Dublin, May 10: In a breakthrough that could transform modern diagnostics, scientists have developed advanced techniques to detect a wide range of diseases using just a few drops of saliva — offering a painless and cost-effective alternative to traditional tests.
Researchers say saliva can now be used to identify early signs of conditions such as mouth cancer, diabetes, and even complex brain disorders like Alzheimer’s. This innovation eliminates the need for more invasive methods like blood draws, biopsies, or scans.
Saliva-based testing gained traction during the COVID-19 pandemic as countries adopted it for rapid and non-invasive screening. Now, its potential is expanding well beyond infectious diseases, offering a promising tool for early detection and monitoring of chronic and neurological conditions.
