Spit Science: Warum Speichel eine großartige Möglichkeit ist, Krankheiten zu erkennen

* Scientists have developed ways to analyse spit for the tiniest traces of illness – from mouth cancer to diabetes, and even brain diseases like diabetes, Alzheimer’s, Parkinson’s, heart disease, gum disease, infections, and various cancers.

* What’s new is the speed and precision. Today’s techniques can detect subtle molecular shifts that would have been impossible to measure just a few years ago.

* What makes saliva so appealing is its simplicity – no needles, no specialist clinics. Samples can often be collected at home, posted to a lab and analysed within hours. This could make a huge difference in places with limited access to healthcare or for people who avoid doctors out of fear, cost or time.
