Understanding Lab Tests for Aspergillosis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Aspergillosis is a group of diseases caused by infection or allergic reaction to Aspergillus fungus, commonly Aspergillus fumigatus. These conditions can range from mild allergic reactions to serious lung infections. Blood tests play a crucial role in diagnosing aspergillosis by detecting immune responses to the fungus.
Top Recommended Test
Respiratory Allergy Panel Region III: GA, northern FL, SC
This regional panel tests for allergic reactions to Aspergillus fumigatus spores commonly found in the southeastern United States. It helps diagnose aspergillosis by detecting specific antibodies produced in response to inhalation of these fungal spores, which can cause diseases ranging from mild allergic reactions to serious lung infections.

How Blood Testing Helps Diagnose Aspergillosis
When the immune system encounters Aspergillus spores, it produces specific antibodies as a defense mechanism. Respiratory allergy panels can detect these antibodies in the blood, helping to confirm whether aspergillosis is caused by an allergic reaction to the fungus. This testing is particularly important because symptoms can vary widely and may overlap with other respiratory conditions.
Other Relevant Tests
Respiratory Allergy Panel Region IV: FL, south of Orlando
Designed for the southern Florida region, this panel identifies allergic responses to molds including Aspergillus that can cause aspergillosis. The test detects immune reactions that result in lung problems and allergic symptoms specific to fungal exposures common in this geographic area.

Respiratory Allergy Profile Region VI: AL, AR, LA, MS
This panel screens for allergic reactions to Aspergillus fumigatus prevalent in the Gulf Coast states. It helps diagnose the variety of lung diseases collectively known as aspergillosis by measuring the body's immune response to this common environmental fungus.

Respiratory Allergy Profile Region XVII: CA (northwest), OR (west), WA (west)
Tailored for the Pacific Northwest region, this comprehensive panel detects allergic reactions to Aspergillus fumigatus found in this climate. It identifies immune responses that indicate aspergillosis, helping diagnose conditions that can cause symptoms ranging from mild wheezing to severe shortness of breath.

Understanding Regional Testing
Different geographic regions have varying concentrations and types of Aspergillus species due to climate and environmental factors. Regional respiratory allergy panels are specifically designed to test for the most common fungal allergens in your area, providing more accurate and relevant results for diagnosing aspergillosis based on your location.
