Anion gap acidosis
Osm gap (measured - calculated)
Calculated serum osm = 2Na + BUN/2.8 + glucose/18 +<unk> /4.6
Normal is < 10
Note: Cannot rule out toxic ingestion with a "normal" osmol gap
Only parent alcohol is osmotically active
Delayed presentation may mean that much of it is already metabolized
