About this test

This test measures IgE antibodies to yellow jacket venom. People often check it after a strong reaction to a yellow jacket sting, alongside care from an allergist. A positive result shows sensitization, which is not the same as an allergy. 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?

For adults who have had a strong reaction to a yellow jacket sting and want to check for sensitization to yellow jacket venom, alongside care from an allergist.

What does this test measure?

Your result shows whether your blood has IgE to yellow jacket venom. An allergist reads it with what happened after the sting to decide on next steps for venom allergy care.

Yellow jacket venom-specific IgE (i3)
Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes yellow jacket venom. A level above the lab’s reference range shows sensitization, which an allergist reads with your sting history.
Why it’s measured: Checks for IgE sensitization to yellow jacket venom after a strong reaction to a sting.

What your results tell you

Results come back as an IgE level in kU/L, compared with the lab’s reference range. Above the range shows sensitization, not necessarily allergy.

Questions

Anything else, our care team answers by phone, text, or email.

No. This test is not for urgent reactions. If you have trouble breathing, swelling of the face or throat, or you faint after a sting, call 911 or get emergency care right away. If you have a prescribed epinephrine auto-⁠injector, use it as directed.

Once a reaction has passed, an allergist or other healthcare provider can help you decide on next steps, including whether testing fits.

Not on its own. A positive result means your immune system has made IgE to yellow jacket venom, which is called sensitization. Many people who are sensitized have no symptoms when they are exposed.

A diagnosis of allergy is made by a healthcare provider who looks at your symptoms and history along with results like this one. A negative result also does not by itself mean you are not allergic.

An allergist. Decisions about venom allergy care are made with an allergist, who looks at what happened after the sting, which insect was involved if known, and results like this one.

Timing matters: a test done soon after a sting can read lower, so an allergist can advise when to test. A negative result does not clear a venom allergy, and a positive one does not tell you how you would react to a future sting.

Yes. Yellow jacket venom is one of the venoms in the insect venom panel, which measures IgE to several stinging insect venoms in one draw.

Each result in a panel is read the same way: sensitization is not the same as allergy, and an allergist reads it with your history.
