It was two blood tests. I think one was tryptase. I don`t remember the name of the other one. They are reactants in the blood that go up during an allergic reaction. They only stay up for a few hours (can`t remember exactly how long, but you have to have the blood drawn pretty quickly).

I have been thinking about this since that other thread as well... I know that one is "serum Beta-Tryptase" (which is notoriously unreliable [i]on its own[/i] for food-induced anaphylaxis...)
the other one, though.... might be serum Histamine?
Histamine may only be elevated for a period of minutes, which is why it can only very rarely be used to establish COD in autopsies. So that might be it. They pretty much have to draw it [i]during[/i] a reaction.
I'm trying to think what other analytical targets there are in that chemical cascade... Hmmm.

I am not sure the other one was beta tryptase. Is there just a regular tryptase? Whatever it was, it stays up for a few hours after a reaction and does not have to be drawn during a reaction. It was two different things, and they must be fairly unusual tests, since we had to go 5 miles away to the hospital to have it drawn.

We have two plans--one for home when we might not give epi immediately for limited symptoms. However, we are rethinking that approach for three reasons: 1. immunologist says research/medical evidence shows that best survival comes from epi within first 5 minutes 2. evidence that epi is not harmful and does not have ill effects 3. what message does it send to our son whom we want to encourage to use epi without hesitation--better to walk the talk and use the pen--immunologist and family doctor concur and suggest that only harm can come from waiting and nothing is lost by administering
FOR THE SCHOOL THOUGH --our plan has always said that we expect epi to be used whenever it might be needed--if they are thinking about whether to do it then they must do it--there is no harm to our son if they use it and consequences of not using it can be catastrophic
