Diamine Oxidase Activity

Diamine Oxidase Activity

The Diamine Oxidase (DAO) activity test is a diagnostic procedure designed to assess the level of the DAO enzyme in the blood, crucial for breaking down histamine. Histamine, a compound naturally produced by the body and present in certain foods, can cause adverse effects if not properly metabolized. The test primarily aids in diagnosing histamine intolerance, a condition where there's an imbalance between histamine intake and the body's ability to degrade it, leading to symptoms like headaches, nausea, and gastrointestinal issues. Conducted via a simple blood draw, the test measures DAO activity in histamine-degrading units (HDU), with normal levels above 80 HDU/mL. Factors such as genetics, medications, and lifestyle choices can influence DAO activity. Treatment often involves dietary modifications to reduce histamine intake. The DAO activity test, sometimes complemented by genetic testing, is essential for identifying histamine metabolism disorders, helping improve patient quality of life through targeted management strategies.

Purpose of the test

The DAO activity test is essential for diagnosing histamine intolerance by measuring the DAO enzyme in the blood. This enzyme is vital for breaking down histamine, which, if not managed, can cause adverse effects. The test helps identify if symptoms like headaches, nausea, and gastrointestinal issues are due to DAO deficiency. Key points include:

- Test Purpose: Diagnose histamine intolerance.
- Symptoms: Headaches, gastrointestinal disorders, skin issues.
- Factors Affecting DAO: Medications, alcohol, inflammatory diseases.
- Dietary Considerations: Avoid high-histamine foods like citrus, seafood, and chocolate.
- Management: Dietary changes and lifestyle modifications.

Who Should Get Tested

The Diamine Oxidase (DAO) activity test is essential for diagnosing histamine intolerance, a condition where the body struggles to break down histamine. This can lead to symptoms like headaches, nausea, and skin issues. The test involves a simple blood draw to measure DAO enzyme levels, with results indicating potential deficiencies. Key symptoms of DAO deficiency include:

- Headaches and migraines
- Gastrointestinal disorders
- Skin issues
- Muscular and skeletal problems

Dietary changes, such as avoiding high-histamine foods like citrus fruits and seafood, are crucial for managing symptoms.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results is crucial for managing histamine intolerance. The DAO activity test measures the enzyme's level in the blood, essential for histamine degradation. Key points include:

- Normal Levels: Above 80 HDU/mL indicates sufficient DAO activity.
- Low Levels: Suggest a deficiency, potentially causing symptoms like headaches and gastrointestinal issues.
- Influencing Factors: Medications, alcohol, and certain diseases can affect DAO activity.
- Dietary Impact: Foods high in histamine, like citrus and seafood, may worsen symptoms.
- Management: Dietary changes and lifestyle adjustments can help improve symptoms and DAO activity.
