Background We compared the effect of haemolysis in sodium measurement using indirect
and direct ion-selective electrodes to test the hypothesis that haemolytic effect on sodium …

When the reference electrode liquid junction of a Nova 2 analyser was changed to isotonic
potassium chloride, increasing the ionic strength of aqueous solutions containing a constant …

Background The anion gap is primarily used in the diagnosis of acid-base disorders. We
conducted a study to determine the anion gap reference interval in our patient population …

Materials and Methods: In this prospective study, electrolytes were analyzed in 44 paired
samples drawn from critically ill patients. Whole blood electrolytes were analyzed using a …

Introduction: Measurement of electrolytes plays a significant role in the management of
critically ill patients. The accuracy of electrolyte measurement depends on a number of pre …

Method Sodium and potassium concentrations were measured in both whole blood and
plasma from a series of 21 patient samples using a Corning 902 ISE. The difference …

With electrolyte reference fluid (ERF) 00, results from Kodak Ektachem slides for the direct
potentiometric assay of sodium in plasma were significantly correlated with results from …

Sixty-seven thousand seven hundred forty consecutive sets of electrolyte levels measured at
the Massachusetts General Hospital were reviewed, and their anion gaps were calculated. A …

To determine the concentration of ionized calcium (iCa) collected in lithium heparin and gel
tubes and to correlate the measured iCa with calculated iCa. Anaerobic fasting blood …

Abstract The Beckman Electrolyte 2 Analyzer (E2A) has been studied for its response to
sodium and potassium content in various laboratory prepared pH-adjusted mixtures of metal …
