Quick answer
The Phoma Betae Allergy Test is a blood test that checks for IgE antibodies against Phoma betae, a mold found in soil and on plants. Because it grows on plant material, exposure can occur during gardening, farming, or time in areas with abundant vegetation. Sensitized people may notice nasal, eye, or respiratory symptoms after exposure. The test helps show whether the immune system has become sensitized to this mold.
What this test measures
Phoma betae is a fungal species commonly associated with soil and with plant debris, including weak or damaged plants. Like other molds, it releases spores and fragments that can become airborne and be inhaled. When a person is sensitized, the immune system produces IgE antibodies against mold proteins, and a blood test can measure the concentration of Phoma betae-specific IgE.
The test uses a routine blood sample, and results are usually reported as a quantitative value in kilounits per liter along with a graded class. Mold panels often include several species because sensitization to multiple molds is common, and total serum IgE may be added when an expanded panel is ordered. The result reflects sensitization rather than infection.
People who develop allergy symptoms around soil, compost, or plant material may order this test, and it can be included in a broader mold or outdoor allergen panel. It is helpful when other common molds have been tested but symptoms continue. A qualified healthcare provider should interpret the result with the person's exposure history and clinical picture.
- Phoma betae-specific IgE antibodies
- Quantitative allergen-specific IgE in kU/L
- Allergen-specific IgE class on a graded scale
- Total serum IgE when included
- Other mold extract markers when a mold panel is ordered
- Serum eosinophil count when included in the order
Why people order this test
- Investigate allergy symptoms linked to soil or plant material exposure
- Assess sensitization to an uncommon mold when common molds are negative
- Add detail to a broader mold or outdoor allergen panel
- Follow up on a positive mold screening result
- Support discussions about gardening and outdoor exposure habits
How to prepare
No fasting is required. A blood sample is collected at the lab, and normal eating and drinking beforehand are acceptable. Follow the lab's instructions if other tests are included.
Understanding your results
Results are generally available within one to three business days. A positive result suggests sensitization to Phoma betae, while a negative result makes that sensitivity less likely. A healthcare provider should interpret the finding with your symptoms and exposure history.

Frequently Asked Questions
Where is Phoma betae found?
It is a soil fungus often associated with plants and plant debris. Exposure can occur through gardening, farming, or handling compost and vegetation.
Does this test detect a mold infection?
No. It measures allergic sensitization through IgE antibodies. Infection testing looks for the organism itself and is ordered separately when needed.
Why test for an uncommon mold?
When common mold tests are negative but symptoms persist around soil or plants, a less common mold such as Phoma betae can be relevant.
Can mold sensitization cause breathing symptoms?
Mold sensitization is associated with nasal and respiratory symptoms and can contribute to asthma in some people. A healthcare provider can assess your individual situation.
How is the sample collected?
A small blood sample is drawn from a vein, usually in the arm, during a short lab visit.
