About this test

After a strong reaction to a yellow hornet sting, this blood test can check for IgE antibodies to yellow hornet venom. Decisions about venom allergy care are made with an allergist. A positive result shows sensitization, which is not the same as an allergy. No fasting is needed.

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

Who should take this test?

This test is for adults with a past strong reaction to a yellow hornet sting who are working with an allergist and want to check IgE to yellow hornet venom.

What does this test measure?

The result shows your level of IgE to yellow hornet venom, one piece of information an allergist reads with your sting history when planning venom allergy care.

Yellow hornet venom-specific IgE (i5)
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes yellow hornet venom, reported in kU/L. A level above the lab’s reference range means sensitization, not necessarily allergy.
Why it’s measured: Read by an allergist with your sting history to guide venom allergy care.

What your results tell you

The lab reports an IgE level in kU/L and compares it with its reference range. A level above that range means you are sensitized.

Questions

Common questions.

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

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

Once you are well, an allergist or other healthcare provider can help you decide whether testing fits and what comes next.

It does not tell you whether you will react to yellow hornet venom, or how strongly. IgE shows sensitization, and many sensitized people have no symptoms. A negative result does not clear an allergy either.

Decisions about venom allergy care belong with an allergist or other healthcare provider who knows your history.

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.

Lab tests are informational and don’t diagnose conditions on their own. Available to adults 18 and older; test availability varies by lab location. A licensed clinician reviews your order and, if appropriate, orders the test. All testing is performed at CLIA-certified laboratories. Not for emergencies: if you think you may be having a medical emergency, call 911.
