DS was supposed to have skin test done this Thursday, but broke out in hives last night at soccer practice. Who knows what got to him - just his cheeks broke out. Weird. Allergist said he's supposed to be off antihistamines for 5 DAYS before having the test done and we were only two days away! Argh! We rescheduled for next Thursday, but now I'm worried he won't be able to go 5 days withoug the anti-hist. Anyone else have a problem like this? Maybe we should just do a RAST again. He's almost 4 and hasn't had one done since he was 18 months.

How frustrating! I've always heard that you need to be off slow-release antihistamines (like Zyrtec) for 7 days (or something like that. I forget the exact number), but you need to be off quick-release antihistamines (like Benadryl) for only 48 hours. Maybe the dr. wants to make sure that his system is back to normal before doing the skin test? If so, it might be longer than 5 days.

We live like hermits the week before skin testing. We try to do it in the summer (ds's worst allergies are spring and fall) and never over the winter because of asthma and colds, we don't chance going off the antihistamine. We also have everyone be EXTRA careful if they come to visit. I believe Benadryl can be given up to 48 hours prior.

It's always a challenge...we've used Benedryl as little as 36 hrs prior when we had to, and doc said it was fine... that was the time we had the pistachio result the size of a silver dollar with pseudopods, though.... hmmmm... wonder if THAT was a reduced reaction.

anyway, we always hold our collective breath as well. Sometimes ice packs or a tepid bath will help mild hives without the antihistamine. (We oughta know)
We always do skin testing in fall... no ragweed here! [img]http://uumor.pair.com/nutalle2/peanutallergy/tongue.gif[/img] (But before you sign up for the NW, you need to know about grass pollen season.... whooooeeeeeee. May through July... highest numbers in North America.)

It is so reassuring to know we're not the only people to schedule tests for when ragweed (or whatever) is lowest.

Personally I would go for the blood test Where you can compare results. & you can always have a skin test later in the year.
He is ony 4 & his system isn't even fully developed so why chance the expossure.

I'd do the RAST as well... and if things come back negative, then SPT those...
Unless rast testing has given bad results in the past (false +/-'s).

We haven't done a SPT since dec 03 b/c Aidan can't get off of his zyrtec without everything flairing. Our allergists doesn't trust the rast, but it works for so many people so good luck on what comes of what ever test you do.
Take care,

We had some negative RASTS so SPT those allergies possibly outgrown (which tested 2+ on SPT), did not retest peanut as he still had a number for that. Also did more environmental testing d/t problems in the spring/fall, all negative.

Thanks! Nice to know others have had the same problem. I think if we can't get to next Thurs without a reaction, I'll just take him in for a checkup (we need refills anyway) and ask the dr for a RAST. That'll give me some clue as to how his PA is doing since the one he had done when he was 18 months. Fingers crossed!
