Have you ever felt symptoms similar to an allergic reaction after eating certain foods? Do you often feel headaches, stomach problems and itching for no apparent reason? You may suffer from histamine intolerance. Histamine intolerance is a hypersensitivity to histamine, a natural substance in the body that helps the immune system fight pathogens and toxins. Symptoms of histamine intolerance can be similar to those of an allergic reaction and include headache, migraine, dizziness, itching, swelling, cramps, diarrhea, cough, asthma, runny nose and palpitations.
Our histamine intolerance test is a test that measures the level of the enzyme diamine oxidase (DAO) in the blood, which is necessary to break down histamine in food. By detecting your DAO level, we can determine whether you suffer from histamine intolerance or not.
The histamine intolerance test is particularly useful for people suffering from migraines, IBS, fibromyalgia and chronic fatigue, as these conditions are often associated with histamine intolerance. By finding out if you suffer from histamine intolerance, you can take the right steps to avoid foods rich in histamine and thereby reduce your symptoms.
If you suffer from histamine intolerance, it is important to avoid foods rich in histamine, such as red wine, tuna, sardines, cheeses, sausages and cold cuts, and certain fruits and vegetables. You can also take an enzyme containing diamine oxidase to break down histamine in food.
Let us help you find peace in your body again. Order your histamine intolerance test today and take the first step towards living a healthier and more comfortable life.
Reference Range for S-Diamine Oxidase
- > 10 U/mL: Normal amount of DAO
- 3 – 10 U/mL: Reduced amount of DAO
- Strongly reduced amount of DAO
What does a low value of DAO mean?
If the body has too little DAO or if the enzyme does not work properly, histamine can accumulate in the body. This can lead to symptoms similar to allergic reactions, such as itching, nasal congestion or stomach upset.
Accredited analysis of DAO
The DAO analysis is carried out in an accredited laboratory, which means that the analysis meets high quality and reliability requirements. It is important to know that measuring the DAO level is not suitable in acute allergic reactions (anaphylaxis) or during pregnancy, as the results may be affected.
Factors that can decrease the activity of the enzyme include certain medications, such as antibiotics, morphine, antacids, and blood pressure medications. In addition, certain diseases can affect DAO activity. For example, tumors, cystic fibrosis and kidney failure can sometimes increase enzyme activity, while conditions such as allergies and inflammatory bowel disease (IBD) often decrease it.
