The" anion gap" refers to the concentration of unmeasured anions in blood. The most
commonly used formula to measure this is [Na]—[C1]—[HCO3] and a typical reference …

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 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 …

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 …

Objective.—To review limitations of the use of serum anion gap in clinical practice. Data
Sources.—Original reports and reviews. Study Selection.—Sources containing the most …

The anion gap (AG) in the serum equals the concentrations of Na-(Cl+ HCO3). It is
becoming increasingly useful in the interpretation of acid-base disorders and in the …

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 …

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 …

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 …

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 …
