318 medical device reports received by FDA name the brand "Precision Xtra Monitor" (blood glucose meter); the manufacturer given most often on reports is Medisense; received from January 2001 to October 2004. 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 (84.9%), other (9.7%) and injury (3.8%); 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 incorrect or inadequate test results (47.2%), high test results (16.4%) and high readings (13.5%). The patient problems coded most often are blood glucose, low, therapy/non-surgical treatment, additional and hospitalization required. 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."

Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
