Customer advised they are experiencing intermittent occurrences of elevated potassium.They have been running specimens on two analyzers to see if it was an issue with the analyzer but the elevated results are the same on both analyzers.All collections are different phlebotomist from different areas of the hospital.Re-draws are all within normal range.The centrifuge is a statspin express 2 with the horizontal spin for flat gel separation.Centrifuge speed is checked every 6 months and spins at 8500 rpm (4400g).Gel barriers are properly formed with no sign of cells leaking into the plasma.Plasma is not hemolyzed.Customer advises they follow proper phlebotomy practices.They are a stat lab so tubes go into centrifuge within 5 minutes of draw but they do not have a pneumatic tube system.
