What is the purpose of this test?
Order this Aspergillus Fumigatus Allergy Blood Test measures the IgE antibody levels in the blood to detect an allergy to aspergillus fumigatus. Aspergillus fumigatus is one of the most prevalent airborne fungi, abundant throughout the environment, and can flourish indoors and outdoors. Therefore, most individuals are likely to inhale aspergillus spores regularly. Allergies to this mold are uncommon; however, some individuals may experience a severe allergic reaction from contact with aspergillus spores. Exposure to Aspergillus fumigatus spores can cause aspergillosis, an allergic reaction and one of the most common infections caused by this fungus species. Although individuals with a strong immune system typically do not experience harmful symptoms, individuals with a weakened immune system may face severe reactions—especially those with respiratory problems, cystic fibrosis, or asthma.

An allergic reaction to Aspergillus fumigatus is triggered by an individual's immune system response. For example, the body views certain substances pathogens (spores) as toxic and produces IgE antibodies to combat these contaminants. Unfortunately, these antibodies cause the release of the chemical histamine, which prompts the symptoms of an allergic reaction.
