The real value of the budget available for clinical chemistry in this country is unlikely to
increase for some years. Any expansion and development must therefore be balanced by …

The authors have shown previously that averaging at least eight patient anion gaps provides
a sensitive technic for the detection of systematic error in electrolyte analysis (Am J Clin …

Blood electrolyte concentrations are tightly controlled by homeostatic mechanisms, with a
very low intraindividual biological variability [1]. To be clinically useful, measurement results …

The traditional anion gap [AG= Na–Cl–(total CO2)] mean value of 12 mEq/L was established
during the 1970s with analyzer methods that are no longer used widely. No studies have …

The determination of electrolytes in human body fluids is one of the most frequently
performed analyses in clinical routine laboratories. Metrological traceability of measurement …

Evidence Is presented that pH measurements of blood plasma and otherclinical media at an
Ionic strength (I) of 0.16 vs. the NBS standards may Involve residual liquid-junction errors …

We measured the emf of a sodium ion-selective electrode in NaCl-NaHCO3 solutions (160
mmol of Na+, 160-120 mmol of Cl-, and 0-40 mmol HCO3-per liter) with a home-built cell in …

The Scientific Division Committee on pH, Blood Gases and Electrolytes of the International
Federation of Clinical Chemistry (IFCC) pröduced recommendations to attempt to make the …

Background Levels of serum sodium (Na) are widely determined in clinical laboratories.
Accordingly, sodium quantification must be performed using reliable methods. Herein are …

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 …
