[Are you able to smell a diagnosis ?]

Since centuries, the human clinical observation skills include our capacity to smell. However, it is well known that this particular capacity is largely outraced by our lovely dogs. Some centers around the world are actively training these dogs in order to provide a correct diagnosis for particular diseases. This clinical observation has given rise to intensive development of digital tools which are able to recognize patterns of volatile organic compounds (VOC's) in the exhaled air, but not only. It is not a single VOC which is important but an association - a specific pattern - which at the end represents the signature of a disease. This widely opens the door to applications both in the diagnostic field, as well as for follow-up of treated patients.
