Understanding Lab Tests for Fungal Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Fungal allergies are immune system reactions to molds and fungi commonly found in indoor and outdoor environments. These microscopic organisms can trigger symptoms like sneezing, coughing, difficulty breathing, skin rash, and itching. Blood tests are the primary method for accurately identifying specific fungal allergens responsible for your symptoms.

How Blood Tests Diagnose Fungal Allergies
Blood tests for fungal allergies measure specific IgE antibodies that your immune system produces in response to particular mold and fungal proteins. When these antibody levels are elevated, it indicates an allergic sensitivity to those specific fungi. This precise identification is crucial for developing an effective treatment plan and avoiding trigger allergens.
Other Relevant Tests by Region
Respiratory Allergy Profile Region IX: KS, NE, ND, SD
Designed for the Great Plains region, this test screens for allergies to Alternaria alternata, Aspergillus fumigatus, and Cladosporium herbarum - common molds in this geographic area. High antibody levels to these biomarkers indicate specific fungal allergies that may be causing your respiratory and other allergic symptoms.
