WebStool sodium: normal value of 30 mEq/L. Stool potassium: normal value of 75 mEq/L. Stool osmolarity: this is not directly measured but given a constant in the range of 290 to 300 mOsm/kg. Most of the osmotic activity of stool comes from electrolytes. 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…
