The present invention provides a process and method for the early detection and diagnosis of disease by reading and decoding volatile organic compounds (VOCs) for signatures associated with a specific disease. From its outset, each disease begins producing its own unique set of volatile organic compounds. For many diseases, this early-stage detection may be many months or years before noticeable symptoms. The VOC emissions when analyzed, result in a “signature” that identifies and distinguishes the developing, or at later stages, the developed disease. The device assays non-invasively obtained biosamples in real-time to output a VOC based signature that, when correlated with data in a disease signature library, identifies one or more diseases associated with the sample.
