FDA's MAUDE database holds 319 reports that name the brand "Contour Next EZ" (blood glucose meter), received between February 2013 and August 2026; the manufacturer given most often on reports is Ascensia Diabetes Care US. Spellings of one product vary from report to report.

6 reports arrived in the 12 months to August 2026, down 62% from 16 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 (92.8%) and injury (7.2%); across all system, test, blood glucose, over the counter reports (product code NBW) death is recorded in 0% and malfunction in 90.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are missing test results (57.4%), incorrect, inadequate or imprecise result or readings (10.3%) and high readings (6.3%). The patient problems coded most often are hyperglycemia, hypoglycemia and dizziness. 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."
