372 medical device reports received by FDA name the brand "Atellica IM High-Sensitivity Troponin I (TnIH)" (immunoassay method troponin subunit); the manufacturer given most often on reports is Siemens Healthcare Diagnostics; received from August 2019 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

46 reports arrived in the 12 months to August 2026, up 12% from 41 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 (100%); across all immunoassay method, troponin subunit reports (product code MMI) death is recorded in 0.1% and malfunction in 87.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are high test results (91.9%), low test results (1.9%) and false positive result (0.5%). The patient problems coded most often are chest pain. 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."
