    Additional Manufacturer Narrative · 1

    SIEMENS HEALTHCARE DIAGNOSTICS HAS CONFIRMED COMPLAINTS REGARDING VARIABILITY OF RECOVERY OF QC AND PATIENT RESULTS WITH THE CSA K4089 FLEX REAGENT CARTRIDGE LOTS 12300BB, 12318BB, AND 13011BB. INTERNAL TESTING HAS CONFIRMED ATYPICAL PERFORMANCE AND INCREASES OF >25% OVER SEVERAL DAYS FOR SAMPLES WITH CSA CONCENTRATIONS BELOW 125 NG/ML. DAILY QC CAN DETECT PERFORMANCE VARIATIONS IN THE ASSAY. ERRORS ARE MOST PRONOUNCED BELOW 125 NG/ML WHERE MAINTENANCE THERAPY OCCURS, THEREFORE, DOSAGE ADJUSTMENT BASED ON A SINGLE RESULT IS EXTREMELY UNLIKELY. NEVERTHELESS, SIEMENS ISSUED AN URGENT MEDICAL DEVICE RECALL COMMUNICATION 13-90 TO CUSTOMERS WHO HAD ORDERED THESE LOTS ADVISING THEM TO DISCONTINUE USE AND TO DISCARD THE LOTS. SIEMENS OFFERED ALTERNATE NON-IMPACTED LOTS FOR CUSTOMER REPLACEMENTS.
