Nanoarray sniffs out and distinguishes ‘breathprints’ of multiple diseases

EXCERPT: An international team of 63 scientists in 14 clinical departments have identified a unique “breathprint” for 17 diseases with 86% accuracy and have designed a noninvasive, inexpensive, and miniaturized portable device that screens breath samples to classify and diagnose several types of diseases, they report in an open-access paper in the journal ACS Nano.

As far back as around 400 B.C., doctors diagnosed some diseases by smelling a patient’s exhaled breath, which contains nitrogen, carbon dioxide, oxygen, and a small amount of more than 100 other volatile chemical components. Relative amounts of these substances vary depending on the state of a person’s health. For example, diabetes creates a sweet breath smell. More recently, several teams of scientists have developed experimental breath analyzers, but most of these instruments focus on one disease, such as diabetes and melanoma, or a few diseases....

Believe it or not there is a doctor in my family. A brother of mine is involved with something similar but I'm not allowed to say what. He was telling me that they have to be careful putting these devices in the hands of John Q Public. They cannot be advertised as actual diagnostic devices unless they go through a barrage of licences, applications, testing etc which could take years. They don't want to wait, so the device is coming and for the most part they're hoping the owners learn to help themselves by using the data gathered. At no point will it actually tell you that you have this, that or the other thing. 

He also made predictions based on sample sizes from the data gathered in a test. Nothing was said for awhile until he received a peer review indicating his analyses were 95% accurate. The wheels are now in motion, see what happens. You'd love to see his workshop, I've never sen so many tiny electronic parts in my life. He's also built prototypes of various miniature devices used by heart surgeons and cardiologists.

Love your 'Starship Trooper-esque' recruitment avatar theme. Looks like you got the bugs out.
