    THE INVESTIGATION CONCLUDES THAT HIGHER THAN EXPECTED SODIUM (NA+) RESULTS WERE OBTAINED WHEN PROCESSING VITROS PERFORMANCE VERIFIER I, LOT Q1174 ON A VITROS XT 7600 INTEGRATED SYSTEM. THE DEFINITIVE CAUSE COULD NOT BE CONFIRMED. A REVIEW OF HISTORICAL QC RESULTS PRIOR TO THE DAY OF THE EVENT INDICATED SOME PRECISION ISSUES USING VITROS NA+ LOT 4212-1097-6150. THEREFORE, A VITROS NA+ REAGENT ISSUE COULD NOT BE RULED OUT AS A POTENTIAL CONTRIBUTING FACTOR. AN ORTHO FIELD ENGINEER PERFORMED SERVICE ACTIONS TO THE VITROS XT 7600 SYSTEM AND FOLLOWING SERVICE THE CUSTOMER OBTAINED ACCEPTABLE VITROS NA+ LOT 4212-1097-6150 RESULTS WITHOUT A RECALIBRATION. TWO DAYS AFTER THE SERVICE EVENT, A WITHIN RUN PRECISION WAS PERFORMED AND THE PRECISION RESULTS WERE ACCEPTABLE INDICATING THE VITROS XT7600 INTEGRATED SYSTEM WAS PERFORMING AS EXPECTED. HOWEVER, AS THERE WAS NO PRE-SERVICE PRECISION TEST PERFORMED TO ASSESS THE PERFORMANCE PRIOR TO SERVICE, AN ISSUE WITH THE VITROS XT7600 SYSTEM COULD NOT BE ENTIRELY RULED OUT AS A CONTRIBUTOR OF THE EVENT. A POSSIBLE CAUSE OF THE HIGHER THAN EXPECTED VITROS NA+ RESULTS WHEN PROCESSING PERFORMANCE VERIFIER I CONTROL FLUID IS A PRE-ANALYTICAL SAMPLE PROGRAMMING ERROR, HOWEVER, THIS COULD NOT BE DEFINITIVELY CONFIRMED. A REVIEW OF ECONNECTIVITY DATA SHOWS THE CUSTOMER ROUTINELY PROCESSES THE LEVEL 1 CONTROL IN THE MORNING AND THE LEVEL 2 CONTROL IN THE EVENING. IT IS SUSPECTED THE EVENING CUSTOMER PROGRAMMED THE LEVEL 2 CONTROL USING THE LEVEL 1 SAMPLE NAME ¿KOD1¿ IN ERROR. THE DATA SHOWS THE CUSTOMER REPEATED THE LEVEL 2 CONTROL CORRECTLY USING THE LEVEL 2 SAMPLE NAME OF KOD2 AND OBTAINED RESULTS REPRESENTATIVE OF A LEVEL 2 CONTROL.
