Hi all! I'm looking for some answers.

When my daughter was 7 1/2 years old she was diagnosed with a peanut allergy via a blood test AND a skin test. During the skin test, the site for the peanut allergen reacted almost immediately and grew a rather impressive welt.

(As a small child from about age 3 to age 5 she would also be physically sick several hours after eating peanut butter, but we didn't ever think it might be an allergic reaction. Duh.)

Now, today...she had an allergy retest via a skin test. And, all of her food allergies showed up as a 0 (on a scale of 0-5). This includes the peanuts, along with corn, soy and sesame seeds.

Is it possible for all food allergies to just 'disappear', even a peanut allergy? The physician's assistant and nurse were like "oh it's not a big deal" and even said "wow! that's the second time that's happened today!"

I pushed back and demanded that they figure out how this happened, so we are going through a blood test for peanuts and all nuts.

Has this ever happened to anyone? Can a peanut allergy just vanish in 18 months?

Our allergist stated and I also read in the Peanut Allergy Answer Handout that kids have a 20% chance of outgrowing peanut allergies. The nut allergies are harder to shake but often the other ones do go away. Your child may have just won the allergy lotto but I would wait for the blood test. I assume this was in an allergist office. Our allergist in Ann Arbor, MI said that if our 2 year old's levels decline over time that they do a challenge in the office with an epi pen ready. If they think that your child may have improved - I would make sure you are in a medically supervised environment when trying any of the foods (especially nuts).
