity, speed, and high sensitivity. According to Zeaur Rahim, lead researcher, this is a revolutionary invention that provides convenience to users in areas with high TB prevalence. In addition, this new device reduces the risk of infection because there is no need to directly process the specimen.

In addition, eNose also has the advantage of being accurate and capable of early diagnosis. It is essential for TB control in countries with active TB.

ENose is marketed under the trade name DiagNose. It will reduce the cost of each TB check to less than $ 10, which is a very low amount compared to traditional diagnostic methods.
