What this test measures
The Mold Allergy Panel measures specific immunoglobulin E (IgE) antibodies to five common environmental molds: Aspergillus, Cladosporium, Penicillium, Alternaria, and Stachybotrys. These antibodies are part of the immune system's response to allergens like mold spores. When individuals sensitive to mold are exposed to these fungi, their immune system produces IgE antibodies, which can trigger allergic symptoms.
These molds are commonly found in homes, workplaces, and outdoor environments. Some grow in damp areas like basements or bathrooms, while others are found in soil, plants, or decaying leaves. While there are 100,000 different types of molds, not all cause allergy symptoms. Some of the most common molds that result in allergies include alternaria, aspergillus, cladosporium, and penicillium. This panel tests for the most clinically relevant mold allergens that may cause respiratory and other allergic reactions in sensitive individuals.
What's included
Who should consider this test
You might consider this test if you are experiencing any of the following:
- Individuals experiencing unexplained respiratory symptoms such as sneezing, runny nose, nasal congestion, or coughing that worsen in certain environments or during specific seasons.
- Those living or working in buildings with water damage, high humidity, poor ventilation, or visible mold growth who want to determine if their symptoms are allergy-related.
- People with asthma that seems to worsen in damp environments or during certain weather conditions, as mold allergies can trigger asthma attacks.
- Individuals with chronic sinus problems, itchy or watery eyes, or skin irritation that may be related to environmental exposures.
- Those considering purchasing or renting homes in areas prone to moisture issues who want to assess their potential sensitivity to common indoor molds before making decisions about their living environment.
What to expect
Preparation
No fasting required. Individuals may continue taking medications as usual, as antihistamines and other allergy medications do not affect blood-based IgE testing.
Sample Type
A simple blood draw from a vein in the arm, typically taking just a few minutes. The sample will be sent to the laboratory for analysis of specific IgE antibodies.
Collection
After checking in at the lab location, a trained phlebotomist will collect the blood sample. The entire visit typically takes 10-15 minutes, with no doctor visit required.
Turnaround
Results are typically available within 1-3 business days and will be securely delivered through an online patient portal.
Understanding your results
Reference values apply to all ages. Concentrations of 0.70 kU/L or more (class 2 and above) will flag as abnormally high. Results are typically reported as specific IgE levels for each of the five mold allergens tested, along with an interpretation of whether levels indicate potential sensitivity.
| Population | Reference Range | Notes |
|---|---|---|
| Adults | < 0.35 kU/L (Class 0-1) | Normal or low levels, indicating minimal sensitivity to the specific mold |
| Adults | 0.35-0.70 kU/L (Class 1) | Borderline sensitivity that may or may not cause symptoms |
| Adults | > 0.70 kU/L (Class 2+) | Elevated levels indicating potential allergic sensitivity to the specific mold |
Reference ranges may vary by laboratory and individual factors. Results should be interpreted by a healthcare provider in the context of your overall health.
What does a “Low” result mean?
Negative results may rule out allergy, except in rare cases of allergic disease induced by exposure to a single allergen. Normal or low IgE levels typically indicate that the tested molds are unlikely to be triggering current allergic symptoms. However, this does not rule out sensitivity to other environmental allergens not included in this panel, nor does it exclude the possibility of developing sensitivities in the future. It's uncommon for a blood test to show that you don't have an allergy when you actually do (also known as a false negative).
What does a “High” result mean?
Positive results indicate the possibility of allergic disease induced by one or more allergens present in the panel. Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum, and test results must be interpreted in the clinical context. Elevated IgE levels to specific molds may indicate that exposure to those particular fungi could trigger allergic symptoms such as respiratory irritation, nasal congestion, or asthma exacerbations. However, having detectable IgE antibodies does not guarantee that symptoms will occur with every exposure, as symptom severity can vary based on exposure levels and individual sensitivity.
Privacy & confidentiality
All test results are strictly confidential and protected under HIPAA regulations. Results are not shared with insurance companies or added to medical records unless you choose to share them with your healthcare provider. No insurance billing means complete privacy for your health information.
