DAO enzyme test

DAO enzyme test

The DAO enzyme test, also known as the DAO deficiency test, is a tool designed to measure the level of Diamine Oxidase (DAO) enzyme in your body. DAO is essential for breaking down histamine in food and drinks, a compound found in certain foods and produced by the body during allergic reactions. When DAO levels are low, histamine may accumulate, potentially leading to symptoms like headaches, hives, digestive discomfort, and more.

For individuals experiencing symptoms related to histamine intolerance, the DAO enzyme test provides valuable insights. The test, often performed as a DAO blood test, determines whether a deficiency in DAO may be contributing to these symptoms. It can help individuals and healthcare providers better understand the role of histamine in their health and guide dietary adjustments or supplement choices.

A DAO deficiency test can be particularly useful for those who suspect they have a histamine intolerance or are struggling with unexplained allergic-like symptoms that are unresponsive to traditional allergy treatments. By identifying low DAO levels, individuals can make more informed choices about their diet and lifestyle, potentially reducing discomfort. Before doing a DAO blood test, you can take an online intolerance test for more information:

If your intolerance test reveals that histamine-rich foods trigger your symptoms, consider trying a DAO supplement, such as DAO Plus. DAO Plus supports healthy degradation of food-derived histamine.*
