Serum Osmolality and Osmolal Gap Calculator
Serum Osmolality and Osmolal Gap: a planned Super Calculator tool. Covers sodium (mmol/L). Stub page while the tool and its worked example are prepared.
Serum Osmolality and Osmolal Gap Calculator is a planned calculator in the health section of Super Calculator, covering clinical dosing and scores.
What this calculator will compute
Inputs: sodium (mmol/L), glucose (mg/dL or mmol/L), urea or BUN, ethanol and measured osmolality.
Outputs: calculated osmolality (mOsm/kg) and osmolal gap.
Formula, recorded as scope and not yet verified against a primary source: Calculated osmolality = 2*[Na] + glucose/18 + BUN/2.8 in conventional units, or 2*[Na] + glucose + urea in mmol/L in SI units, with an ethanol term of ethanol in mg/dL divided by 3.7 where relevant. Osmolal gap = measured minus calculated.
