Histamine intolerance DAO measurement<\/h1>\n\t
\n\t\t
\n\t\t\t

Histamine intolerance is a combination of symptoms after consuming foods high in histamine.<\/p>\n

Histamine is partly produced by our body and partly contained in our food. An enzyme called DAO (diamino oxidase) is responsible for breaking down histamine. In the absence or reduced function of the enzyme, its breakdown slows down significantly and histamine builds up in the body, producing allergy-like symptoms after consuming a food rich in histamine.<\/p>\n

Clinical symptoms are caused by persistently high histamine concentrations.<\/p>\n

Consumption of foods and medications that inhibit histamine breakdown or cause histamine release, as well as non-fresh foods, can also cause complaints.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Most common symptoms<\/h2>\n\t
\n\t\t
\n\t\t\t

Respiratory symptoms<\/p>\n

runny nose, sneezing, cough, shortness of breath<\/p>\n

Digestive problems<\/p>\n

Foods causing histamine intolerance:<\/h2>\n\t
\n\t\t
\n\t\t\t

chocolate, cocoa
\nbeer
\nchampagne
\nred wine (the more mature the wine, the higher the histamine content)
\npreserved vegetables
\nsour cabbage
\ntomatoes, ketchup (pizza can be a problem too!)
\nvinegar and foods containing vinegar (e.g. mustard)
\nfish products, in particular canned fish, crab, snails, scallop, octopus
\noffal, smoked meat, sausages, ham
\nlong-ripening „hard” cheeses (the longer the ripening time, the higher the histamine content)<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

\n\t\t
\n\t\t\t

Foods and drugs that inhibit histamine breakdown or cause histamine release<\/p>\n

pineapple
\npapaya
\navocado
\nwalnut
\ndrugs: diclofenac, aspirin
\niodinated contrast agent<\/p>\n

Not fresh foods in which histamine-producing bacteria have multiplied.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Laboratory method<\/h2>\n\t
\n\t\t
\n\t\t\t

During the assay, the concentration of DAO enzyme is measured by an ELISA-based test.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Interpretation of the results<\/h2>\n\t
\n\t\t
\n\t\t\t

Decreased DAO levels make histamine intolerance likely. Measured results should always be evaluated with clinical symptoms.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Preanalytical information<\/h2>\n\t
\n\t\t
\n\t\t\t

Native serum is required for testing. The test is not affected by taking antihistamines.
\nThe test is influenced by various drugs, muscle relaxants, narcotics, painkillers, antihypertensive drugs, antiarrhythmics, certain antibiotics, mucolytics, bronchodilators, H2-receptor antagonists, cytostatics, antidepressants. These types of medicines should only be discontinued or replaced after consultation with your doctor.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

How do I prepare for the test?<\/h2>\n\t
\n\t\t
\n\t\t\t

Having an empty stomach is not required for the histamine intolerance test.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

When is the result expected?<\/h2>\n\t
\n\t\t
\n\t\t\t

On the 10th working day following the test.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>
