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 … birding south floridaWebb1 jan. 2016 · The osmolal gap refers to the difference between the measured and calculated osmolality of serum or urine.
