The CNS DAO Screen uses a dry blood spot method to detect the concentration of the DAO enzyme within the blood, which is responsible for breaking down histamine.
Histamine is a chemical that is released from mast cells during an allergic reaction, but it also occurs naturally in certain histamine-rich foods. Other foods, although low in histamine themselves, can also encourage the release of histamine within the body.
