    THERE ARE TWO POTENTIAL LOT NUMBERS FOR THIS DEVICE: D4. MEDICAL DEVICE LOT#: 3137729. D4. MEDICAL DEVICE EXPIRATION DATE: 30-NOV-2024. D4. UNIQUE IDENTIFIER (UDI)#: (B)(4). H4. DEVICE MANUFACTURE DATE: 17-MAY-2023. D4. MEDICAL DEVICE LOT#: 3081371. D4. MEDICAL DEVICE EXPIRATION DATE: 12-OCT-2024. D4. UNIQUE IDENTIFIER (UDI)#: (B)(4). H4. DEVICE MANUFACTURE DATE: 22-MAR-2022. INVESTIGATION SUMMARY: THE COMPLAINT INVESTIGATION FOR DISCREPANT RESULTS WHEN USING THE BD MAX¿ ENTERIC BACTERIAL PANEL ASSAY (REF. 442963) FROM LOTS: 3137729 AND 3081371 WAS PERFORMED BY THE REVIEW OF THE MANUFACTURING RECORDS, REVIEW OF CUSTOMER¿S DATA AND BY THE COMPLAINT¿S HISTORY REVIEW. REVIEW OF THE MANUFACTURING RECORDS OF BD MAX¿ ENTERIC BACTERIAL PANEL ASSAY INDICATED THAT LOTS: 3137729 AND 3081371 WERE MANUFACTURED ACCORDING TO SPECIFICATIONS AND MET PERFORMANCE REQUIREMENTS. CUSTOMER COMPLAINED ABOUT SUSPECTED STX FALSE POSITIVE RESULTS WHEN USING BD MAX¿ ENTERIC BACTERIAL PANEL KIT FROM LOTS: 3081371 AND 3137729. CUSTOMER PROVIDED DATABASE FROM INSTRUMENT CT1164 FOR INVESTIGATION. SAMPLES (B)(6) IN RUNS #3048 AND SAMPLES (B)(6) IN RUN #3096 MENTIONED BY THE CUSTOMER IN THE COMPLAINT TEXT AS SUSPECTED STX FALSE POSITIVE. BOTH RUNS# 3048 AND #3096 WERE EXTRACTED AND MANUAL PCR CURVE ADJUDICATION OF THE SUSPECTED STX FALSE POSITIVE RESULTS WAS DONE. THE PCR CURVES ANALYSIS REVEALED THAT ALL THE STX POSITIVE RESULTS WERE LINKED TO ATYPICAL CURVES, AND UNLIKELY TRUE POSITIVES, EXCEPT FOR THE SAMPLE TESTED IN POSITION B8 (RUN 3048), WHICH APPEARS TO BE A TRUE STRONG STX POSITIVE SAMPLE. DATABASE ANALYSIS SHOWED THAT INSTRUMENT PUMP #1 PRESENTED A HIGHER UNRESOLVED RATE THAN THE OTHER PUMPS. THIS INFORMATION WAS TRANSFERRED TO BD SERVICE AND A COMPLAINT ON THIS INSTRUMENT IS ALREADY OPENED FOR FURTHER INVESTIGATION. DATA ANALYSIS DID NOT SUGGEST SPECIFIC LOTS LINKED TO POSITIVE RESULTS ISSUES. OVERALL, BASED ON THE INVESTIGATION AND DATA PROVIDED, BD WAS UNABLE TO CONFIRM THE EXACT CAUSE OF THE CUSTOMER¿S POSITIVE RESULTS ALTHOUGH AN INSTRUMENT RELATED ISSUE IS SUSPECTED OF BEING INVOLVED. THE ROOT CAUSE WAS NOT IDENTIFIED. THERE IS NO INDICATION OF A REAGENT ISSUE BASED ON THE ANALYSIS OF THE COMPLAINTS RECEIVED FOR DISCREPANT RESULTS ON THE BD MAX¿ ENTERIC BACTERIAL PANEL ASSAY LOTS: 3081371 AND 3137729. BD CANNOT CONFIRM THE COMPLAINT BASED ON THE INVESTIGATION THAT WAS PERFORMED. BD DID NOT INITIATE A CORRECTIVE AND PREVENTIVE ACTION (CAPA) SINCE NO NEW HAZARD WAS IDENTIFIED. BD QUALITY WILL CONTINUE TO MONITOR FOR TRENDS. THIS MDR IS BEING SUBMITTED AS PART OF A RETROSPECTIVE REVIEW OF RECORDS DATING APRIL 2023¿2025, UNDER CAPA: 11910483.
