Histamine & DAO Gut Health Full Blood Test UK | Gut Balance Check

Package Options
 

Feeling bloated, tired, itchy-skinned or sluggish without a clear cause? This Histamine / DAO Gut Health Full Blood Test helps uncover whether a histamine imbalance or reduced diamine oxidase (DAO) activity could be behind your symptoms. DAO is the enzyme your body uses to break down histamine, so when it’s low, histamine can build up and affect digestion, skin and overall comfort.

This full blood test doesn’t just look at histamine and DAO — it also checks zonulin and lipopolysaccharide (LPS) markers to help you understand gut barrier health. It’s ideal if you’re experiencing ongoing digestive issues, headaches, skin irritation or general discomfort that might be linked to histamine intolerance.

✅ Evaluate zonulin, DAO, and LPS biomarkers for diagnosing gut permeability.
✅ Aids in diagnosing intestinal permeability, commonly known as "leaky gut".
