Cladosporium Mold Allergy Test
This mold allergy blood test measures IgE antibodies against Cladosporium herbarum spores, a common indoor and outdoor mold that can contribute to nasal, eye, and respiratory allergy symptoms.

Quick answer
This blood test measures immunoglobulin E antibodies directed at Cladosporium herbarum, one of the most widespread mold species. It is intended for people with persistent nasal congestion, sneezing, eye irritation, or respiratory symptoms that may worsen in damp environments. A healthcare provider uses the result together with your environment and symptom pattern.
What this test measures
The Cladosporium herbarum allergy test detects allergen-specific immunoglobulin E against proteins from this mold species. Cladosporium is found indoors and outdoors and thrives in damp areas such as basements, bathrooms, and window frames. Because mold spores are small and airborne, exposure can affect the nose, eyes, and airways. The immunoassay reports a quantitative antibody level and an IgE class for the specific mold.
A blood sample is collected through a standard venipuncture and analyzed in a laboratory. The assay measures Cladosporium-specific IgE in kilounits per liter, and supporting markers such as total IgE and eosinophil counts can be included. When a broader mold panel is ordered, results for related molds such as Alternaria or Aspergillus may appear alongside Cladosporium, which helps separate cross-reactive patterns from a primary sensitization.
People seek this test when allergy symptoms persist indoors, worsen in humid weather, or appear after water damage in a home or workplace. It is also used to help refine an allergy treatment or avoidance plan. Testing confirms sensitization rather than disease, so a clinician interprets the result with your history, environment, and other findings.
- Cladosporium herbarum-specific IgE antibodies
- Quantitative sIgE concentration reported in kU/L
- Allergen-specific IgE class on the zero to six scale
- Total serum IgE
- Blood eosinophil count
- Related mold IgE markers when a broader panel is included
Why people order this test
- Investigate year-round or damp-environment allergy symptoms
- Distinguish mold sensitization from other airborne triggers
- Support an indoor mold avoidance plan
- Evaluate symptoms that worsen after water damage
- Provide objective data for an allergy management discussion
How to prepare
No fasting is required for this allergy blood test, and a single blood draw is typically sufficient. Follow the lab instructions provided with your order and report any relevant medications or health conditions to the collector.
Understanding your results
Results are generally returned within one to three business days. A positive result indicates IgE antibodies to Cladosporium herbarum, which means sensitization rather than a confirmed disease. A healthcare provider interprets the level in the context of your symptoms and exposures.

Frequently Asked Questions
Where is Cladosporium herbarum commonly found?
It is a widespread mold found indoors and outdoors, especially in damp materials, soil, plant debris, and humid indoor spaces.
Does a positive test mean I have a mold allergy?
It means antibodies to the mold were detected. A healthcare provider decides whether that sensitization explains your symptoms.
Can mold allergy symptoms look like a cold?
Yes. Sneezing, congestion, and runny nose caused by mold can resemble a cold, but allergy symptoms often persist as long as exposure continues.
Do I need to fast?
Fasting is not required for allergy blood testing unless the laboratory instructs otherwise.
Can children be tested for mold allergy?
Yes. Allergy blood testing can be performed at various ages, and a pediatric provider can determine whether testing is appropriate.
