Identify the disease by one blow
Doctors may soon decide a person’s risk of 17 different and separate diseases -including Parkinson’s and various cancers – just by proceed a quick read of their breath, thanks to a new low-cost and non-invasive device developed by researchers in Israel.
Diagnostic skills based on breath samples have been demonstrated in the previous days, but until now, there has not been systematic proof of the hypothesis that different and unrelated diseases are distinguished by distinct chemical breath signatures.
Technologies expanded to date for this type of recognition have been limited to detecting a small number of clinical disorders, without differentiation between unconnected diseases.
The study of more than 1,400 patients included 17 different and unconnected diseases: kidney cancer, lung cancer, colorectal cancer,stomach cancer, head and neck cancer, ovarian cancer, bladder cancer, prostate cancer, Crohn’s disease, irritable bowel syndrome, ulcerative colitis,Parkinson’s disease (two types),preeclampsia, multiple sclerosis, pulmonary hypertension, and chronic kidney disease.
Samples were collected between January 2011 and June 2014 from 14 departments from nine medical centers in five countries: Israel, France, the US, Latvia and China.With a advanced technology called “artificially intelligent nanoarray,” developed by Haick, the researchers were able to corroborate the clinical capability of the diagnostic technology.
The array enables fast and cheap diagnosis and classification of illness, based on “smelling” the patient’s breath and using artificial intelligence to analyse the data obtained from the sensors.
The system has noticed and classified various diseases with an average accuracy of 86 per cent,” researchers said.
