PA . . . NOT--got test results back. Am not believing it.

I had an ImmunoCap test done before Christmas because I suspected a shellfish allergy, but peanut was included. I was very happy about this because I had only had a scratch test done about 4 years ago for peanut and I was a 1 (I thought I was a 2 and may have mentioned that here but having looked recently, I was a 1). Considering several reactions over the past few months--including one to a may contain Lindt chocolate bar (no blatant nuts) this past Saturday--I truly thought that my PA was getting worse. I fully expected my ige number to reflect that.

I've been pretty descriptive on this board about reactions--99% limited to GI.

So I was shocked today when my doctor called me and he told me that I was negative to peanuts. Negative.

Utterly shocked.

He's sending me the results, and I look forward to that, but he was clear about this. We talked about it for a bit today. I told him again about some of the reactions (and we'd talked a few weeks ago, which is why he included a nut panel).

I did turn out to be a Class 3 for shrimp and Class 2 for crab and lobster. I'll truly miss shrimp. I'm completely surprised to learn I'm a Class 2 for Sesame.
And I don't actually believe that, to tell you the truth. I don't react to it. I enjoy hummus. I enjoy multi grain bread on a regular basis.

I think the lab screwed up and mixed up my peanut and sesame numbers.

That has to be it. I can tell you at least 8 specific times I've had reactions to peanut in addition to others that I can't specifically remember. And 0 times I've reacted to sesame.

Okay--about half an hour ago I poked my finger in the jar of sesame seeds in the pantry and ingested some. I've got benadyl and an epi at the ready. But I don't believe I'm allergic to sesame seeds. I just don't.

Did I have "sympathetic PA" or a "sympathetic sensativity" because of DS? Hmmm. I don't think so. I remember being sick most of the night on a business trip to LA after eating PBJ. And being sick after eating Thai food that I loved when I knew I wasn't going to see DS.

And there have been just too many times I've had something and have reacted. Like a couple of months ago at work when I had pecans and had a reaction and had to leave to buy benadryl. They had to be xcontaminated. I don't react to the "safe" pecans we have at home.


Well, I had to share the news here.

You assume one thing and it turns out not to be the case.

Or the lab screwed up. I'm still going on that assumption.

I'm the same with sesame allergy, I'm a class II but I've never ever had a reaction...in large doses I've had sesame chicken and sesame bagels. Nothing. I also pushed a Class III for peas...which makes sense b/c of my peanut score (Class V). But, I love peas, pea pods, snow peas and have never ever had a reaction.

My allergist told me that sometimes the Class # doesn't really indicate how severe of a reaction one will have. I'm a Class III for shrimp, and from cross-contam. I've been sick in the bathroom to the point I though I had food poisoning. Then, nada for peas or sesame.

Yay! on the peanut allergy though! Are you going to try a challenge? You might be onto something with the psychosomatic/empathetic reaction though...how about you try a blind challenge?

Thanks Adrienne. So do you avoid sesame now?

I have not reacted a bit and DH roasted some sesame seeds, and I've eaten about 2 tbs of them and nothing. Not even a sniffle.

Edited to add--No I did not do this; it would be foolish: Yes, I am planning on doing a peanut challenge--but on my own on a day when I know DH will be home in the evening with DS and I can do a thorough cleansing before seeing DS (involves lots of toothbrushing--throwing away the toothbrush--listerine--lipbrushing, etc.).

I don't know how to do a blind PB challenge. I know what peanuts taste like. I can tell sunbutter from peanutbutter.

If I don't react from the sesame seeds and I do react from the PB--when I'm kind of expecting not to at this point--then I'll ask for a retest of a peanut panel only. But first I'll ask my doctor to talk to the lab to see if they've had anyone else report a suspected screw up.

Anyone had the lab mess up? Goodness--then what else could they have messed up?

In terms of the PA, if I remember properly your symptoms are primarily GI, yes? Then perhaps it's not an IgE mediated allergy. I don't know for sure, but I don't think scratch or RAST tests measure non-IgE reactions.

There is another type of reaction who's name I can't recall that primarily affects the gut. Perhaps that's it?

Good luck,

Sorry to hear about your new allergies. I wouldn't be happy about the shrimp either!

I don't know if the lab messed up or not, but it is possible to have false positives and negatives.

You are making me kind of nervous doing a peanut challenge at home though. I'm sure you could do it at the doctor's if not the hospital. Please be careful!

I think it may be IgG mediated reactions that are primarily gut - might be worth some research...

nope - I don't avoid sesame, or peas. My allergist said that if I haven't been having the remotest reaction, then not to worry about it, but to keep an eye out if I do start to feel sick after eating them.

That being said, I probably won't be having any more sesame laden items (like sesame bagels or sesame chicken) or use sesame oil in cooking anymore. I'd hate for it to get worse.

I think I'm going to go in for a skin prick test, since as someone else pointed out in the other thread, that the IgE and skin prick can each catch different aspects of an allergy.

Thanks y'all. From what I've read, IgG mediated reactions typically are gut--which mine are (with the exception of the reaction that I think was a xcontam from pecan bread). But if I've read correctly, they're also typically delayed a few hours to a few days. Lately my peanut reactions have been after a 20-30 minutes.

If I remember what my doctor said, he suggested that what I have may be an intolerance and what the ImmunoCap results really tell us is whether I can expect to have an anaphylactic reaction or not. He said based on the results, I shouldn't. And he assumes that I'm going to avoid peanuts anyway because of DS. And he's right, of course.

It's just that Saturday's reaction scared me. And if I thought I had to be more careful in what **I** order when I go out to eat, then I would, you know?

All the reactions that I think have been PA related have been GI and quick--getting rid of things quick. But this past Saturday's, and that one was like my shellfish reactions (which I know are real--found out I'm Class 3 on shrimp). It felt like that. And I had to keep medicating like I do with shellfish. Maybe it wasn't the "may contain" Lindt chocolate. But I don't know what else it would have been.

Momma2boys--point taken. I'll talk with my doctor about it.

Okay--enough navel gazing. Thanks. This has been just too much of a day. Being told I'm not PA. And getting the confirmation I am shellfish allergic. It was just a bit much--and I've been all over the board with it, I know. I've known inside I was shellfish allergic (SFA???) and reacted to Xcontaminated fries a few weeks ago. But then to realize finally that you can never ever have a certain food again. Never. And that you aren't PA when you really, really think you are (and not having PB didn't bother me, but shrimp . . . .). It just seemed a bit much.
