What Is an Allergy, Mushroom (champignon) Test?
The Allergy, Mushroom Test is a blood test that detects specific IgE (Immunoglobulin E) antibodies directed against proteins found in champignon mushrooms, also called button mushrooms or white mushrooms. When someone is allergic to mushrooms, their immune system produces these antibodies in response to mushroom proteins. The test helps doctors determine whether mushroom exposure is the cause of allergy symptoms. It is also known as the Champignon Allergy Test, the Button Mushroom Allergy Test, or the Agaricus bisporus IgE test.
What Does an Allergy, Mushroom (champignon) Test Measure?
This test measures one key marker in your blood. The table below explains what it looks for and why it matters.
| Parameter | What It Measures |
|---|---|
| Mushroom-specific IgE antibodies | The level of IgE antibodies your immune system has produced in response to champignon mushroom proteins. A raised level suggests sensitisation to mushroom allergens. |
Why Is an Allergy, Mushroom (champignon) Test Done?
Doctors may order this Allergy, Mushroom Test when a patient reports symptoms after eating or handling mushrooms. It can also help identify cross-reactive sensitivities in people already known to have mould allergies.
Common Symptoms That May Require This Test
The following symptoms, especially if they appear after mushroom consumption, are common reasons a doctor may request this test:
- Hives (itchy raised bumps on the skin) or skin rash
- Swelling of the lips, face, or tongue
- Abdominal pain, nausea, or vomiting
- Nasal congestion or sneezing
- Breathing difficulties
- Anaphylaxis (a sudden, severe allergic reaction with a drop in blood pressure and difficulty breathing)
Conditions This Test Can Help Detect
This test can support the identification of the following conditions:
- Mushroom allergy presenting with skin, digestive, or respiratory symptoms
- Oral allergy syndrome triggered by raw mushrooms in people with mould-related allergic rhinitis (hay fever)
- Cross-reactive sensitivity between mushroom proteins and common airborne moulds such as Alternaria, Cladosporium, and Aspergillus
How to Prepare and What to Expect
Preparing for this test is straightforward. No major changes to your routine are needed.
Do You Need to Fast?
No, fasting is not required before this test. You may eat and drink normally on the day of sample collection. If other tests are being done at the same time, check with your doctor whether those require fasting.
Practical Tips Before Your Test
Keep the following points in mind before going for your Allergy, Mushroom Test:
- Bring a detailed clinical history including your symptoms, previous test results, and any relevant medical records, as this is required for the test
- Wear clothing with easy access to your arm for the blood draw
- Stay well hydrated before the appointment
- Inform the phlebotomist about any medications or supplements you are currently taking
- Continue antihistamines as prescribed; they do not affect the accuracy of this blood test
- If you have kept a food diary or symptom record, bring it along
Step-by-Step Procedure
- A trained phlebotomist cleans a small area of your arm with an antiseptic solution.
- A fine needle is inserted into a vein, usually in the inner elbow. You may feel a brief sting.
- A small blood sample (approximately 3 ml) is collected into a yellow SST gel tube.
- The needle is removed, and the site is covered with a small bandage.
- In the laboratory, the sample is centrifuged to separate the serum, which is then tested using Fluorescence Enzyme Immunoassay (FEIA) technology.
- The sample is stored under refrigeration until processing, and your report is typically ready within 3 days.
Factors That Can Affect Accuracy
- Very high total IgE levels (above 1,000 kU/L), which can occasionally cause a false positive result
- Improper sample handling or storage after collection
- Cross-reactivity with other moulds or fungi
- Current medications (always inform your doctor)
Understanding Your Allergy, Mushroom (champignon) Test Results
Your results are reported as a class and a specific IgE level in kU/L. The table below outlines what each level means:
| Class | Specific IgE Level (kU/L) | Interpretation |
|---|---|---|
| 0 | Less than 0.35 | Negative / Undetectable — mushroom allergy unlikely |
| 1 | 0.35 to 0.69 | Low level — weak positive |
| 2 | 0.70 to 3.49 | Moderate level — positive |
| 3 | 3.50 to 17.49 | High level — positive |
| 4 | 17.50 to 49.99 | Very high level — strong positive |
| 5 | 50 to 100 | Very high level — strong positive |
| 6 | Greater than 100 | Very high level — strong positive |
Disclaimer: These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how results should be read:
- Patients with very high total IgE levels (above 1,000 kU/L) may receive a false positive low-level result; these should be interpreted with caution by your doctor.
- Some people react to raw mushrooms but tolerate cooked ones, because the proteins responsible may be heat-sensitive, a pattern similar to pollen food allergy syndrome.
- Patients with existing mould allergies may show a positive result due to cross-reactivity rather than a direct mushroom allergy.
How to Maintain Healthy Levels
If you are found to be allergic to mushrooms, the following general steps may help you manage your condition:
- Avoid all types of mushrooms, including shiitake, portobello, white button, and oyster varieties
- Read food labels carefully and ask about ingredients when eating at restaurants
- Discuss with your doctor whether carrying an emergency epinephrine auto-injector is appropriate for your situation

Frequently Asked Questions
The Champignon Allergy Test is a blood test that measures specific IgE antibodies against proteins in the champignon (button) mushroom. It helps determine whether your immune system is sensitised to mushroom allergens. It is useful when symptoms appear after eating or handling mushrooms.
This test is recommended for anyone who experiences repeated allergic symptoms after eating or being around mushrooms. It is also worth considering if your doctor has suggested allergy evaluation or if you work in an environment with regular mushroom exposure, such as a restaurant or farm.
A positive result means your body produces IgE antibodies against mushroom proteins, which indicates sensitisation. However, sensitisation does not always mean you will have an allergic reaction. Your doctor will consider your results alongside your symptoms and medical history to reach a conclusion.
Yes, it can. Some people eat mushrooms for years without any reaction and then develop an allergy later. If you notice new symptoms after eating mushrooms, it is worth discussing this with your doctor and getting tested.
Yes. Research shows that proteins in champignon mushrooms can cross-react with common airborne moulds such as Alternaria and Cladosporium. This means people who are allergic to moulds may also show a positive result on a mushroom IgE test due to this overlap, not necessarily because of a direct mushroom allergy.
In most cases, no. Antihistamines do not interfere with this blood test, unlike skin-prick tests. However, always inform your doctor about any medications or supplements you are taking before the test, so they can advise accordingly.
Reports for the Allergy, Mushroom Test at Lupin Diagnostics are typically available within 3 days of sample collection. You will receive your digital report via email or WhatsApp.
