Is it possible that I get different results from histamine intolerance tests of other providers?

The short answer is: Yes, it is possible. Why?

With our histamine test we measure the degradability of histamine in dry blood via the enzyme diamine oxidase.

Our test provides an indication of a possible reduced main degradation in the intestine via the DAO, although there are also other degradation pathways of histamine (via the histamine N-methyltransferase). Therefore, our results speak of a possible histamine intolerance.

The test result must always be seen in connection with possible symptoms. The DAO level measured by the histamine test can be influenced by the following factors:

“DAO inhibitors”, such as DAOsin
nicotine and
Medication (N-acetylcysteine, ambroxol, aminophylline, amitriptyline, chloroquine, clavulanic acid, isoniazid, metamizole, metoclopramide, propafenone, verapamil and others).
Some of these drugs do not specifically affect DAO, but only histamine release. In general, the influence of drugs on DAO is not 100% guaranteed.

Certain foods are also suspected of influencing DAO levels – including cocoa, green and black tea and energy drinks.

The supply of vitamin B6, zinc and vitamin C also has an influence on DAO levels, as DAO cannot be produced sufficiently in the event of a deficiency.
