My non pa ds' overall IGE was 388 2 yrs ago. The scale on the test says:
< 18 Negative for Atopic Allergy
18 - 158 Equivocal for Atopic Allergy
>158 Probably Atopic Allergy
His dr. always refers to him as highly allergic. He is allergic to latex and bananas and others, people have a hard time believing it is a true allergy. Dr. just says he is very atopic. Sorry to whine, we all have our difficulties to deal with. His brother is pa.

My son's total Ige was:
age 3 1358
age 5 465
This seems like a pretty drastic decrease in two years. But with future exposure to the allergens, the body would produce additional Ige and the number would increase.(hopefully not on both accounts)

My allergist wouldn't give me a copy of my son's test and called in the results.
When I go back in May I'll have to ask him what his IgE level's were. I didn't know that it could be a factor in changing the score. Anyway on the CapRast he was 9.43
And Jill, you weren't whining at all, that's a heck of a lot to deal with. You guys all have the right to whine here on these boards.

Maybe I can help clarify the confusion about the Total IgE and specific RAST IgE tests. i encounter these every day. In my job at the hospital, I work in the lab. We send these out regularly on allergy patients...And we just got my PA son's results back this week.
Total IgE is the amount of IgE antibody that is circulating in the blood. Ig is also called and immunoglobulin. There are various types of immunoglobulins in the blood, but IgE is specific for allergy. The total IgE is the TOTAL amount of IgE or immunoglobulin E that is in your blood. It is indicitve of allergic response. Depending on what you are allergic to- the total count would be all of those substances added up. Make sense?

The RAST test is IgE specific, in that it counts the amount of IgE for a particular allergen (peanut for us). WHat happens in the body is that we have IgE (also called anitbody) that is in our system. When the offending substance (called the antigen) enters the body, the antibody binds with the antigen. (our immune system looks as it as if it were foreign and "attacks"it.) When this happens, Mast cells release histamine and cause an allergic reaction. We all know what that can be like!

By measuring a baseline IGE specific for peanut and then measuring it a year or 2 later, you can see if it has risen or decreased. Many tests after many years may help to determine a trend..and I assume can rise if you had an exposure. Hope that helps... [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

Almost forgot...our results:
Austin will be 2 in May. He had his first peanut exposure at 9 months old. It was anaphylactic. He is also anaphylactic to eggs. Has had 2 exposures that caused near anaphylaxis (not as bad as the peanut)- one when he was 10 months old and one when he was 1 year old. (until then he had consumed egg in the cooked form, baked in homemade cakes and in Gerber foods)
He was RAST'ed in may 2002 : peanut was 8.75 KU/L (1271% ref). egg white was 57.1 KU/L (3800% ref). egg yolk was 4.85 KU/L (769%ref). His total IgE was 520. normal is <53 FOR ALL AGES.
We got new results on his blood drawn last friday (10 months after the inital tests):
Peanut has dropped!! 3.36 KU/L (712%ref) and they did whole egg this time: 10.7 KU/L (1679% ref). His total IgE had dropped to 155.
To us this means even more caution on accidental exposure. I pray every day that we can deal with this allergy in a sane way. I am a firm believer in that God won't give you something he thinks you can't handle.
stay safe!

Thanks a lot Allison for explaining the IgE and giving your son's results to us!

I am not peanut allergic but my last IGE level was 950 (yes I am miserable from my allergies most of the time).
take care

I would like to thank everyone that has responded to this thread & encourage any one else to give us their numbers too.
I'm finding that apparently my son has a very high Peanut number but not so bad of an overall number - I'm thinking that probably means that although he is extremely allergic to peanuts, he doesn't seem to be allergic to many other things - and hopefully won't be later on either.

I can probably confuse everyone now! I don't know the TOTAL IGE yet, but will try to call on Monday to see if I can get the results. We had a CAP RAST done in June (I believe) of last year. His peanut was ZERO. He has experienced several anaphylactic reactions to peanut in the past, and even reacted to cross contamination. They food challenged and he definately did not pass!!! Two weeks later he had another reaction that was considered anaphylactic. He is also allergic to tree nuts but don't know the exact results of those.

Synthia- Thank you so much for the explaination on the numbers!! I've been coming to this site since June and I never knew what a "class 4" or whatever meant. My allergist never mentioned anything about those, just the numbers on the test. Anyway Autumn's results were:
26.0 KU/L
2707 % REF
So I guess that makes her a class 5?
Also, her allergist said he has actually had patients in the 7000's in the % REF. So I guess there's always someone worse off out there!
