The anion gap in the serum is useful in the interpretation of acid-base disorders and in the
diagnosis of other conditions. In the early 1980s, ion-selective electrodes for specific ionic …

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

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 …

Anion gap (AG) is a calculated value commonly used in clinical practice. It approximates the
difference between the concentration of unmeasured anions (UA) and unmeasured cations …

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 serum anion gap has been utilized to identify errors in the measurement of electrolytes,
to detect paraproteins, and, most relevant to the nephrologist, to evaluate patients with …

Discussion DR. PATRICIA A. GABOW (Director, Medical Services, Den-ver General
Hospital, Denver, Colorado): The anion gap is a concept based on the electrically neutral …

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 …

Background The purpose of this review is to provide a differential diagnosis for a low anion
gap. Methods We describe the anatomy of the anion gap. Also, we follow-up with a review of …

The plasma concentration of sodium ions normally exceeds the sum of the plasma
concentrations of chloride and bicarbonate ions. Calculation of the resulting'anion gap'can …
