218 medical device reports received by FDA name the brand "CardioChek Plus analyzer" (clinical chemistry analyzer); the manufacturer given most often on reports is Pts Diagnostics; received from March 2019 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

7 reports arrived in the 12 months to August 2026, down 53% from 15 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 (99.5%) and injury (0.5%); across all glucose oxidase, glucose reports (product code CGA) death is recorded in 0.2% and malfunction in 91%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are electrical /electronic property problem (93.6%), incorrect, inadequate or imprecise result or readings (1.4%) and overheating of device (1.4%). The patient problems coded most often are burning sensation and chemical exposure. 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."
