sequin style items to wear for the party

So my daughter had stolen a chocolate bar a couple weeks ago and ate it. We didn't find out till about 2 hrs later that she had done that and it had peanuts in it which she's supposed to be allergic to. She had absolutely no reaction whatsoever. sequin style items to wear for the party
Our Dr said she's still allergic and that we are just lucky. I am getting her blood tested anyway to be certain but is that possible? That we are just lucky?
