Aspergillus-Fumigatus (IgE) is a blood test that measures allergen-specific IgE antibodies against Aspergillus fumigatus, a common environmental fungus. The test is needed to identify sensitisation or an allergic response to this fungus and may support the evaluation of conditions such as allergic asthma or allergic bronchopulmonary aspergillosis (ABPA). Results are interpreted along with symptoms, clinical history, and other allergy or respiratory investigations.
Aspergillus fumigatus is a type of fungus commonly found in soil, dust, compost, and decaying organic material. Its airborne spores can be inhaled.
A positive result indicates that the immune system has produced IgE antibodies against Aspergillus fumigatus, suggesting sensitisation to the fungus.
No. A positive specific-IgE result indicates allergic sensitisation, not necessarily a fungal infection.
Yes. It can support the evaluation of allergic bronchopulmonary aspergillosis (ABPA), but diagnosis requires consideration of other findings such as total IgE, clinical symptoms, eosinophils, and chest imaging.
ABPA is an exaggerated immune response to Aspergillus in the airways. It occurs most often in people with asthma or cystic fibrosis.
