The investigation determined that results for two different patient samples were associated with the incorrect sample id (sid) when run on a vitros eci immunodiagnostic system.The assignable cause of the event was user error when entering a sid number into the system.The customer erroneously entered a sid number into the system that had no corresponding physical sample.The sample program for this sid remained in the memory of the vitros eci immunodiagnostic system.Two different operators on two separate dates erroneously entered the retained sid number for samples which had alternative sid numbers.When each of these samples were processed, the results were mis-associated with the retained sample id number.The customer confirmed that the issue was due to user error and that no erroneous results were reported out of the laboratory.The vitros 5600 integrated system did not malfunction.
