What is this test?

The Aspergillus amstelodami IgG antibody test is a blood test that measures whether your immune system has produced IgG antibodies against Aspergillus amstelodami, a common mold found in the environment. This fungus is part of the Aspergillus family, which includes many different species that can cause allergic reactions and infections in humans.

Why do I need this test?

Your doctor may order this test if you have symptoms of an Aspergillus-related condition, such as: chronic cough, wheezing, shortness of breath, fever, or sinus problems. It is commonly used to help diagnose allergic bronchopulmonary aspergillosis (ABPA), a condition where the immune system overreacts to Aspergillus mold in the lungs. It may also be used to monitor treatment response in patients with known fungal infections.

How is the test performed?

A healthcare professional will draw a small blood sample from a vein in your arm. The blood sample is then sent to a laboratory where it is tested for the presence of IgG antibodies against Aspergillus amstelodami. The test typically does not require any special preparation, such as fasting.

Understanding your results

Results are usually reported as positive or negative. A positive result indicates that IgG antibodies against Aspergillus amstelodami were detected in your blood, suggesting past or current exposure to this fungus. A negative result means no antibodies were detected. Your doctor will interpret these results together with your symptoms, medical history, and other test results to make a diagnosis.

Are there any risks?

The risks associated with this test are minimal and similar to those of any routine blood test. You may experience slight pain, bruising, or bleeding at the injection site. In rare cases, fainting or infection may occur.

Reference range

Negative: < 20 AU/mL; Indeterminate: 20-30 AU/mL; Positive: > 30 AU/mLN/A

Specimen: serum

No fasting required. No special preparation needed. Inform the laboratory of any immunosuppressive medications or recent antifungal therapy.

Frequently asked questions

What is Aspergillus amstelodami?
Aspergillus amstelodami is a species of mold that is commonly found in the environment, such as in soil, decaying plants, and indoor air. Most people inhale this mold regularly without any issues, but some individuals may develop allergic reactions or infections.
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 contact you with the results or discuss them at your follow-up appointment.
Do I need to fast before this test?
No, fasting is not required for this test. You can eat and drink normally before having your blood drawn.
What does a positive result mean?
A positive result means that IgG antibodies against Aspergillus amstelodami were found in your blood. This indicates that your body has been exposed to this mold and has mounted an immune response. Your doctor will interpret this result in the context of your symptoms and other tests to determine if you have an Aspergillus-related condition.
Can this test diagnose invasive aspergillosis?
This IgG antibody test is more useful for diagnosing allergic forms of Aspergillus-related disease, such as ABPA. Invasive aspergillosis is typically diagnosed using other tests, such as blood cultures, imaging studies, or tests for Aspergillus antigens.
