WebNov 3, 2024 · A normal osmolar gap is <10. The small gap is present due to the calculation not taking into account chloride, potassium, sulphate, phosphate, calcium, magnesium, lactate, ammonia, serum proteins and lipids. In toxicology ethanol is fairly common to our presentations so the osmolarity formula routinely used is: WebCalculated 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 …

WebNov 9, 2024 · What is the formula for calculating osmolality? In order to calculate the osmolal gap, tests for blood sodium, blood urea nitrogen (BUN), and glucose must be performed to calculate the expected osmolality. Some versions of the expected osmolality calculation also include the measurement of ethanol. An example calculation is: WebTo calculate plasma osmolality use the following equation (typical in the US): = 2 [ Na+ ] + [Glucose]/18 + [ BUN ]/2.8 [8] where [Glucose] and [BUN] are measured in mg/dL. If the patient has ingested ethanol, the ethanol level should be included in the calculated osmolarity: = 2 [ Na+ ] + [Glucose]/18 + [ BUN ]/2.8 + [Ethanol]/3.7 [8]
