The balance of chemicals present in your exhaled breath can be used to diagnose medical conditions, and reveal details about your body’s unique chemistry. These compounds are some of the body’s waste products – metabolites, and have already been shown to reveal conditions such as lung infections and stomach cancer.
But new research has found that the levels of compounds in breath can act as a “fingerprint”, being unique and stable enough to distinguish individuals from one another. But while it is unlikely to be used in identification, the system promises easy prescription of personalised medicine, tailored to your body.
