What is Diamine Oxidase (DAO)?
The Diamine Oxidase (DAO) test measures the activity of the DAO enzyme in your blood. This enzyme is primarily responsible for breaking down histamine from food in your digestive tract. Low DAO activity can lead to a buildup of histamine.
Why is this test important?
This test is important for individuals experiencing symptoms of histamine intolerance, such as digestive issues, skin rashes, headaches, or nasal congestion after consuming histamine-rich foods. It helps identify if low DAO levels are contributing to these reactions.
How to Prepare
Fasting for at least 8 hours is usually recommended before this test. Avoid alcohol and certain medications as advised by your doctor.
