Component code: g03001.Abbott field service (fs) was requested for some maintenance after the issue.There were no additional discrepant results reported on the cell-dyn emerald, serial number (b)(6), after the service.A patient sample was not repeated on cell-dyn emerald and was sent to another lab and tested 3 hours later on an unknown analyzer.This unknown instrument was a 5-part differential analyzer which was different from the 3-part differential instrument like cell-dyn emerald.Results generated by the unknown analyzer were lower for wbc, rbc, hgb, mcv and hct, and higher for plt.Wbc differential also did not match the cell-dyn emerald results, but due to the different technologies, a direct comparison between cell-dyn emerald and this analyzer could not be made.The manual reading on wbc differential was also not exactly matched to either cell-dyn emerald or this unknown analyzer.Overall, the actual patient results could not be confirmed from the data provided in this ticket.The blood collection tube type was unknown, but it was likely a capillary sample.If the sample volume was very small, and/or if sample mixing was harder due to low sample volume, then count-to-count variation might potentially occur.Cell-dyn emerald only allowed open mode testing, and it was unknown which mode (open or closed if it could be chosen) was used on the other analyzer.A review of the manufacturing documentation did not identify any issues associated with the complaint issue.A review of labeling concluded that the issue is sufficiently addressed.Based on the investigation no systemic issue or deficiency of the cell-dyn emerald analyzer serial number (b)(6) was identified.
