FDA clears Libre Duo 10 Day, first device tracking ketones and glucose together

The FDA has authorized the Libre Duo 10 Day Continuous Dual Glucose Ketone Monitoring System for diabetes patients aged 2 and up. It is the first wearable in the U.S. to continuously track ketone levels and the first worldwide to combine continuous ketone and glucose monitoring in one device. Sensors measure both substances every minute in fluid beneath the skin and send readings wirelessly to a paired smartphone.
