Discordant, falsely elevated potassium (k) results were obtained on one patient sample on a dimension vista 500 instrument. The initial discordant result was reported to the physician(s), who questioned whether the sample was hemolyzed. The customer discovered that it was not properly hemolyzed. The sample was repeated on the same instrument and on an alternate instrument, resulting lower on the alternate instrument. The patient was redrawn and the new sample was tested on the alternate instrument, resulting as expected. The corrected result was reported to the physician(s). There are no reports of patient intervention or adverse health consequences due to the discordant, falsely elevated k results.

The customer contacted the siemens technical solutions center (tsc). A global product support (gps) specialist evaluated the instrument data and did not find an instrument malfunction. The cause of the discordant, falsely elevated k results is unknown. It was discovered that the customer was centrifuging patient samples outside of the tube manufacturer specifications. The cause of the samples being centrifuged outside of tube vendor specifications is failure to follow instructions. The instrument is performing according to specifications. No further evaluation of the device is required.
