Re: allergy testing 7 y/o
Well, there are several so you need to call and ask exactly which tests they are doing: scatch test, patch test, blood test, etc and find out exactly what the one they are doing entails.
I would not suggest telling her beforehand. The end of March is too abstract for her to understand. She be nuts from now till then. Tell her the morning of the day that the testing is to be done and explain, in general terms, what they will do.
