From the data received, it appeared that the sodium and chloride sensors were functioning properly.The patient sample had higher recovery for sodium chloride and potassium on system 31408 when compared to the sample run on system 31508.Most likely the sample run on (b)(6) 2016 at 12:37 on system 31408 was pre-analytical; due to the presence of salt being introduced to the sample from the sample port/luer area ahead of the sample.There is no evidence that the sensors were malfunctioning since there was no sodium drifts on the day of the event and 1 chloride drift 5 hours before the sample in question was run.
