Hi - can anyone help.

We saw our allergist today re our 12month daughter. Her 3 year old brother has reacted to egg and kiwi (Rast scores 4) and rast tested 6 to peanut (no known reaction). Our daughter reacted to cod (on her first birthday!) and allergist is going to skin prick test for this on Wednesday. Our son has recently been treated with Chinese herbal medicine for severe eczema with amazing results and I'm keen to see if these have had any effect on his food allergies (chinese doc seems to be hinting they may have done). Our allergist (who doesn't know about the chinese treatment - he is anti non-conventional medicine) has offered to test our son at the same time. It is 15 months since his first and only rast tests. My question is this - if his IgE antibody levels to peanut have begun to come down (due to chinese treatment or maybe even outgrowing) will injecting a small amount of peanut allergy which I believe is what happens with the skin test cause his IgE antibody levels to peanut to rise again.

Would be grateful for your views.

I really can't give you any advice on whether or not that will effect the Antigen levels as my PA son has actually only been skin tested (not RAST tested). I never really thought much about it until lately when I have been reading so much about RAST testing I am wondering why he never did that. When my son's skin test was done, he was 18 months at the time, he was not really injected with it. A tiny, tiny drop was placed on his skin and they just pricked his skin (barely) at the point where they had put the drop. His reaction amounted to a small mosquito bite pimple which indicates a positive reaction. He didn't have any additional reaction to it. I know I have heard that people are concerned about the skin test because of the exposure, but my allergist never even mentioned a concern about it and I guess at the time, because I was so new to the whole food allergy thing, I never even questioned it.

Jacob has been skin-pricked twice now. The first time he was tested for every food imaginable. The second time he was only tested for 6 things. His first test he reacted to peanuts, cashews, pistachios and dust mites. His welts were as big as grapefruits. The second test he reacted positive to the above and also to almonds, sesame, and salmon. The last two were small bumps so they could be false/positive but I do think he reactes to sesame slightly. Anyway, during the twenty minutes that you wait for the allergist to return, he started complaining of his throat itching, then he experienced diarhea, and then he started coughing. They gave him a dose of Benadryl and all subsided rather fast but I will never have him skin-pricked again.
The kind of test that you are describing is, I think, the ID skin test. They inject a small amount, using a needle, under the skin. I had this done on my forearm after my skin-prick testing. It is more uncomfortable than the skin-prick but they rub cream on your skin to numb it prior to testing. However, this did little for the pain in my situation.
Let us know how it goes!

Hey Naomi -- Your son's reactions on the skin prick test resulted in grapefruit size welts??? My son's peanut test was slightly larger than a mosquito bite if that and they acted like it was a major reaction.

Jodi-
Yes, they were much larger (the size of a grapefruit) with the first test. A few months ago, when he was tested again, they were about the size of an orange (except for the sesame and salmon). I was extremely excited to see that they had reduced in size. However, the allergist explained to me that it was still extremely severe. I still have slight hope that he may be outgrowing this. I truly doubt it. One speculation that I have is that when he was tested the first time it was only a week after his last anaphylactic reaction. He was surrounded by people eating nuts and he was constantly reacting. I am wondering if his welts reduced in size because he had not been in contact with the allergen for quite some time.

Philip's skin prick test created a welt larger than a golf ball, smaller than a baseball - but then they removed the allergen early. He began developing satellite hives all over his back, most of them quarter size and growing. I can only imagine how large his original prick site could have grown had they left the serum on for the prescribed test time.
We'll never do the skin testing again - bloodwork all the way from now on.

Phillip's Mom-
I absolutely refuse to allow Jacob to be skin-prick tested again. The satellite hives sound scary. Jacob didn't experience that but he did experience psyuedopods (sp?) around his welts. They extended out all around the welt and made it look like a sun.

I wonder if it is a good sign that my son will outgrow his PA since his reaction to the skin test was much smaller in comparison to what your explaining. Won't get my hopes up yet as I can't imagine it going away any time soon given the reaction he did actually have the first time he ate peanutbutter. Guess I need to go talk to his allergist as to why he hasn't done the RAST test on him. Why do I sometimes feel I have to be the doctor when I have a doctor that is treating him?

We also will never do any skin testing again. It was horrible. It was painful for my son, and the results were nothing that changed our life. His back was a mess of welts for WEEKS and I already knew what it told us. Rast tests have been what has answered our questions, and that is all I plan on doing in the future.

Thanks for your advice everyone. As it happens the allergist did not skin prick test Tom at all because he had only been off Zirtek for 2 days and he needed to be off it for 7 days before prick tests would be accurate. He said to ring him when we wanted to do this but I think i'll stick to RAST tests.
