Department of Emergency Medicine, Albany Medical College, New York 12208.

A retrospective review of 81 emergency department patients was performed to determine the accuracy of blood ethanol levels (BEL) calculated from serum osmolality. The osmolar gap (measured-calculated serum osmolality) was used to determine the calculated BEL. The mean difference between calculated and measured BEL was 49.2 mg/dL. Calculated BEL overestimated measured BEL in 83% of patients. Adding a correction factor for unmeasured osmoles to the equation for calculated serum osmolality will reduce this error.

D000431	Ethanol	A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
