Background Anion gap (AG) aids the differential diagnosis of acid-base disorders. Its value
has decreased, because of new analytical methods. Our goal was to compare AG reference …

Background The anion gap is primarily used in the diagnosis of acid-base disorders. We
conducted a study to determine the anion gap reference interval in our patient population …

Background: Conflicting data exist as to what extent hypoalbuminemia reduces the anion
gap; estimates range from 1.5 to 2.5 mM per g/dL decrease in serum albumin. Methods: We …

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 …

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 …

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 …

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 …

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

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 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 …
