Hello ... what type of tests has she had? Skin, bloodwork and what are the results and her age and exposure. I'm a mom of a daughter who has grown "into" her allergies and with repeated exposure her reactions have progressed. But I need the info above to give you my two cents as a mom, and of course, discuss with her allergist thoroughly.
Also, what are her reactions, if any? You can test + thru blood or skin, yet not have any symptoms.
20% of children outgrow peanut allergy - you will only know through your allergist office. Stay in close contact.
