As the families of Violet Rivera, Adrian Guzman and Gabby Weaver discovered, eating a food is often the best way to rule out – or overcome – an allergy to it.
“Skin and blood tests are often inaccurate in diagnosing a food allergy,” says food allergist Christina Ciaccio, MD. “An oral food challenge is the only way to know for sure.”
After eight-month-old Violet got hives from eating scrambled eggs, the Dyer, Ind. family was referred to Raoul Wolf, MD, for allergy screening. When Violet tested positive for egg and peanut allergies, she was scheduled for a peanut challenge with Dr. Ciaccio. She was able to tolerate the peanuts and is now eating them three times a week, which will help prevent the development of a severe peanut allergy.
