Hymenoptera Venom Allergy Panel in Arizona

What this test measures

Stinging insects inject venom when they sting, and for some people the immune system produces IgE antibodies against proteins in that venom. A subsequent sting can then trigger an allergic reaction, which may range from local swelling to a body-wide response. Identifying which venoms are involved helps a clinician assess risk and discuss management.

The test uses a blood sample to measure allergen-specific IgE for five venoms: honeybee, paper wasp, yellow jacket, yellow hornet, and white-faced hornet. Each venom is reported separately with a level and a reactivity class. Because some insect venoms share proteins, cross-reactivity is possible, and the pattern of results can help clarify which insects are most relevant.

A positive result shows sensitization to a venom, not the severity of a future reaction. Some people with positive tests never react strongly again, while others do. A qualified healthcare provider uses the result with the sting history, symptoms, and other findings to guide the discussion, and anyone with a history of a severe reaction should seek medical guidance.
