Talk to Internal Medicine on Allergy Test- Report Review

My 3 yr daughter started having hives on her body last year she would randomly get it on most parts and then after giving rigix it would subside, the first two times it was a big flare up then later on she’d 6/7 hives here and there, this continued till this year we got rid of a domestic cat in our house some months ago and now since then she hasn’t got hives since 4/5 months except sometimes only when a mosquito bites her then that develops in a hive and settles down in a while itself or sometimes after an anti allergic. In November we got her IGE levels checked which was high so we also got her allergy test done both food and environmental of which the report says that she’s mildly allergic egg whites. Now i have two questions 1) Ive never seen her reacting to egg as she takes it daily almost, secondly the hives last year also didn’t stop when we had stopped giving her egg. 2) i was expecting this test to be very detailed as there are alot of other foods/environmental allergens ment
