The Histamine in Stool test is designed to measure the level of histamine in the stool, which can indicate histamine intolerance or an IgE-mediated food allergy. Elevated histamine levels may result from impaired production of Diamine Oxidase (DAO), chronic inflammatory gastrointestinal conditions like celiac disease or Crohn's disease, food intolerances (IgG), or stress-related mast cell breakdown.
Difference Between Histamine in Stool and Blood DAO Test
It's important to understand the difference between this stool test and a blood-based histamine intolerance test, which measures DAO enzyme activity. The blood test evaluates the body’s ability to break down histamine, whereas the Histamine in Stool test measures histamine levels directly within the digestive system. This provides specific insights into gastrointestinal-related histamine issues, which the blood test does not address.
