In short
This article discusses clinical trials involving the use of Aspergillus Fumigatus, a type of mold, in allergy testing. While the main focus of the trial is on house dust mite allergies, Aspergillus Fumigatus is mentioned as part of a skin prick test solution. This information is valuable for patients interested in understanding allergy testing procedures and the various allergens involved in such tests.

What is Aspergillus Fumigatus?
Aspergillus fumigatus is a type of mold fungus that is commonly found in the environment. In the context of medical treatment, it is used as an allergen extract for diagnostic purposes. This substance is specifically used in allergy testing to identify if a person is allergic to this particular type of mold.
Medical Uses
The primary medical use of Aspergillus fumigatus in the context provided is for diagnostic purposes, specifically in allergy testing. It is used in a procedure called a skin prick test, which helps doctors determine if a patient is allergic to this specific type of mold.
Aspergillus fumigatus is classified under the ATC code V01AA04, which stands for "Mould fungus and yeast fungus" in the context of allergen extracts for diagnostic use. This classification indicates that it's used primarily for identifying allergies related to mold and yeast fungi.
Administration Method
The Aspergillus fumigatus allergen extract is administered via a skin prick test. This test involves applying a small amount of the allergen solution to the skin, usually on the forearm or back, and then lightly pricking or scratching the skin to allow the solution to enter just below the surface.
The solution is typically provided in a dropper bottle, with the dosage usually being one drop per test. The maximum daily dose and total dose are both listed as 1 drop (Gtt).
Allergic Reactions and Testing
If a person is allergic to Aspergillus fumigatus, they may develop a small, itchy bump or wheal at the site of the skin prick test within about 15-20 minutes. The size of this reaction helps doctors determine the severity of the allergy.
It's important to note that Aspergillus fumigatus is just one of many allergens that might be tested during a comprehensive allergy screening. Other common allergens tested may include:
- House dust mites (Dermatophagoides pteronyssinus and Dermatophagoides farinae)
- Animal dander (like cat and dog epithelia)
- Grass and tree pollens
Safety Considerations
While skin prick tests are generally safe, they should always be performed under medical supervision. This is because there's a small risk of a more severe allergic reaction. Healthcare providers will have emergency medications on hand just in case.
It's crucial for patients to inform their healthcare provider about all medications they're taking before the test, as some medications can interfere with the results. Additionally, patients with certain skin conditions or who are pregnant may need to postpone the test or consider alternative allergy testing methods.
