About this test

This blood test checks for IgE sensitization to pigeon feathers. People often check it when symptoms follow time around birds or feather bedding. Sensitization is not the same as allergy, so the result is read with your history. There is nothing to do ahead of your visit.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

Adults often use it when symptoms follow time around birds or feather bedding, or before an allergist visit, to check sensitization to pigeon feathers.

What does this test measure?

The result shows your level of IgE to pigeon feathers, one piece of information an allergist or other healthcare provider reads with your symptoms and exposure history.

Pigeon feathers-specific IgE (e215)
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes pigeon feathers, reported in kU/L. A level above the lab’s reference range means sensitization, not necessarily allergy.
Why it’s measured: To see whether you are sensitized to pigeon feathers, read with your exposure history.

Questions

Common questions.

No. Sensitization means your body has made IgE to pigeon feathers. An allergy means that exposure causes symptoms. Many people are sensitized without having symptoms, so a positive result alone does not mean you are allergic.

A negative result does not clear an allergy either. An allergist or other healthcare provider reads your result with what happens when you are exposed.

Feathers and droppings carry bird proteins that can lead to sensitization. For pigeon feathers, exposure can come from city streets and pigeon lofts.

Birds can also cause a different lung reaction that does not involve IgE, and this test does not check for it. Ongoing cough or shortness of breath around birds needs a healthcare provider. A positive result shows sensitization, not that birds cause your symptoms.

Both look for IgE sensitization. A skin test checks how your skin responds to a small amount of an allergen, while this test measures IgE to pigeon feathers in a blood sample. In many cases the two are considered comparable.

A blood test may be preferred in some situations, such as a widespread skin condition or recent use of medicines that affect skin tests. Don’t stop or change any medicine without talking with your healthcare provider.
