Osmolgap en ethanolspiegel
The osmol gap is typically calculated as:
OG = measured serum osmolality − calculated osmolalityCalculated osmolality = 2 x Na + Glucose + Urea. (all values in mmol/L)
In non-SI laboratory units: Calculated osmolality = 2 x [Na mmol/L] + [glucose mg/dL] / 18 + [BUN mg/dL] / 2.8 + [Ethanol/3.7][3] (note: the values 18, 2.8 and 3.7 convert mg/dL into mmol/L)
A normal osmol gap is < 10 mOsm/kg .[4]
