LaboratoryOsmol gap of Stool
Definition
Stool osmotic gap is calculated to evaluate the cause of chronic diarrhea. It is the difference between measured and calculated stool osmolality. A low stool osmotic gap can imply secretory diarrhea due to various causes, including cholera, vasoactive intestinal peptide, laxative abuse, and gastrinoma. A high gap can imply osmotic diarrhea possibly due to chronic pancreatitis, lactase deficiency or Whipple's disease.
