Stool osmotic gap is a measurement of the difference in solute types between serum and feces, used to distinguish among different causes of diarrhea. Feces is normally in osmotic equilibrium with blood serum, which the human body maintains between 290–300 mOsm/kg. However, the solutes contributing to this total differ. Serum is mostly sodium and potassium salts (as reflected in the formulas for serum osmol gap and anion g… WebOsmotic gap is calculated as 290 mOsm/kg- (2 [Na]+2 [K]). Typically, stool osmolality is similar that seen in serum since the gastrointestinal (GI) tract does not secrete water. (1) An osmotic gap above 50 mOsm/kg is suggestive of an osmotic component contributing to the symptoms of diarrhea. (1,5,7)
