Dh and I recently asked the allergist for a copy of our dd's skin prick test results. We are trying to get a 504 plan for dd for next year.

The allergist sent the numbers in the mail, but I'm trying to decipher them. Here is what the paper said

Peanut 20 mm wheal 50 mm erythema flare
Walnut 11 mm wheal 50 mm erythema flare
Pecan 13 mm wheal 45 mm erythema flare
Cashew 2 mm wheal 8 mm erythema flare
Almond 2 mm wheal 6 mm erythema flare
hazelnut 6 mm wheal 22 mm erythema flare
brazil nut 2 mm wheal 10 mm erythema flare
pistachio 0 mm wheal 2 mm erythema flare
pine nut 0 mm wheal 2 mm erythema flare

I couldn't find any information on erythema flare and what exactly the purpose is of measuring it. Any info on this?

However, my mother found this chart as a guideline for the other numbers (mm wheal)

0-2 negative
>2 but <3-5 mild positive
3-5 moderately positive
> 5 strong positive

Is this chart what other people have been told? What exactly do all these numbers mean? I'm assuming if this chart is correct, then giving the 504 committee a copy of these results would be a very helpful thing due to the fact that the numbers for peanut, walnut, and pecan were so high.

Any input or advice?

*sorry the numbers for her test results may be hard to read. I tried to space columns apart, but it didn't post that way!

And what are pseudopodia?? There was a notation about that for peanut and pecan.
I'm hoping someone can help me decipher this. I know we're all not doctors and I'm not asking for medical advice (well kinda, but not really!). Just need help deciphering this so I can sound somewhat knowledgeable when discussing results in a 504 eligibility meeting (whenever that may be!)
Thanks.

Hi Lori Anne, Some wheals are 'tidy' and round - others have pseudopodia - like little fingers or peninsulas that come out from the wheal, making it misshapen.
I've raised a thread for you that has a link to an excellent
South African web site that has lots of good info on interpreting skin prick tests.
Hope this helps.

Our allergist doesn't measure. It is either larger than the histamine control or it's negative in his opinion, KWIM? He doesn't think there is much correlation between wheal size and severity USUALLY...
Pseudopodia.... think of a shape like an octopus. (the root words here mean "false feet/limbs" if that helps) I gather they are unusual and that they tend to indicate extreme severity/sensitivity. DD's pistachio test looked like that-- like a regular very large skin test (>20 mm), but with feelers reaching out from it in all directions. She's never been skin tested for pn.
