When are allergy tests indicated for a person?

Allergy questions. Allergy tests are useful if you have questions about what you are allergic to and the answers will help improve your quality of life. They help guide avoidance measures and determine what immunotherapy options might be helpful in treating you. Sometimes, as with penicillin testing, they are most useful by telling us we don't have to avoid something any longer, we can add back things we feared.
