Allergy re-testing (skin test and oral challenge)

We went to the Hospital for Sick Kids -Toronto - yesterday to have my DD and DS's allergies tested. We arrived at the hospital at 12:30pm and left at 5:20pm. My DH was NOT a happy camper that we were there sooooooo long. My DD was re-tested for Peanuts/Tree Nuts and tested positive again to Peanuts and negative again to Tree nuts. The reaction this time for Peanuts was quicker and more severe than the last time and the 'doctor' took her to show the other doctors the swelling on her arm. I think alot of teaching goes on at this hospital (part of the reason it was a LONG visit). I didn't really think she would outgrow her allergy but I didn't think she would be more severe either!!! [img]http://uumor.pair.com/nutalle2/peanutallergy/frown.gif[/img] My DS was SUPPOSE to be tested for Insect bites but he wasn't. I don't know if the staff didn't read the referral or what!! The doctor talked to us about his reactions so far and then said -- if someone is tested for Insects they do not use a skin prick test but rather needle injections just under the skin which need to be arranged ahead of time ---- I thought 7 months was enough time to arrange it since this is when the referral was made but I guess not. The doctor also said that since my DS hasn't experienced any difficulty in his breathing to just wait and see and give him Benadryl for any reaction. Hmmmmm his WHOLE face swelled -- his eye lids were just slits -- the last time he was bitten!!! Guess that wasn't severe enough!!:roll eyes: Go figure!!! My DS WAS tested for Peanuts and Tree Nuts (which was not the reason for him being tested; I only asked for this when we arrived at the hospital), his skin tested was negative -- to both serum and actual peanut butter -- but since he has never had peanuts/nuts before this wasn't a true reaction to the test so they gave him an Oral Challenge.

My DD had to leave before this took place [img]http://uumor.pair.com/nutalle2/peanutallergy/eek.gif[/img] --good thing my DH was there to take her elsewhere -- I didn't plan on an oral challenge happening. My DS had to eat peanut butter cups, which I had to go and BUY first. He ate 2 peanut butter cups which he gobbled up very fast probably because it was getting close to meal time then he had to wait 10 minutes then have a check up -- had his blood pressure taken etc. Everything was fine so he then had to eat the last peanut butter cup -- this time he took one bite and didn't want anymore. He said he didn't like the taste of the inside only the chocolate on the outside. The doctor didn't push him to eat anymore. We had then had to wait 20 minutes before they checked him again. This time his pulse had dropped so they checked for hives which he had none. They didn't do any further testing. On the way the drive he was drooling abit and when we were getting him ready for bed he complained that his tongue hurt so I gave him Benadryl. We checked on him throughout the night and he seemed fine.

He has to go back in a couple of months for another skin test which should be a true test to show whether or not he has a peanut allergy now that he has had peanut butter in his system. My DD doesn't need to be tested again for 2 years since she is "VERY allergic" according the the doc's and they don't forsee her out growing the allergy but without exposure to peanuts/nuts or "May Contain" products who knows things could change the next time. Has anyone had an easy time when it comes to allergy testing??

Our first 2 visits with the allergy dr. here in usa were very long also. the interview, skin testing and post consult were 5 hours each time. We haven't even gotten to the more extensive food panel. The kids 6 and 4 are both pa. My 6yo ds had a similar reaction to a wasp sting. They ordered us to admin benedryl and prednisone just in case (due to the history of anaphlaxsis with my 4yo dd). My husband was out of his mind by the end of the appt. They started imunotherapy which will help with their pollen,dust,animalmolds ect. I hope all of this has gotten less frustrating for you. I know we are still very frustrated and even confused. Hang in there, Melody

My son had part 2 of his peanut/nut testing, a skin test and it was negative. The doctor wants him to have a blood test to confirm the skin test, but I don't think I will have this done.

Now, we don't have to see an allergist for 2 years!! At which point my daughter will be tested for peanut and environmental allergens and my son for environmental allegens.

Codyman...Is your son then not allergic to peanuts? What do you think caused the drop in blood pressure and the drooling after eating the peanut butter cups during the food challenge? Has your son eaten peanuts since then with no reaction? I am very interested because we are also going through our own testing/diagnosis nightmare. Thank you.

I have had life-threatening reactions and tested negative. Just to be aware, legumes are cross-reactive. You may get false positives/negatives within the group. The deadly ones for me are peanuts and soybeans, but in 2001 I tested positive only for soybeans and peas and in 2003 I tested positive only for peanuts and peas. I had never ever reacted in any way to peas. My reaction earlier this week was to accidental ingestion of soy. So just be reeeeeally careful about reintroducing.

It's now 2 years later and I took my children to the allergist for re-testing. DD skin test, still positive for peanuts and nuts. DS skin test, POSITIVE for peanuts and nuts [img]http://uumor.pair.com/nutalle2/peanutallergy/frown.gif[/img] This was a BIG surprise and I had to check the whelts Twice to make sure it was correct. He now has an epipen. Thank goodness his Grade 1 teacher taught my PA daughter and I don't have to educate her.

Haven't told my family yet, I suspect they will be shocked, as I am right now.
