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)
