    Description of Event or Problem · 1

    WHILE CONDUCTING AN INVESTIGATION AND INFORMATION GATHERING FOR MEDWATCH #1061932-2012-00155, A BEC FIELD AGENT FOUND EVIDENCE ON (B)(6) 2012 OF ERRONEOUS HIGH MEAN CORPUSCULAR VOLUME (MCV) GENERATED ON UNICEL DXH 800 COULTER CELLULAR ANALYSIS SYSTEM WITH NO INSTRUMENT GENERATED FLAGS ON 6 SPECIFIC PATIENT SAMPLES WHICH WERE RUN ON THREE DIFFERENT DAYS. UPON REVIEW OF INSTRUMENT PRINTOUTS, IT WAS FOUND THAT FIVE OF SIX RED CELL DISTRIBUTION WIDTH (RDW) PATIENT RESULTS WERE ALSO ERRONEOUSLY HIGH AS COMPARED TO THE LH 500. CUSTOMER INDICATED THAT ALL 6 PATIENT SAMPLES WERE REPEATED ON THE LH 500 HEMATOLOGY ANALYZER ON THE SAME DAY THE ERRONEOUS RESULTS WERE GENERATED AND THE CORRECTED REPORTS WERE REPORTED OUT OF THE LAB. CUSTOMER STATED THAT NO ERRONEOUS RESULTS WERE REPORTED OUTSIDE THE LABORATORY AND NO CHANGE TO PATIENT TREATMENT WAS ATTRIBUTED TO THIS EVENT. CUSTOMER REPORTED OF ONGOING ISSUES WITH THE DXH 800 GENERATING ERRONEOUS MCV VALUES ON SPECIFIC PATIENTS WHICH WERE NOT PASSING THE DELTA CHECK OF PATIENT RESULTS PRIOR TO IMPLEMENTATION OF THE UNIT. CUSTOMER INDICATED THAT OCCASIONALLY, THE RESULTS ALSO DISPLAY AN H&H (HEMOGLOBIN & HEMATOCRIT) CHECK FAILED MESSAGE. A SIMILAR EVENT WERE REPORTED BY CUSTOMER ON (B)(6) 2011 (MEDWATCH #1061932-2012-00155) AND THIS REPORT IS CREATED AS A RESULT OF AN INVESTIGATION FOR THAT EVENT. THIS REPORT IS FOR THE EVENT WHICH OCCURRED ON (B)(6) 2011. PLEASE SEE MEDWATCH #1061932-2012-00267 AND #1061932-2012-00268 FOR THE REPORT ON THE OTHER 5 PATIENTS. ERRONEOUS RESULTS OF 94.6 MCV AND 14.7 RDW WERE GENERATED FOR PATIENT 1 ON (B)(6) 2011 FROM THE DXH 800. THE SAMPLE WAS RERUN ON LH 500 AND RESULTS OF 91.6 MCV AND 14.0 RDW WERE OBTAINED. CUSTOMER DETERMINED THAT THE LH 500 RESULTS WERE CORRECT AND WERE REPORTED OUT OF THE LAB.
