442 medical device reports received by FDA name the brand "Vitros Chemistry Products Phbr Slides" (in-vitro diagnostic); the manufacturer given most often on reports is Ortho-Clinical Diagnostics; received from January 2008 to June 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

6 reports arrived in the 12 months to August 2026, with 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 (100%); across all enzyme immunoassay, phenobarbital reports (product code DLZ) death is recorded in 0% and malfunction in 100%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are incorrect or inadequate test results (65.8%), low test results (16.3%) and high test results (10.2%). 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."
