Osmol Gap Calculator

Serum Osmolarity Calculation

Osmol gap in medical science is the difference between measured serum osmolality and calculated serum osmolality.

The reference range of serum osmolality is 275–295 mosm/kg (mmol/kg).

This calculator calculates the osmolality using sodium, glucose, urea values.

Formula:

Serum Osmolarity=2×Na+GLU+URE

Where,

Na is the Sodium
GLU is the Glucose
URE is the Urea
