Aureobasidium Pullulans Sensitivity Test
An Aureobasidium pullulans allergy blood test measures IgE antibodies against a mold that grows on damp surfaces and plant material. It helps assess sensitization when nasal, eye, or breathing symptoms persist in damp settings.

Quick answer
The Aureobasidium pullulans allergy test uses a blood sample to measure immunoglobulin E antibodies against this mold, a dark yeast-like fungus often found on damp surfaces, painted wood, and plant leaves. It is commonly grouped with other mold tests when someone has chronic allergy symptoms that may be linked to moisture. The result shows sensitization and is read with the person's history.
What this test measures
Aureobasidium pullulans is a widespread fungus that can appear as dark spots on damp walls, window frames, and outdoor surfaces. It also grows on plant leaves and in soil. When contaminated materials are disturbed, spores and fragments can become airborne and may trigger sneezing, congestion, itchy eyes, or wheezing in sensitive people.
The test measures allergen-specific IgE in serum with a laboratory immunoassay. The report gives a quantitative level and a reactivity class for Aureobasidium pullulans. Since molds share many allergens, clinicians often review this result with other mold and dust mite tests to build a clearer picture of what may be driving symptoms.
A positive result shows the immune system recognizes the mold; it does not prove that the mold is causing current symptoms. Exposure level, individual sensitivity, and other triggers all matter. A qualified healthcare provider interprets the finding alongside symptoms and may recommend further evaluation.

- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for Aureobasidium pullulans
- Cross-reactive fungal allergens
- Related mold spore allergens in the panel
Why people order this test
- Investigate chronic nasal or respiratory symptoms in damp buildings
- Assess mold sensitization as part of a wider allergy workup
- Review symptoms that worsen around moisture-damaged surfaces
- Compare reactivity across multiple mold species
- Support evaluation of environmental or occupational exposure
- Provide context before discussing home or workplace changes with a provider
How to prepare
No fasting is required for this test. A blood sample is collected from a vein, typically at the arm. Follow any instructions from the laboratory, particularly if the test is part of a larger mold panel.
Understanding your results
Results are usually reported within one to three business days. The report lists the specific IgE level and a reactivity class for Aureobasidium pullulans. An elevated value indicates sensitization, and a healthcare provider can explain what it means in context.

Frequently Asked Questions
What is Aureobasidium pullulans?
It is a fungus that grows on damp surfaces, painted wood, and plant material. It can release spores that trigger allergic responses in sensitive people.
How is the sample collected?
A small blood sample is drawn from a vein. The serum is then tested for IgE antibodies that react to the mold.
Does a positive result confirm a mold allergy?
It indicates sensitization. Whether symptoms are caused by the mold depends on exposure and clinical history, which a healthcare provider evaluates.
Is fasting needed before this test?
No fasting is typically required unless the test is combined with another panel that calls for it.
Can this be tested with other molds at the same time?
Yes. It is often included in a mold panel so that reactivity across several species can be compared from one blood draw.
