Calculating Plasma Osmolality and Osmolal Gap



Calculated Osmolality = 2 x Na  + Glucose/18 + BUN/2.8 + EtOH/4.6



Osmolal Gap = Calculated Osmolality - Measured Osmolality



Causes of Elevated Osmolal Gap (>10):

- Toxic Alcohols (Ethylene Glycol, Methanol, etc)

- Isopropyl Alcohol

- Mannitol

- Acetone (ketoacidosis)
