Can Clatra affect the outcome of the DAO test?

There is no information in the product characteristics that bilastin, a substance in Clatra, affects the results of specific studies. However, it is an antihistamine, and the DAO test is performed to determine the serum concentration of diamine oxidase (DAO) - an enzyme that is responsible for removing histamine from the body. Therefore, it cannot be excluded that the results of the study when using the drug may be disturbed. If the drug is not effective, I encourage you to visit a doctor - perhaps he will change the treatment or, for example, check whether the cause of your ailment lies somewhere else. Rashes or urticaria can have a different background, it is also worth taking care of proper skin care. Where can you order cosmetics for problematic skin, e.g. https://www.gdziepolek.pl/produkty/104230/la-roche-posay-lipikar-baume-apm-balsam-do-ciala-balsam/apteki?pvid=254149#internetowe lotion or soothing thermal water: https://www.gdziepolek.pl/produkty/25933/avene-woda-termalna-aerozol/apteki#internetowe
