We have a 23 month old who is severely peanut & egg allergic. We also have a three month old baby. We are limiting exposure to main allergens with our second child (as we did our first) and are hopeful she does not also develop allergies. When is the earliest we can have a useful skin test done ... I read 18mos somewhere ... is that correct? NP.

I'm not positive, but we did get my daughter blood tested at 6 weeks. She reacted to milk and just wanted it confirmed before cutting everything out of our diet(plus it's good to have a confirmed positive on record, I know some will argue the importance of testing...I test). They did skin test her as well, just this winter, so right before age 1. That's when egg showed up, we also did blood work again to get the numbers of the egg and again the milk.
Under age 3 their immune system is still developing, so you may or may not get correct results, but if it is positive, it's usually a low number. At age 3 it all peeks and the numbers become very high, but their immune system is fully developed so you can start checking for environmental and seasonal then as well. After age 3, their test results tend to come back down a bit(level out so to say)....(this is how it was explained to me by the allergist, so of course I could be wrong).

Thanks ... that is consistent with what I read. I'll probably bring our youngest in to see the allergist once we start introducing solid food, with the understanding that things could change. Our oldest displayed egg allergy at 8 months and had a slight swelling reaction after eating a muffin that had a stray nut in it at 15 months. So there is no need to wait until three =) NP.

Hi. I just wanted to add that my dd's allergist tested her at one year. I have also talked to many other pa parents who tested at similiar and even younger ages. Unfortunately, her rast level is as high now as it was when she was one. This is almost eight years now since her first test.

PA/TNA DD is almost 10. We treat her younger sister the same. Last year sister (4yrs) had a RAST that tested just for peanuts and it was negative. However, Dr. said this could be because she has not been exposed and therefore has not had the opportunity to form the antigens. However, I was glad to hear the test was negative and we still avoid peanuts and tree nuts. She is now 5 and will start kindergarten this fall. This summer I will take her for further testing- so if she is allergic then she will have the epipen for school etc. And if she isn't then I don't have that to worry about w/ her. I will also have my older DD tested, since she was tested at 6 and will be 10 soon.

But if she has never been exposed, as before with her test, what makes you secure now, if her test is neg. again? Just wondering. I am worried he will test neg. due to lack of exposure, but could react, and not have epipens at school. becca

For the test this summer- if the blood work is negative I'll request a SPT. If that is negative then I'll request a challenge in the office. She had an accidental minor exposure to peanut butter in icing on a birthday party cupcake when she was about 18mths. She just had a small taste- if anything at all- before I took it away and she was fine. She has been around peanut butter and has eaten some nuts successfully. She already tells people she's allergic to peanuts. I would just like to know for sure.

I can't say for sure w/r to PA specifically, but I do know what our experience was with TN. All the initial TN tests (RAST and SPT) were negative. So our allergist told us it was fine. We argued this point by pointing out that she had been diagnosed as PA via anaphylaxis so young that she really COULD be totally unexposed to TN. He didn't think we could have avoided trace exposure that successfully. So we gave her filberts very very cautiously. She liked them and ate them fairly sparingly over a period of about six months. We then gave her a few almonds to try. She ate about two at a time over a period of four or five days when we noticed eczema flaring after she ate them. Duly noted. Filberts around the same time resulted in a few hives on her back. Also duly noted. We tried these nuts only because we knew we had a safe uncontaminated source of them (living here in filbert-ville).
Retesting showed she is now (drum roll please) ALLERGIC to them both.
So my advice is that if your child tests negative, insist upon a challenge, and then retest to make sure.
Allergist listened to us when we wanted a test for pistachio. Thank goodness. That was the skin test that got used for show and tell. The sensitiztion was only having a nut shell in her mouth at about 9-10 months old. (shudder)
So if anyone tells you that you can't possibly have really prevented all exposure, DON'T LISTEN if you know you have been that careful.

Hmmm. We have been a nut-free home and dealing with dd's PA for 5 years. So, we have been that careful with him, as he is only 2!
I had the worst dream that he had an anaphylactic reaction, just before I woke today! It was weird because I had been given unsafe chocolate with nuts in it(in the dream) and it was in one of those bags that opened poorly, and it kept ripping a bit more as I scrambled to pick up pieces of the candy before ds did! On and on. I finally get it all cleaned up, and he wanders out of my closet with a PB cup! I do not have those in my closet, IRL, before you think I am a closet eater! Anyway, he has nibbled just edges off the chocolate and I am trying to get it away from him, and he is dodging me. I get it. Watch him, scrambling to clean him up. He gets horse. Dh is in bathroom, just going in to shower. I am alone to run *downstairs for epi*, and I only have expired Jrs. I have kept around for just such an emergency. He is limp in my arms. I could cry tying this(or throw up). Then, it is a dream, so I actually seem to have given him 1/2 of an adult epi(maybe all I could grab quickly enough). He is still for the longest time. Then cracks a smile at me, and says his tummy hurst!
How vivid is that??? I have never had such a dream for dd, my known allergic child. I think I fear the unknown more than what I do know. becca

I've asked Dr. Wood this question a million times. I am so worried about my 2 younger boys since the 2 older girls are so allergic. Basically, he said everyone gets some form of exposure.. breast milk, airborne, cross contamination. He recommends waiting till they are closer to age 4 before testing. He told me if they test negative with no symptoms to say otherwise I should feel comfortable they are negative. Jackson has tested negative twice to peanuts and nuts. He's never eaten one but just recently I've let him have something with a warning label of "may contain." He was totally fine. The preschool still doesn't give him anything and when I registered him for kindergarten I told them I didn't want them to give him anything with peanuts or nuts either.. a dietary restriction as opposed to an allergy. I'd prefer he not have anything he can bring into the house and contaminate.
I will let both boys eat birthday cakes and stuff from a bakery which I won't with the girls. SO I feel they are getting some form of exposure and I trust the tests to be accurate.
