0 reports arrived in the 12 months to August 2026, and none in the 12 months before.

The event types recorded are malfunction (95.7%), injury (4.3%) and other (0.1%); across all glucose dehydrogenase, glucose reports (product code LFR) death is recorded in 0% and malfunction in 93%. Event type is the reporter's classification of the report, not a verified outcome.

The patient problems coded most often are hypoglycemia, hyperglycemia and therapy/non-surgical treatment, additional. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
