Plasma potassium measurement with a new reagent carrier (Reflotron): comparison with ion-selective electrode results.
Potassium concentrations were measured in the plasma of 336 animals with a new reagent carrier (Reflotron; Boehringer Mannheim) K+ and with an ion-specific electrode system: results were highly correlated (r = 0.991; y = 0.993 x + 0.02) and day-to-day coefficient of variation of the new reagent measurements was lower than 2.5 per cent. This system offers a good alternative to the ion-selective electrode system for plasma potassium measurement in veterinary practice.
