An international team of researchers confirmed that some diseases are characterized by different “chemical signatures” identifiable in breath samples.
17 diseases, 13 shared chemical components
The study of more than 1,400 patients included 17 different and unrelated diseases: lung cancer, colorectal cancer, head and neck cancer, ovarian cancer, bladder cancer, prostate cancer, kidney cancer, stomach cancer, Crohn’s disease, ulcerative colitis, irritable bowel syndrome, Parkinson’s disease (two types), multiple sclerosis, pulmonary hypertension, preeclampsia and chronic kidney disease.
The researchers tested the chemical composition of the breath samples and discovered that all 17 of the diseases contained the same 13 chemical components, albeit in different compositions.
“Each of these diseases is characterized by a unique fingerprint, meaning a different composition of these 13 chemical components,” Prof. Haick explained in a statement. “Just as each of us has a unique fingerprint that distinguishes us from others, each disease has a chemical signature that distinguishes it from other diseases and from a normal state of health.”
