754 medical device reports received by FDA name the brand "Freestyle Navigator" (continuous glucose monitoring system); the manufacturer given most often on reports is Abbott Diabetes Care USA; received from October 2008 to November 2014. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (90.1%) and injury (9.9%); 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 device problems coded most often are crack (69.5%), moisture damage (12.6%) and fracture (8.9%). The patient problems coded most often are loss of consciousness, hypoglycemia and seizures. 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."
