390 medical device reports received by FDA name the brand "Medisense Companion 2 Meter" (blood glucose meter); the manufacturer given most often on reports is Medisense; received from September 1996 to December 1999. 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 (99.7%); across all hexokinase, glucose reports (product code CFR) death is recorded in 0.1% and malfunction in 83.6%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are calibration error (21.8%), high readings (1.3%) and other (for use when an appropriate device code cannot be identified) (0.8%). 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."
