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 …

A simple model for the simulation of patient Na, CO2, Cl, and anion gap was formulated from
patient electrolyte data. Analytical error, either random or systematic, was incorporated into …

Because the anion gap is useful in classifying acid-base disorders, quantitative information
on this variable should be readily available. Three populations were studied and means and …

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 …

• Using modern electrode technology (Beckman ASTRA analyzer), we evaluated the
reference range for the anion gap (calculated as sodium minus chloride minus bicarbonate …

A new programmable microprocessor-controlled multichannel chemistry analyzer, the
Beckman® ASTRA 4, was evaluated in an electrolyte configuration including sodium …

When compared with results obtained by the authors in a department of medicine, the
values obtained by three hospital laboratories for sodium, potassium, and chloride in normal …

We report the incidence of normal (50.4%), increased (46.7%), and decreased (2.9%) anion
gap among hospitalized patients in a retrospective study. The mean and range of increased …
