What is this test?

This test measures the total amount of canary grass–specific IgE antibodies in a blood sample. IgE is an immune-system protein that can form in response to exposure to an allergen such as pollen.

Why might I need this test?

It may be ordered when symptoms such as sneezing, watery eyes, nasal congestion, wheezing, or hives occur after exposure to grass pollen. It can help identify whether canary grass is a possible trigger.

How is the test performed?

A blood sample is collected and analyzed in a laboratory for IgE antibodies that react with canary grass allergen. The result is reported as a measured amount or according to the laboratory's testing method.

How do I prepare for the test?

No fasting or special preparation is usually required for this blood test. Follow any instructions from your clinician, and do not stop prescribed medications unless your clinician advises you to do so.

Frequently asked questions

Does this test diagnose a canary grass allergy?
No. It indicates whether the immune system has produced IgE antibodies to canary grass, but a positive result must be compared with your symptoms and exposure history to establish clinical relevance.
Is this the same as a total IgE blood test?
No. This test measures IgE directed specifically against canary grass, while a total IgE test measures the overall amount of IgE in the blood.
Can I take allergy medicine before this test?
The test is generally a blood test and usually does not require stopping antihistamines. Follow your clinician's instructions, especially if additional allergy testing is planned.
