Osmolal Gap

Preparation Tips regarding MCQs and PG Entrance Exams

Osmolal Gap is the difference between measured serum osmolality and calculated serum osmolality.

It is typically calculated as: OG = measured serum osmolality – (2 X serum sodium + serum glucose + serum urea)

Where:

* 2 X serum sodium + serum glucose + serum urea = the calculated serum osmolality and all measures [...

Preparation Tips regarding MCQs and PG Entrance Exams

Blood has a lot of Cations Blood has a lot of Anions

Total charge of Anions = Total Charge of Cations

So

Na + K + Unmeasured Cations = HCO3 + Cl + unmeasured AnionsRearrangingNa + K – (HCO3 + Cl) = Unmeasured Anions – Unmeasured CationsAnion Gap = Unmeasured Anions – Unmeasured Cations
