Smell is a primary human sense, key to our survival.
Like a super-sensitive human nose, an experimental technology can “smell” and identify the chemical composition of a person’s breath and then diagnose up to 17 potential diseases, according to the scientists who developed it.
These researchers, led by Hossam Haick of the Technion – Israel Institute of Technology, say their Na-Nose, which uses nanorays to analyze breath, can identify Parkinson’s disease, various cancers, kidney failure, multiple sclerosis and Crohn’s disease with 86% accuracy.
“I would say our technology in many cases (is) equivalent to the accuracy of the currently available invasive technology,” Haick said, adding that for some diseases, including gastric cancer, Na-Nose has a “much higher” accuracy rate than currently available technologies. And, unlike most screenings, including standard blood tests, breath analysis technology is noninvasive – a benefit most patients would appreciate.
