Abstract
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.
