Reference ranges have not been established. However, Fecal Osmotic Gap in mOsm/kg can be calculated using the following equation: Fecal Osmotic Gap = 290 - 2x ([Na] + [K]). A Fecal Osmotic gap of 125 mOsm/kg or greater is indicative of osmotic diarrhea, whereas a result of 50 mOsm/kg or less indicates secretory diarrhea.
