Summary
This study tests a new way to screen for type 2 diabetes by measuring sugar levels in fingernails. Researchers will compare results from 100 adults (half with known diabetes, half without) to standard blood tests. The goal is to see if this simple, non-invasive method can accurately identify people who may have diabetes.
