I`m not sure if I have seen that or not. I usually don`t pay attention to what numbers people will do a peanut challenge at, because we are NEVER in that ballpark! And since dd is 10, I know it isn`t going to be outgrown. She will never get a peanut challenge. Yes, 10 seems really high.
About the milk, that is strange. I can never understand how someone can have a positive cap rast and no reaction unless it was really close to normal?

His milk was 1.73 and soybean was 3.75. He also had skin tests for both and they were positive but the allergist said they were low enough. I also stressed he had eaten these things many times without a reaction. The allergist did advise to stay away from heavy soy products...tofu,etc.
Sorry to hijack this thread!

When you say her test came back low enough to do a food challenge using real live scrambled eggs, are you talking about a RAST? Did he do a skin test after getting the blood results? My younger son is allergic to eggs, and his last RAST came back negative. So we were guardedly optimistic, but he showed up positive still when a skin test was done to double check. I would guess there are other members, with way more experience than I, that could speak to this whole process. I, personally, would be nervous going straight from RAST to food challenge. I know though, that recently there have been members that have had food challenges lately, that could definitely add info here.......any of you around?

Tamie,
First off, congratulations! It certainly sounds promising. I would also think a skin test is in order b/f heading for the food challenge or will they do that the same day? Last summer ds went for a peanut challenge and there was a little girl there challenging egg who passed with flying colors! We didn't fare so well. The challenge can take a long time. Bring books, games, etc. BTW, you said dd is pa so beware in the waiting room for others challenging peanut.

DD (PA, TNA, dairy and egg allergies) tested low enough by RAST for an egg challenge two years ago (at age 6). We did not do a skin test because there is a high rate of false positives. That is, the skin test can remain positive for a long time after a person loses an allergy as judged by lack of reaction to eating the food.
The challenge took place in the allergist's office (in a hospital) with a nurse practitioner in attendance and the allergist in the same clinic area. It was very safe. We were asked to bring homemade french toast (bread that we knew was safe dipped in one whole egg and fried in safe oil) with safe syrup so that she wouldn't hate the taste of egg which she had never eaten before. We started with a tiny amount and over the course of one and one half hours she ate about three quarters of one piece of french toast. She actually liked it.
Near the end of the challenge, she started to complain of abdominal pain and nausea. This was considered a positive reaction and she was still considered allergic. The symptoms seemed to improve after some Benadryl. That was it: no hives, no trouble breathing, etc. We have been avoiding eggs since then (just as we did before the challenge), and her RAST level has risen slightly (around 2). Every year we repeat her RAST and when it falls below 2 we plan to do another egg challenge.
The funny thing is that the night of the challenge DD developed a fever, nausea and vomiting which were considered to be viral. So we don't know if her "reaction" was a true egg allergy or just the beginning of a viral gastroenteritis. We haven't been more aggressive about pursuing another egg challenge sooner (even though I think she is probably not still allergic to eggs) because it is not that difficult to live with an egg allergy when you are also avoiding dairy, peanuts and tree nuts.
Hope this helps and good luck!

Hi, my dd passed her egg challenge at age 9! They don`t skin test after a negative rast because 50% of the time the skin test remains positive after they have outgrown the allergy, so a skin test is great for telling you about a new allergy, but does not tell you if they have outgrown it. My dd had an anaphylactic reaction to egg at age 2 1/2 requiring epi, so if there was anyone who wasn`t going to outgrow it, it was her. Her cap rast to egg at age 9 was 0.11 with normal at age 9 being less than 0.10. She had several different forms of egg during the challenge. She had egg salad with real mayonaisse, scrambled egg, and I don`t recall what else. They had me give a tiny amount, wait a few minutes (don`t recall if it was 15 or 30 minutes), came back in and checked her, gave a larger amount, and so on. The whole thing took about 2 or 3 hours. I also remember making some merangue for her, since it is from raw egg, so it would be a really good test, but I am not they ever had me give it. Anyhow, she passed and that was a year ago.

Carefulmom: Do you remember your daughter's RAST number for egg, when she was young?

They didn`t have a cap rast back then. She had one at age 5 and I think it was a class 2.

Oh, sorry he did not do a rast when she was younger (back before cap rast) because she had had an ana reaction and had a positive skin test, so what was the point. He did the cap rast at age 5 to see if she was outgrowing it, since the skin test often remains positive.

Like BS312 we did our challenge with French Toast. RAST was in acceptable range for testing. We cooked 1 slice of safe bread dipped in 1 beaten egg mixed with a little water and fryed in butter at home and brought to hospital (Allergy Clinic) to eat. (I can't imagine anyone diving into scrambled eggs who have never had them - I think the french toast is a better idea)!Also brought safe syrup. Started with a piece the size of a pencil eraser. Waited 15 minutes. Then a piece twice the size of a pencil eraser. Another 15 minutes. Then double that amount, etc. until we got to the 1/4 of a piece of french toast (equavalent to 1/4 cooked egg) and then the doctor said he was starting to react. I didn't even see it, but he noticed the very beginnings. Change in attitude (wanted to leave NOW), glistening eyes, restlessness, very slight sniffles. He said it was the start of anaphylaxis so in went the epi, steroids and another medication I can't remember. We had to wait 4 hours (good think we brought movies with us - it was the year of Lion King so that was a while ago!). After 4 hours we were allowed to leave, but he did need to be on steriods for 5 days after that. For us, no go. He's 13 now and his RASTS are too high to challenge again. We'll do one more RAST next year and then that will be it. He's probably a lifer!

P.S. The only downside for us - to this day, he hates the smell of syrup!
