Got my allergy results back.. Grasses/Rag weeds - .35 - Class 0. Maple, dog dander, cockroaches, birch, oak, elm, etc - .35 - Class 0. Egg white, peanut, wheat, walnut, codfish, milk, soybean, corn, shrimp, scallop, clam, kiwi - .35 - Class 0.

What does this mean? Well I know what it means, I'm not allergic to anything??! Does that mean I can eat all this stuff now?

I told the allergist I think it may be anxiety.

He wants me to keep a 2 week food diary..

He said there's 6 ways you can react to an allergy, and the one he did (blood) would rule out life threatning allergies...

Help me analyze this...

WOW!!! I think this means you can eat these things!!

I assume that what your results when you look at them say <0.35 . That's what mine say for the things I am not allergic to. But I also have my ige numbers. So for peanut it's 40, for pecan 14, for coconut 19, for almond 7--but each of these also has <0.35 and is "in range."

If you still have anxiety, you could get a skin prick test.

If you are really anxious about eating peanuts you could still avoid them but not be worried about people eating them around you and cross contamination.

I wish you well on this new journey of yours. I'm so happy you had the test. It helps us all (all who deal with FA).

Ohh i guess there is a "<" it almost looks like a ( lol.. that's what I thought it was. Of course the copy I got is all light and you can barely read it lol. Also, how do I know that they just didn't sum it up to all class 0's.. I wonder if they actually DID test me?! lol. I did give 2 tubes of blood ya know? Lol And I'm still paranoid...

Wow, that looks great!

I bet they did test all of those. It doesn't actually take much blood these days.

I'm sure the hardest thing is to pyschologically go from total avoidance to "never mind, move right along". It's probably akin to being told you don't need to wear clothes anymore. [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

If you are truly anxious, a skin test might make you feel better before actually eating some of it.

Our doc always does both(spt and caprast) when questioning a new food. My youngest scramed and pulled at her mouth when she ate a strawberry newton, so we tested(both tests) for strawberries....which both came back negative. But with her age(being just 1 1/2) he said to avoid still, she could become allergic or she could outgrow the reaction(tongue burning) with age. If you are still unsure/nervous, do the scratch test and you'll know for sure(negative caprast and negative scratch, with NO reaction history would say *all clear* in my book). Good luck!!!

Thank you! One question.. I do get seasonal allergies..like my "allergies" act up - wouldn't that have shown up on this lab?

On Sep 10, 2007

Congratulations. I'm in the same boat in that my tests are negative to certain allergens I'm not sure about and am not quite ready to believe or challenge yet.

I don't understand the part about blood tests ruling out LTFA. Do you mean that in your case, since your tests are negative, FA is ruled out, or do you mean some kind of blood test can distinguish between LTFA and non-LFTA? In my case, based on history, my doctor feels that what FA I have are unlikely to become LT/ana, but I'm not aware that it's any more than an educated guess that I hope is right.

The type of allergy that can cause life-threatening anaphylactic shock is called an "IgE-mediated" allergy. Three things can kill you with a food allergy: swollen airway, asthma or cardiac shock. All three of these are only triggered by IgE-mediated allergies, the kind that's tested for with a RAST test.

There are other kinds of allergies and food sensitivities but when a doctor talks about a food allergy, this is the kind he or she usually is citing.

There is a very small chance that you could be allergic to a protein that's not tested for on the IgE panel. Foods can potentially contain more than one allergenic protein. Some of the tests are better than others. That's why it takes all 3 criteria (negative RAST, negative scratch, negative food challenge) to truly eliminate an allergy.

Thank you booandbrimom. I understand about IgE mediated/non-IgE-mediated. My confusion seems to stem from a difference in wording. I've had a single apparently IgE reaction to something (presumed TN, but possibly not) that, while prolonged and uncomfortable, never approached anaphylaxis. Both my doctor and I recognize the possibility that a future reaction might change, but based on various factors, the doctor believes that's relatively unlikely for me and another physician agrees. They and I don't call my particular allergy a LTFA, while some on this board seem to prefer to use LTFA for any IgE mediated allergy, whether it's actually ever been ANA yet or not. I was thinking the orignal poster was implying there was a way to test if somebody who hadn't already had an ANA reaction was likely to have one in the future, but *that* doesn't exist yet. That's why I was confused.

My allergist says that, if RAST is negative, then do SPT. If SPT is negative, do a food challenge. You can get false negatives on RAST and SPT, so personally, I wouldn't feel comfortable saying no allergy until completing a food challenge.

I agree. That is exactly what our doctor says. Mommymegan would you have less anxiety eating the questionable foods first in your doctor's office? If so, see if that is possible. That is great news with your RAST testing! I'm sure they tested everything. DS just had RAST for all tree nuts, peanuts, soy, mangoes, etc.
