    THE SAMPLES WERE COLLECTED IN NEW SARSTEDT MONOVETTE EDTA 2.6ML TUBES, WHICH HAVE NOT BEEN APPROVED FOR USE ON THE COULTER AC-T DIFF 2 ANALYZER. QC WAS RUN BEFORE AND AFTER EACH INCIDENT WITHIN RANGE AND INSTRUMENT IS CURRENTLY PERFORMING WITHIN QC SPECIFICATION. A FIELD SERVICE ENGINEER (FSE) WAS DISPATCHED ON (B)(4) 2011, FOR THIS EVENT. THE FSE INSPECTED THE INSTRUMENT, ADJUSTED THE PROBE ALIGNMENT, VERIFIED THE VACUUM AND CLEANED THE BATHS. QC WAS PERFORMED AND REVIEWED, WHICH ALL LEVELS RESULTED WITHIN SPECIFICATION. A STARTUP AND REPRODUCIBILITY WAS ALSO PERFORMED BY THE FSE, WHICH PASSED. THE ROOT CAUSE FOR THE LOWER PLT, RBC AND HIGHER MCV RESULTS IS UNKNOWN; HOWEVER, THE CUSTOMER IS USING A COLLECTION DEVICE THAT HAS NOT BEEN APPROVED FOR USE ON THE ACT DIFF 2 INSTRUMENT WHICH COULD BE THE CAUSE OF THE ERRONEOUS RESULTS. PER LABELING, BECKMAN COULTER NEITHER RECOMMENDS THE USE OF ONE SAMPLE TUBE IN PREFERENCE TO ANOTHER NOR GUARANTEES THE ACCEPTABILITY OF THE SAMPLE TUBE TO PRODUCE QUALITY RESULTS.
