About this test

This blood test checks for IgE sensitization to fire ant venom. People often check it after a strong reaction to a fire ant sting, alongside care from 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?

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

What does this test measure?

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

Fire ant venom-specific IgE (i70)
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes fire ant 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.

  • Your number next to the lab’s reference range
  • Explained in plain language
  • A licensed clinician reviews your order and, if appropriate, orders the test.
  • A lab report you can download and share

An allergist reads this result with what happened after the sting. Decisions about venom allergy care are made with them.

Questions

Common questions.

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

Get emergency care. If you have trouble breathing, swelling of the face or throat, or you feel faint or pass out after a sting, call 911 right away. If you have a prescribed epinephrine auto-⁠injector, use it as directed. This blood test is not for urgent reactions.

After a serious reaction, an allergist can talk with you about what happened and which tests make sense.

No. Sensitization means your body has made IgE to fire ant venom. 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.

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. Fire ant venom is one of the venoms in the insect venom panel, which measures IgE to several stinging insect venoms in one draw.

Panel results are read like single tests. Sensitization is not the same as allergy.
