Histamine/ DAO Gut Health - Full Blood Test
Histamine/ DAO Gut Health - Full Blood Test
The Histamine / DAO Gut Health Full Blood Test is designed to uncover whether histamine imbalance could be affecting your wellbeing. By measuring histamine alongside diamine oxidase (DAO) enzyme activity, this test highlights how effectively your body breaks down histamine — a compound that can impact digestion, skin health, immunity, and energy.
This test is particularly helpful for those experiencing symptoms such as bloating, digestive upset, headaches, skin irritation, or fatigue that may be linked to histamine intolerance. This gives you the knowledge to take steps towards restoring gut balance and improving daily comfort.
✅ Evaluate zonulin, DAO, and LPS biomarkers for diagnosing gut permeability.
✅ Aids in diagnosing intestinal permeability, commonly known as "leaky gut".
