How Does the Non-Pricking Glucose Meter Work?

One FDA-approved type of non-pricking glucose meter is a wristwatch-like device that picks up glucose levels from skin fluid, and another approved device reads interstitial fluids from a catheter planted just under the skin, reports MedicineNet. A device that reads a wire-like sensor beneath the skin also has a mobile app that allows health care providers to track it, states the U.S. Food and Drug Administration. These devices supplement but do not replace standard invasive blood glucose meters.

The prescription-only glucose monitoring wrist device is completely noninvasive and shows patterns in glucose levels rather than isolated results, explains MedicineNet. A diabetic wearer can read its display to watch for oncoming episodes of hypoglycemia or hyperglycemia but must confirm the results using traditional testing methods. The catheter device measures glucose level trends that the user or health care provider must then download for analysis.

The glucose monitoring app automatically passes data on glucose levels to the mobile devices of the patients and health care providers to monitor for dangerous trends, according to the U.S. Food and Drug Administration. Readings from standard blood glucose meters must calibrate the devices and confirm data, and health care providers must base insulin doses on traditional invasive readings.
