What is an Allergy, Aspergillus terreus Test?
The allergy, Aspergillus terreus test measures the level of specific IgE antibodies your immune system produces in response to the mould Aspergillus terreus. IgE is a type of protein the body releases when it encounters something it treats as a threat. This test is typically prescribed when a doctor suspects a mould allergy or a related lung condition. It is also referred to as the Aspergillus terreus IgE antibody test or m36 Aspergillus terreus. A small blood sample is collected from a vein in the arm.
What Does an Allergy, Aspergillus terreus Test Measure?
This is a single-parameter test. It detects and quantifies one specific marker in your blood:
| Parameter | What It Indicates |
|---|---|
| A. terreus-specific IgE | The level of IgE antibodies your immune system has produced in response to Aspergillus terreus allergens, typically encountered through inhalation |
Why is an Allergy, Aspergillus terreus Test Done?
Doctors order this test when a patient's symptoms or medical history points towards a possible allergy to Aspergillus terreus, a mould found in soil, decaying plant matter, and indoor environments.
Common Symptoms That May Require This Test
The following symptoms may prompt your doctor to recommend an allergy, Aspergillus terreus test:
- Persistent nasal blockage or a runny nose
- Frequent sneezing
- Watery, red, or itchy eyes
- Ongoing coughing or wheezing
- Itchy throat or nose
- Dry or scaly skin
- Breathlessness, especially in those with asthma or cystic fibrosis
Conditions This Test Can Help Detect
This test can assist in identifying several conditions linked to mould sensitisation:
- Allergic bronchopulmonary aspergillosis (ABPA), a lung condition caused by an immune reaction to Aspergillus moulds, commonly seen in people with asthma or cystic fibrosis
- Severe asthma with fungal sensitisation (SAFS)
- Allergic rhinitis triggered by mould exposure
- Allergic sinusitis caused by mould inhalation
Allergy, Aspergillus terreus Test for Chronic Disease Monitoring
For patients with conditions such as asthma or cystic fibrosis who have been diagnosed with ABPA, monitoring Aspergillus-specific IgE levels over time helps doctors assess how the disease is progressing and how well treatment is working. Periodic testing may form part of an ongoing management plan for these patients.
How to Prepare and What to Expect
No special preparation is needed for this test, but a few steps will help ensure an accurate result.
Do You Need to Fast?
No, fasting is not required for this test. You may eat and drink as normal before your appointment. However, if your doctor has ordered additional tests alongside this one, check whether those tests have specific fasting requirements.
Practical Tips Before Your Test
A few simple steps will help you prepare:
- Bring a detailed clinical history, including your symptoms, previous test results, and any known allergies, as this is required for the test
- Inform your doctor about all medications and supplements you are currently taking
- If you take antihistamines (medicines that block allergic reactions), discuss with your doctor whether to pause them for up to seven days before the test, as they may affect results
- Inform your doctor if you have recently had a severe allergic reaction or heavy exposure to mould
- Wear a short-sleeved or loose-sleeved top for easy access to the arm
Step-by-Step Procedure
Here is what to expect during the allergy, Aspergillus terreus test procedure:
- A trained phlebotomist (a professional who collects blood samples) will ask you to sit comfortably and extend your arm.
- A small area on your inner arm will be cleaned with an antiseptic wipe.
- A thin needle is gently inserted into a vein. You may feel a brief, mild pinch.
- A small amount of blood (approximately 3 ml) is drawn into a collection tube, and the needle is removed.
- A small bandage is placed over the site. The entire process usually takes just a few minutes.
- The sample is refrigerated and sent to the laboratory, where the serum is separated and tested using FEIA (fluorescence enzyme immunoassay) technology.
Factors That Can Affect Accuracy
Several factors may influence your test results:
- Use of antihistamines or corticosteroids before the test may lower detectable IgE levels
- Recent heavy exposure to mould spores can temporarily raise antibody levels
- Very high total serum IgE levels may cause false-positive readings
- The specific method or test kit used can affect the measurement of IgE levels
- Results must always be read alongside symptoms and clinical history
Understanding Your Allergy, Aspergillus terreus Test Results
Your results will be reported in kUA/L and assigned a class score from 0 to 6. Below is the standard reference range used to interpret findings:
| Class | A. terreus-specific IgE (kUA/L) | Interpretation |
|---|---|---|
| 0 | Less than 0.35 | Negative (no sensitisation) |
| 1 | 0.35 to 0.69 | Low positive |
| 2 | 0.70 to 3.49 | Moderate positive |
| 3 | 3.50 to 17.4 | High positive |
| 4 | 17.5 to 49.9 | Very high positive |
| 5 | 50 to 100 | Very high positive |
| 6 | Greater than 100 | Extremely high 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 alter how your results should be read:
- Patients with very high total IgE levels may show false-positive results due to non-specific binding in the test.
- Cross-reactivity between Aspergillus terreus and Aspergillus fumigatus allergens is possible due to shared molecular similarities, which may influence results in some individuals.
- A positive IgE result does not automatically confirm active allergic disease. A higher level suggests greater sensitisation, but it does not predict whether or how severely a reaction will occur.
How to Maintain Healthy Levels
While you cannot avoid mould entirely, these general steps may help reduce your exposure:
- Control indoor humidity and fix any water leaks promptly to discourage mould growth
- Use HEPA-filter air purifiers in damp or poorly ventilated areas of your home
- Avoid outdoor environments with heavy decaying vegetation, particularly during humid seasons

Frequently Asked Questions
Aspergillus terreus is a filamentous mould (a type of fungus that grows in thread-like structures) found in soil, compost, and indoor environments. It can be inhaled and, in sensitive individuals, may trigger an allergic immune response. It is considered an emerging pathogen, particularly in people with respiratory conditions.
This test is recommended for individuals with persistent respiratory symptoms such as wheezing, coughing, or breathlessness, particularly those with asthma or cystic fibrosis. People with suspected mould allergies or a history of recurrent sinus or lung issues may also benefit from this allergy, Aspergillus terreus test.
Not on its own. A positive result indicates that your immune system has produced IgE antibodies in response to A. terreus, but this does not automatically mean you will have a clinical allergic reaction. Your doctor will assess results alongside your symptoms and full medical history before drawing any conclusions.
Most people feel only a brief, mild pinch when the needle is inserted. The process is quick and straightforward. Minor bruising or slight soreness at the collection site may occur but settles on its own. Serious complications are extremely rare.
Both tests measure IgE antibodies to different species of Aspergillus mould. A. terreus and A. fumigatus are distinct species, though some cross-reactivity between their allergens is possible. Your doctor will decide which test (or combination of tests) is appropriate based on your symptoms and exposure history.
Results for the allergy, Aspergillus terreus test are typically available within three days of sample collection at Lupin Diagnostics. The report is delivered via email or WhatsApp.
