Understanding Lab Tests for Fungal Allergies
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Fungal allergies occur when the immune system overreacts to airborne mold spores and other fungal particles. These allergies can cause respiratory symptoms such as coughing, wheezing, nasal congestion, and sneezing. Blood tests that measure specific antibodies are the primary method for identifying which fungi trigger allergic reactions.
Recommended Test
Respiratory Allergy Profile Region XV: ID (south), NV
This comprehensive respiratory allergy panel tests for multiple common mold allergens including Aspergillus fumigatus, Cladosporium herbarum, and Penicillium notatum. These molds are frequent causes of allergic reactions that lead to respiratory symptoms like coughing, wheezing, and nasal congestion. The test identifies specific fungal sensitivities to help guide treatment and environmental control measures.

How Blood Tests Diagnose Fungal Allergies
When exposed to fungal allergens, the immune system produces specific antibodies called immunoglobulin E (IgE). Blood tests can measure these IgE antibodies to determine exactly which molds and fungi are causing allergic reactions, enabling targeted treatment and avoidance strategies.
Common Fungal Allergens Tested
The respiratory allergy profile includes testing for several important mold allergens. Aspergillus fumigatus is commonly found in soil and decaying vegetation. Cladosporium herbarum is one of the most widespread outdoor molds, often found on plants and in soil. Penicillium notatum can be found both indoors and outdoors, particularly in damp environments. Each of these molds can trigger similar respiratory allergic symptoms in sensitive individuals.
