    Additional Manufacturer Narrative · 0

    INVESTIGATION SUMMARY: THE COMPLAINT INVESTIGATION FOR DISCREPANT RESULTS WHEN USING BD COR¿ CTGCTV2 (REF. (B)(4)) FROM LOT 4234115 WAS PERFORMED BY THE REVIEW OF MANUFACTURING RECORDS, REVIEW OF CUSTOMER¿S DATA AND BY THE COMPLAINT¿S HISTORY REVIEW. CUSTOMER REPORTED A SUSPECTED FALSE TV POSITIVE SAMPLE LINKED TO AN UNUSUAL CURVE WITH BD COR¿ CTGCTV2 (REF# (B)(4)) KIT LOT 4234115. REVIEW OF THE MANUFACTURING RECORDS OF INDIVIDUAL KIT LOTS COMPONENTS INDICATES THAT THOSE LOTS WERE MANUFACTURED ACCORDING TO SPECIFICATIONS AND MET PERFORMANCE REQUIREMENTS. CUSTOMER PROVIDE THE RUN (B)(6) THAT INCLUDES THE SPECIFIC SAMPLE MENTIONED IN THE COMPLAIN TEXT AND IT WAS INVESTIGATED. THE RUN WAS ANALYZED AND MANUAL PCR CURVE ADJUDICATION OF THE POSITIVE SAMPLE REVEALED STEP DISLOCATIONS IN THE CY5 CHANNEL (TV TARGET) IN BOTH THE RAW AND BACKGROUND SIGNALS. THIS ATYPICAL CURVE DOES NOT SUGGEST TRUE AMPLIFICATION. FURTHERMORE, SIMILAR STEP DISLOCATIONS WERE OBSERVED ACROSS THE FOUR OTHER CHANNELS GIVING POSITIVE RESULT FOR THE INTERNAL CONTROL (ROX CHANNEL) AND ONE OF THE GC TARGETS (CY5.5 CHANNEL). THIS MAKES IT UNLIKELY THAT THE TV TARGET POSITIVE RESULT IS A TRUE AMPLIFICATION. NEVERTHELESS, MANUAL CURVE ADJUDICATION HAS LIMITATIONS; VISUAL EXAMINATION OF PCR CURVES FOR LOW SIGNAL IS A CONSERVATIVE ASSESSMENT OF THE DATA. THERE IS NO INDICATION OF A REAGENT ISSUE BASED ON THE ANALYSIS OF THE COMPLAINTS RECEIVED FOR DISCREPANT RESULTS ON THE BD COR¿ CTGCTV2 LOT USED BY THE CUSTOMER. THE ROOT CAUSE WAS NOT IDENTIFIED. BD CANNOT CONFIRM THE COMPLAINT BASED ON THE INVESTIGATION THAT WAS PERFORMED. BD DID NOT INITIATE A CORRECTIVE AND PREVENTIVE ACTION SINCE NO NEW HAZARD WAS IDENTIFIED. BD APOLOGIZES FOR THE INCONVENIENCE THAT THIS MAY HAVE CAUSED. BD QUALITY WILL CONTINUE TO MONITOR FOR TRENDS.
