My DS was retested for peanuts, soy and overall IgE.

First test when he was 2 showed:

Peanut Class 6: >100
Soybean Class 2: .28

Second test when he was 4 showed:

Peanut Class 5: 84
Soybean Class 1: .69

Recent test when he is 6 showed:

Peanut Class 6: >100
Soybean Class 2: 1.46

Overall IgE was at 1560 when he was 4, now 845.

Question: Why would the Class go up once it was down. Does this mean he is being exposed and we don't know it?

Why would overall IgE go down, when specific IgE (peanut and soy) went up?

I meet again with the allergist at the end of month, I was hoping someone here could give me a little insight from experience.

I am afraid that the peanut went up again because of the exposure he is receiving at school. His school is not peanut free (pb is served everyday in lunchroom). Do you think this could be the cause?

Any insight is appreciated.

Why? Because.

Forget class. Forget scores. Score is higher than .35 therefore allergic and avoid.

Why? Age, perhaps, as one assumption is the scores go up until age X (I say 6 or 7....)

Jason thinks it's wind...

[i]I[/i] still maintain that it is the phase of the moon.... or something.

We saw the same pattern-- DD's numbers have (since she was 2) always been >100.... except for one RAST when she was about 4-5 when it was about 90.

Boy, were we [b]thrilled[/b] -- allergist burst that bubble in a hurry.... pointing out that it was absolutely MEANINGLESS because it was still so high. Last one, it was back up >100....

Oh well. Live and learn.

Doesn't change anything, now does it?

I understand...positive so avoid. I get that.

I think it is important for me to figure out why it is going up because if he is being constantly exposed at school, maybe there is something I can do or change to help. Before school, it was on a downward trend...now since he started kindergarten the trend is going upward.

My ds is going throught lots of testing right now, academic testing, adhd, and other because he just has not been feeling good and is really struggling in school. I am just starting to think that he does not feel very good because of the constant (even if minor) exposure in the school setting.

I can't forget class because it may be the key to figuring out what is going on with my DS. KWIM?

No its not [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

It doesnt go up IMO because of ingestion. It goes up 'just because'.

Caitlin never eats lobster, shrimp, etc etc etc...

Yet the scores go up....

Just because.

But thats my biased view YMMV of course...

Isn't is a strong possibility that if exposures are happening the numbers would go up, though?

When my ds was going though his "episode" last year when they couldn't figure out what "it" was, ONE (but not the only) thing that she said could rule out an ana reaction was the fact that his RAST numbers remained the same.

Now, granted, I am definately not saying that the reason that the numbers are going up are due to exposures. But don't they usually increase after exposures?

mistey: That is what I thought too. The number [b]may[/b] go up "just because." But isn't it also a possibility they go up for a reason? Especially since we have seen them go up since a change to my DS's environment has occurred.

I will have to discuss this further with the allergist.

I really hate to get involved in this one, since whenever I do participate in this debate about exposures, I get ripped to shreds by people who have a different opinion, but.......I totally agree with notnutty. I watched dd`s numbers go up up up until I eliminated all known airborne and contact situations, then I watched dd`s numbers for peanut go from 34 to 15 to 12. Might be coincidence, might not. Since I don`t know, I`ll keep doing what I am doing and hope to see it keep falling.

Carefulmom-don't hate to be involved in this discussion. I suspect part of the reason my DD's #s exploded was due to the fact that she had an aerosolized reaction, and possibly other less noticeable reactions. I think the allergist wouldn't say that it contributed for fear of causing me more guilt. I am curious and wouldn't have felt more guilty (no way I could have known they had a special peanut roasting machine set up for that day--we saw it, walked past, paid for our groceries and quickly left) because in this situation it was not an expected occurrence. I take precautions avoiding known risks for the fact that I suspect recurrent, minor exposure might contribute to IgE changes. It makes as much sense as anything else .

I would like to take all credit for my sons level going from 50 to 31(both are still class 5)....but in the year that happened(from age 5-6) he had many reactions, 2 when I should have used the Epipen.....so as much as I would like to think having no exposures would equal lower results....that just isn't the way it's working with my son!! I think every test is different, every result is different, every child is different...and on and on!

From the original poster, if the numbers had dropped from class 6 down to class 2, then shot back up...then I would be more skeptical, but your son went from 6 to 5 back to 6...it's still VERY high, in either class.
