The sweat test that checks blood sugars

COULD examining sweat soon replace the fingerprick tests people with diabetes use to monitor their blood sugar levels?

A device developed by researchers from the University of California in the US which checks sugar levels in sweat has been shown to be highly accurate.

Sweat, like blood, carries sugar. The new technology, which takes just a minute to work, consists of a flexible plastic strip with a ‘sensor’ surface that’s placed on the fingertip; the sugar in the sweat reacts to the sensor, producing an electrical current that’s converted into a glucose reading.

The device is more than 95 per cent accurate in predicting blood glucose levels, reports the journal ACS Sensors.
