First seen Jan 11, 2026 · Last updated Jun 19, 2026 · Updated 25 times
Summary
This study is testing a new device that uses Raman spectroscopy—a type of light technology—to measure blood sugar without needing a finger prick. Researchers will compare its readings to traditional blood tests in 49 people with diabetes or healthy volunteers. The goal is to see if this painless method is accurate and acceptable to patients.
