Dubowski KM. Manual of Analysis of Ethanol in Biological Fluids. NHTSA. DOI: 10.21949/1402615. PMID: 12214776. Scope: each 1 mg/dL of ethanol increases measured serum osmolality by approximately 0.217 mOsm/kg, equivalent to dividing ethanol concentration (mg/dL) by 4.6 to estimate osmolal contribution (mOsm/kg).
