At last! An accurate and reliable test for Histamine Intolerance
Could you be low on a vital enzyme required to break down histamine in your body?
Diamine oxidase (DAO) is a gut enzyme that your body relies on to metabolise histamine. If you’re deficient in DAO, you may experience symptoms of histamine intolerance, which can affect your quality of life.
Our histamine intolerance test offers a precise, clinical way to diagnose histamine intolerance. It identifies DAO deficiencies, empowering you with the knowledge you need to guide your diet and lifestyle to avoid triggering histamine intolerance.
Histamine Intolerance Test (DAO)
✔️ Use as a standalone test for histamine intolerance or add to other IgG food intolerance tests for a complete picture
✔️ Used by GPs and clinicians in over 40 countries
✔️ Conducted in specialised certified German labs
✔️ Undertaken with medically validated ELISA test method
✔️ Tested with blood serum for accuracy (food intolerance blood test)
What is histamine?
Histamine is a natural and important compound found in the human body and in many foods. It performs many functions including regulating your:
- Sleep-wake cycle
- Body temperature
- Blood pressure
- Immune system.
Which foods are high in histamine?
High histamine foods include:
- Alcohol (esp. red wine and champagne)
- Cheese
- Seafood, fish (particularly tuna, swordfish) and fish sauces
- Raw meat sausages (e.g. salami, bacon)
- Sauerkraut
- Vegetables (e.g. tomatoes, spinach and eggplant)
- Fruits (e.g. strawberry, pineapple, banana)
- Chocolate
- Fermented foods.
Histamine intolerance
Most people are able to regulate histamine levels well because they produce the right amount of certain enzymes (including DAO), which break down excessive histamine in food and prevent it from accumulating.
However, if you don’t produce sufficient amounts of DAO and you eat a meal rich in histamine, you are likely to get an allergic type response.
Symptoms of histamine intolerance include:
- Hayfever
- Migraines
- Dizziness
- Gastrointestinal complaints
- Tachycardia (fast heart rate), arrhythmia (irregular heartbeat)
- Menstrual pain
- Asthma
- Depression
- Itching, red skin.
One simple test could identify the cause of these troubling symptoms and improve your quality of life.
Better still, if you wish to test for more potential food sensitivities or delayed IgG allergies, once you receive your results you can use the same blood sample.
With your test, you will receive:
- An analysis of your blood sample to determine whether a DAO deficiency is present; giving you an accurate measurement of your DAO level.
- If DAO deficiency is present, avoidance or limitation of histamine-rich, and histamine-releasing, foods may be recommended and possible supplementation with a DAO enzyme replacement or other vitamin supplements may also be useful (DAO enzyme and vitamin supplements not provided by ImuPro).
Frequently Asked Questions
What is Histamine and histamine intolerance?
Histamine is an important chemical which is generated in the body itself and also supplied through food. Histamine is stored in mast cells and nerve cells and is available there to be released. A problem may arise if there is an overabundance of histamine and it is unable to be broken down by means of the enzyme Diamine oxidase (DAO). If the enzyme is not available in sufficient quantity symptoms of a histamine intolerance occur.
Can I have a histamine intolerance as well as a delayed food allergy?
Yes a histamine intolerance is indicated by low DAO enzyme activity and can cause histamine related symptoms. At the same time you can have delayed IgG reactions to food. With a histamine intolerance you need to reduce the amount of histamine rich food you have in a meal. With a delayed IgG reaction you need to eliminate those foods for a period of time before gradually reintroducing them in to your diet. The ImuPro Bundle Test will combine the results of the Complete 270 foods and your DAO test results.
If my results show I am not histamine intolerant, what else could it be?
Symptons can often present the same but the causes and therefore the testing is different. If your DAO test results show normal DAO enzyme activity then it wont be the reason for your symptoms. Further diagnosis such as IgG (ImuPro Test), IgE classic allergy or other tests should be carried out to find the cause.
What foods are high in histamine?
Food items that undergo a long ageing process are particularly rich in histamine. Examples of foods rich in histamine alcoholic beverages (especially champagne, red wine and wheat beer), aged cheeses, chocolate, aged or cured meats like salami, vinegar, tomatoes, citrus fruits, strawberries, pineapple and some nuts like cashews and walnuts.
What’s the difference with the DAO (Histamine Intolerance) Test and other histamine tests?
The DAO (Histamine Intolerance) test is not measuring histamine levels. It is measuring the DAO enzyme activity in your body which is responsible for breaking down the excess histamine in food. If you do not produce enough DAO enzyme you cannot break down histamine adequately and that can lead to allergic type symptoms. We are the only company in Australia who offer this type of test direct to consumer. If the test results indicate an intolerance, you can change your diet and reduce your intake of foods containing histamine. Once you have measured your DAO level, it is not likely to change too significantly over time. This is unlike tests for histamine itself which can change dramatically depending on environment and diet. We analyse DAO activity via a blood serum sample.
Do I have to stop taking anti-histamines prior to testing?
No you dont need to stop taking anti-histamines. Just stop histamine rich food 2 days prior to blood collection: alcohol, cheese, chocolate, cured meats, fermented foods, and if applicable DAO supplements such as DAOSIN or Histame
How do I know if this test is right for me?
If you react to foods like wine, cheese or chocolate and get an allergic type reaction such as red or itchy skin, runny nose, asthmatic type conditions, sinus congestion/blocked nose or headaches then it could be because your body is not breaking down the excess histamine contained in food. Once we measure your DAO enzyme it is a good indication if your symptoms are caused by a histamine intolerance or not.
Do I have to eliminate high histamine foods from my diet?
If your test results show you have low DAO enzyme activity then you need to cut down the amount of histamine rich foods you have in a meal. (Unlike the IgG ImuPro results where you need to eliminate elevated foods for a period of time).
