Normal osmolarity gap
WebNormal serum osmolality is 280 to 310 mosm/kg, and the normal osmole gap is less than 10 mosm/kg. Serum osmolality as high as 450 mosm/kg serum and an osmole gap as high as 150 mosm/kg serum may be seen 3 hours after ingestion, depending on the quantity of antifreeze ingested. 34,70 Both the gap and the measured osmolality may remain … WebAn increase in serum osmolality and serum osmolal gap with or without high-anion-gap metabolic acidosis is an important clue to exposure to one of the toxic alcohols, which include methanol, ethylene glycol, diethylene glycol, propylene glycol, or isopropanol. However, the increase in serum osmolal …
