How can you know if you have a bee sting allergy if you have never been stung?

Can't prognosticate: Insect sting allergy can be tested for once a suspect anaphylactic reaction has occurred, however testing with no history of anaphylaxis is not indicated. Nor is there data to assist in interpreting skin test or in vitro (blood) tests in the absence of a positive history. Additionally as with any allergy there is the requirement of prior exposure(s) to induce sensitization necessary for allergy.

One does not know: Bee sting allergy is diagnosed after an individual is stung, has an allergic reaction and skin testing and/or blood testing verifies the offending allergen.
