Addison's Allergy test

Today, we went to have Addison's allergy panel done. I was hoping for answers, just because I'm a fixer. All I want is to know the cause, and fix it!!!!! Buttttt, today, all 27 tests were NEGATIVE.... Yes, NEGATIVE!!!! So, the next step is to put her back on milk and see if her Eczema flares up. Just a waiting game. But that's ok. I know that the Lord will provide me patience, and knowledge to help my baby girl until we figure it out!!!
