Understanding Lab Tests for Penicillium Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Penicillium is a common type of mold found both indoors and outdoors that can trigger allergic reactions in sensitive individuals. Symptoms may include sneezing, runny nose, itchy eyes, coughing, and in some cases, asthma-like symptoms. A specific blood test can accurately identify if you have an allergy to Penicillium mold.
Recommended Test
Respiratory Allergy Profile Region IX: KS, NE, ND, SD
This comprehensive respiratory allergy panel includes testing for Penicillium notatum, a common mold species that frequently causes allergic reactions. The test measures specific IgE antibodies in your blood, and elevated levels indicate an allergic sensitivity to this mold. This regional profile is specifically designed to test for allergens commonly found in Kansas, Nebraska, North Dakota, and South Dakota.

Diagnosing Penicillium Allergy
Since mold allergy symptoms can overlap with other respiratory conditions and environmental allergies, definitive diagnosis requires testing that measures your immune system's specific response to Penicillium. Blood tests detect allergen-specific IgE antibodies, which are produced when your body mistakenly identifies harmless mold spores as threats.
Understanding Your Results
The test measures the concentration of IgE antibodies specific to Penicillium in your blood. Higher levels typically correlate with greater allergic sensitivity and may help explain symptoms you experience when exposed to moldy environments. Results can guide your healthcare provider in developing an appropriate treatment plan, which may include avoidance strategies, medications, or immunotherapy.
Important Considerations
