The panel includes four markers: zonulin, histamine, DAO, and the histamine to DAO ratio. Elevated zonulin suggests leaky gut by loosening tight junctions, while histamine can be associated with symptoms like headaches, hives, nasal congestion, anxiety, and irregular heart rate. DAO is the enzyme that clears histamine and is also tied to gut lining integrity, and the histamine to DAO ratio is described as the most important number for assessing intolerance.
