Additional Manufacturer Narrative

E.1 INITIAL REPORTER FACILITY NAME: (B)(6). INVESTIGATION SUMMARY THIS STATEMENT SUMMARIZES THE INVESTIGATION RESULTS REGARDING A COMPLAINT THAT ALLEGES FALSE POSITIVE WHEN USING KIT FLU VERITOR SYSTEM 30 TEST JAPAN (MATERIAL#: 256052), BATCH NUMBER UNKNOWN. THE CUSTOMER REPORTED THAT THERE WAS A THIN LINE-LIKE CRACK THAT WAS OBSERVED ON THE A LINE OF THE TEST CARTRIDGE, WHICH WAS READ AS POSITIVE. THE SAME EXTRACT WAS INOCULATED ONTO ANOTHER CARTRIDGE THAT THEN GAVE A NEGATIVE RESULT. BD QUALITY PERFORMS A SYSTEMATIC APPROACH TO INVESTIGATE ALL COMPLAINTS. THIS APPROACH INVOLVES REVIEW OF MANUFACTURING BATCH HISTORY RECORDS, VISUAL INSPECTION OF RETENTION SAMPLES, AND VISUAL INSPECTION OF CUSTOMER RETURNED SAMPLES, IF APPLICABLE. BATCH HISTORY RECORD (BHR) REVIEW AND RETAIN SAMPLE TESTING WERE NOT PERFORMED AS THERE WAS NO BATCH NUMBER PROVIDED. NO SAMPLES WERE RECEIVED; THEREFORE, RETURN SAMPLE ANALYSIS COULD NOT BE PERFORMED. FROM THE 4 PHOTOS PROVIDED, 1 PHOTO SHOWS 4 DEVICES WITH AN EXTREMELY FAINT LINE AROUND COLUMN A. IT IS DIFFICULT TO DISTINGUISH WHETHER IT IS A LINE OR A SCRATCH. SINCE NO PHOTOS OF THE VERITOR ANALYZER RESULTS WERE RETURNED, WE ARE UNABLE TO CONFIRM THE COMPLAINT THROUGH THE PROVIDED PHOTOS. A TREND ANALYSIS FOR FALSE POSITIVE WAS CONDUCTED, NO ADVERSE TREND WAS IDENTIFIED. THERE WERE NO CORRECTIVE ACTIONS TAKEN AT THIS TIME. THIS MDR IS BEING SUBMITTED AS PART OF A RETROSPECTIVE REVIEW OF RECORDS DATING APRIL 2023¿2025, UNDER CAPA 11910483.
