What is this test?

The Aspergillus amstelodami IgE antibody test is a laboratory test that measures the level of immunoglobulin E (IgE) antibodies specifically directed against Aspergillus amstelodami, a species of mold (fungus) commonly found in indoor and outdoor environments. When your immune system detects this mold as a threat, it produces IgE antibodies, which can trigger allergic symptoms.

How is the test performed?

A healthcare professional will collect a blood sample from a vein in your arm. The sample is then sent to a laboratory where it is analyzed to detect and measure the concentration of specific IgE antibodies against Aspergillus amstelodami. The results are typically reported in kilounits per liter (kU/L) or as a class level (0-6) indicating the intensity of the allergic response.

Why might I need this test?

Your doctor may order this test if you have symptoms suggestive of a mold allergy, such as sneezing, nasal congestion, wheezing, skin rash, or respiratory problems. It is particularly useful in diagnosing allergic bronchopulmonary aspergillosis (ABPA), a condition seen in patients with asthma or cystic fibrosis where the immune system overreacts to Aspergillus mold in the lungs.

What do the results mean?

Results are interpreted along with your clinical symptoms and other test results. A positive result indicates that you have developed IgE antibodies to Aspergillus amstelodami, suggesting sensitization to this mold. However, being sensitized does not always mean you will experience symptoms. Your doctor will correlate the test results with your medical history and physical examination to determine if treatment is necessary.

Reference range

Negative: < 0.35 kU/L; Class I (Low): 0.35-0.69 kU/L; Class II (Moderate): 0.70-3.49 kU/L; Class III (High): 3.50-17.49 kU/L; Class IV (Very High): 17.50-49.99 kU/L; Class V (Very High): 50.00-99.99 kU/L; Class VI (Extremely High): >= 100 kU/LN/A

Specimen: serum

No special preparation required. Patient does not need to fast. Inform laboratory of current medications, particularly antihistamines or corticosteroids, which may affect results.

Clinical interpretation

Frequently asked questions

Do I need to fast before this test?
No, fasting is not required for this blood test. You can eat and drink normally before the test.
Are there any risks associated with this test?
The risks are minimal and similar to any routine blood draw, including slight bruising, bleeding, or infection at the puncture site.
How long does it take to get results?
Results are typically available within a few days to a week, depending on the laboratory.
Can this test diagnose if I'm currently having an allergic reaction?
This test detects IgE antibodies, which indicate sensitization (prior exposure and immune response). It does not directly measure if you are currently experiencing symptoms. Your doctor will interpret results in the context of your current health status.
What happens if my result is positive?
A positive result means you have IgE antibodies to Aspergillus amstelodami. Your doctor will discuss treatment options, which may include antihistamines, nasal corticosteroids, bronchodilators, or avoidance strategies. In some cases, allergy shots (immunotherapy) may be recommended.
