http://www.clinlabnavigator.com/osmolality.html WebbOsmolal gap = Measured – calculated osmolality. Normal osmolal gap: < 10 mOsm/kg. High osmolal gap: > 10 mOsm/kg. This indicates the presence of unmeasured osmoles (“unmeasured” in terms of the calculation) e.g. ethylene glycol, mannitol or false decreases in sodium or pseudohyponatremia, e.g. marked hyperlipemia or hyperproteinemia.

Isopropyl alcohol causes an osmolal gap but does NOT cause AG metabolic acidosis. As toxic alcohol is metabolized, anion gap will increase as osmolal gap slowly decreases -- so an elevated anion gap with low osmolal gap can be seen in late phase of …
