Stool Osmolar/Osmotic Gap - MDCalc

WebStool contains water, electrolytes and solutes. The fecal osmotic (or osmolar) gap measures the differences between measured fecal osmolality and concentrations of electrolytes in the stool, and it indicates the concentration of poorly absorbed solutes in the feces. This can provide useful information in patients with diarrhea. WebStool osmolality is measured in milliosmoles per kilogram (mOsm/kg). It normally ranges from 275 to 295 mOsm/kg. Stool osmolality less than 250 mOsm/kg may suggest factitious diarrhea. How is this test done? This test is done with a stool sample. You will likely be asked to give a random or a timed liquid stool sample. tangerine heloc https://cliveanddeb.com
