This test is a medical diagnostic procedure in which a sample, such as blood, urine, or tissue, is collected and analyzed in a laboratory. The results help your health care provider evaluate how your body is functioning, screen for disease, confirm or rule out a suspected condition, and monitor an illness or treatment you may already have.

The Acremonium sp. IgE antibody test is a blood test that detects whether your immune system is allergic to Acremonium, a common type of mold found in soil, decaying plants, and indoor environments. The test measures two things: specific IgE antibodies against Acremonium and your total IgE level (the overall amount of IgE antibodies in your blood).

Your provider may order this test if you have symptoms that need an explanation, as part of a routine checkup or preventive screening, before or after certain procedures, or to track how a known condition is responding to treatment. It may also be used to check for possible side effects of medicines you take or to establish a baseline before starting a new therapy.

Your doctor may order this test if you have symptoms that suggest a mold allergy, such as sneezing, runny nose, itchy eyes, wheezing, or difficulty breathing. It is particularly useful for diagnosing allergic conditions like allergic bronchopulmonary aspergillosis (ABPA), asthma exacerbations triggered by mold, or other respiratory allergies. The test helps determine if Acremonium mold is the cause of your symptoms.

The test is usually performed by a trained health care professional. Depending on the sample needed, a small amount of blood may be drawn from a vein in your arm using a sterile needle, or you may be asked to provide a urine, saliva, or swab sample. The collection typically takes only a few minutes, causes little discomfort, and the sample is then sent to a laboratory for analysis. You can usually return to your normal activities right away.

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 analyzed to measure your IgE antibody levels. You do not need to fast or make any special preparations before this test. The procedure only takes a few minutes and is generally well-tolerated.

Your results are compared with established reference ranges, and your provider will explain what the values mean for your specific situation. Normal results generally suggest no evidence of the condition being tested for, while abnormal results may point to infection, inflammation, organ dysfunction, or another issue that needs further evaluation. Abnormal findings do not always mean you are ill, so additional testing or a follow-up visit may be recommended before any diagnosis is made.

Results are typically reported as a numerical value (kU/L) for both the specific Acremonium IgE and total IgE. A higher level of Acremonium-specific IgE indicates that you have developed antibodies against this mold and may have an allergy. Your doctor will interpret these results together with your symptoms and medical history to make a diagnosis and recommend appropriate treatment.

Reference range

Total IgE: Age-dependent reference ranges (typically 0-100 kU/L for adults); Specific IgE to Acremonium: <0.35 kU/L considered negative; 0.35-0.70 kU/L low positive; 0.70-3.50 kU/L moderate positive; 3.50-17.5 kU/L high positive; >17.5 kU/L very high positiveN/A

Specimen: serum

No special preparation required. Patient may continue antihistamine medications unless otherwise instructed by ordering physician. Inform laboratory of current medications especially antihistamines, corticosteroids, or immunosuppressants.

Frequently asked questions

Is this test painful?
The test involves a simple blood draw, which may cause brief discomfort or a minor sting when the needle is inserted. Most people tolerate it well with minimal pain.
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 stop taking allergy medications before the test?
Unlike skin prick tests, blood tests for IgE antibodies are not significantly affected by antihistamines or other allergy medications. However, always follow your doctor's specific instructions regarding medications.
What happens if my results are positive?
A positive result means you have IgE antibodies against Acremonium, indicating an allergy to this mold. Your doctor will discuss treatment options, which may include avoiding exposure to mold, using medications to manage symptoms, or undergoing allergen immunotherapy (allergy shots).
Can this test diagnose all mold allergies?
No, this test only checks for antibodies against Acremonium mold. If you are allergic to other types of mold, additional tests may be needed to identify all relevant triggers.
