What is this test?

The Aspergillus amstelodami antibody test is a blood test that looks for specific antibodies (IgG) your body produces in response to Aspergillus amstelodami, a common type of mold found in the environment. This fungus is often present in soil, decaying vegetation, and indoor environments with moisture.

Why do I need this test?

Your doctor may order this test if you have symptoms of a fungal infection or allergic reaction to Aspergillus mold, such as persistent cough, wheezing, fever, or breathing difficulties. It is particularly useful in diagnosing conditions like allergic bronchopulmonary aspergillosis (ABPA), aspergilloma (fungus ball), or invasive aspergillosis, especially in people with asthma, cystic fibrosis, or weakened immune systems.

How is the test performed?

A healthcare professional will draw a small blood sample from a vein in your arm. The sample is then sent to a laboratory where it is tested for the presence of IgG antibodies against Aspergillus amstelodami. No special preparation, such as fasting, is typically required.

What do the results mean?

Results are typically reported as positive (antibodies detected) or negative (no antibodies detected). A positive result indicates that you have been exposed to Aspergillus amstelodami and your immune system has produced antibodies. Your doctor will interpret these results along with your symptoms, medical history, and other test results to make a diagnosis.

Reference range

Negative: < 1:2 titer or < 20 Units/mL; Equivocal: 1:2 to 1:4 titer or 20-40 Units/mL; Positive: ≥ 1:4 titer or ≥ 40 Units/mLN/A

Specimen: serum

No special preparation required. This test does not require fasting. Inform the laboratory of any recent antifungal therapy or immunosuppressed status.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Is there any preparation needed before the test?
No special preparation is usually required. You can eat and drink normally before the test. However, always follow any specific instructions provided by your healthcare provider.
Does a positive result mean I have an active infection?
Not necessarily. A positive result indicates that you have been exposed to Aspergillus amstelodami and have developed antibodies. Your doctor will consider your symptoms, other test results (such as IgE levels or chest imaging), and medical history to determine if you have an active infection or an allergic reaction.
Can this test detect all types of Aspergillus infections?
No, this test specifically detects antibodies to Aspergillus amstelodami. Other Aspergillus species may cause similar infections, so your doctor may order additional tests if a different species is suspected.
Is the test safe?
Yes, the test is very safe. It involves a routine blood draw, which may cause minor bruising or soreness at the injection site. There are no significant risks associated with this test.
How long does it take to get results?
Results are typically available within a few days to a week, depending on the laboratory. Your healthcare provider will inform you when the results are ready.
