CLINICAL USE OF THE ANION GAP

EMMETT, MICHAEL, NARINS, ROBERT G.·1977·Medicine

Abstract

The concepts underlying the clinical use of the anion gap (AG) and those disorders associated with its alteration are reviewed. A substantial increase in the AG usually indicates the presence of a metabolic acidosis, unless large doses of certain antibiotics or sodium salts of organic acids are being used. The etiology, pathogenesis and diagnosis of high AG metabolic acidoses are discussed. Stress is placed upon the utility of the AG in defining the cause of the acidosis, and as a guide to therapy in certain organic acidoses. A decrease in the normal AG occurs in dilutional states, hypoalbuminemia, hypercalcemia, hypermagnesemia, hypernatremia, diseases associated with hyperviscosity, bromide intoxication, and in certain paraproteinemias. The important clue provided by a low or negative AG in the diagnosis of certain of these life-threatening disorders is emphasized.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
