The system involves the user sticking each end of the test strip to the back of the phone to turn off the camera flash. After a finger puncture, a drop of blood falls onto the biosensor at the end of the test strip. Using photodiodes powered by the phone’s flash, blood test data is transmitted to the device, where machine learning in the app processes the information and calculates blood glucose readings.
The system provides approximately the same accuracy as existing home glucose meters. Researchers believe the technology could be an affordable solution for patients who can’t afford to do self-tests because glucometers and test strips aren’t always readily available.
