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 …

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 …

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 …

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 …

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 …

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 …

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 …

The anion gap is a calculated parameter derived from the difference between the major
plasma cations and anions in serum/plasma or whole blood, with a widely used simple …

The serum anion gap, calculated from the electrolytes measured in the chemical laboratory,
is defined as the sum of serum chloride and bicarbonate concentrations subtracted from the …
