A test that uses teardrops to measure blood glucose levels may signal the end of finger prick tests for diabetes, say researchers.
The prototype, which is being developed at the University of Central Florida in America, could also be used to screen patients for impaired glucose tolerance.
The test requires a single teardrop for analysis.
If blood glucose levels are in the normal range, the solution in the device turns pink.
If levels are too high, the solution turns a dark red.
“It’s so simple, it’s wonderful,” said Professor Florencio Hernandez, who has helped develop the device.
“It means you can address the problem before the disease does a lot of damage.”
