The Stool Osmolar/Osmotic Gap determines if chronic diarrhea is osmotic or secretory in nature.

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 …

2017年9月7日 · Stool osmotic gap = Stool osmolality - 2 x (stool Na + stool K) Normal fecal fluid values : Osmolality : ~290 mOsm/kg Na+ : ~30 mmol/L K+ : ~75 mmol/L Stool Na : meq/L …

This stool osmotic gap calculator checks whether diarrhea is of a secretory or osmotic cause and provides the osmolar gap in mOsm/Kg.

2024年1月27日 · The osmotic gap is determined by calculating the 290 mOsm/kg – 2 x (stool sodium + stool potassium) ratio, which is the presumed stool osmolality and the measured …

*—Fecal osmotic gap = 290 – 2 . × (stool sodium + stool potassium). It helps differentiate secretory from osmotic diarrhea. Normal fecal osmolality is 290 mOsm per kg (290 mmol per kg).

This stool osmotic gap calculator discriminates between secretory and osmotic diarrhea based on the osmolar gap in mOsm per kg.

• Fecal Leukocytes: indicates inflammatory diarrhea (sensitivity=42- 73%, specificity=84%); if (+); send stool culture. – In C. difficile colitis, has sensitivity of 30% & specificity of 75% …

The fecal fluid usually has elevated electrolytes (primarily sodium and chloride) and a low osmotic gap (<50 mOsm/kg). Infection is a common secretory process; however, it does not typically …

2024年5月5日 · The stool osmotic gap is defined as the difference between the measured osmolality and a calculated osmolality (2*([fecal Na+] + [fecal K+]). A stool osmotic gap <50 …
