Spit science: why saliva is great way to detect disease

Scientists have unlocked saliva's diagnostic potential, detecting diseases like cancer, diabetes, and even Alzheimer's through simple spit tests. This non-invasive method, unlike blood tests, offers painless and inexpensive screening. Raman spectroscopy, a light-based technique, identifies subtle molecular changes in saliva, enabling early detection.
