If you got a call in September, and then just got a letter from the allergist, why didn't the nurse just ask the allergist what results they were looking at? Your allergist wouldn't go through all that without having results to base what they are telling you off of right? That really would be a nurse saying, "let me talk to the allergist and call you back" type of thing.
It all sounds weird. And, like you, I would definitely want to see, for myself, what the lab results are now at this point. On paper. In my own hands.
I also still might question the nurse about what the allergist was looking at.... if there is something that is actually in my child's file. And checking the dates.
