Question about my RAST #\'s? I received my paperwork

I finally received my paperwork for my RAST test. I have a question. I was tested for Almond: <0.35
Peanut: <0.35
Pecan nut:<0.35
Sesame Seed:<0.35

The interpertation reads: <0.35 Absent/Undetectable Class 0

0.35-0.70 Low Level Class 1
& etc.

Does that mean my #'s are less than 0.35 & I'm not PA or TNA? I'm so frustrated because I know that I'm not making these reactions up & every time I've eaten nuts, I seem to trace back my reactions to PN or Pecans.
My worst reaction was after eating some triscuit crackers along with 4-6 pecans....bam 15 min. later my eyes are swelling & I had ithcy welts under my eyes. My eyelids had an itchy rash on them also. The swelling didn't stop & with Benadryl it took 7 days for my eyes to get back to normal.

Sorry I just had to vent. Thanks for any input or encouragement that can be passed my way.

I tend to think [i]history[/i] trumps RAST numbers. What did your allergist make of it? Maybe a different test will yield different results?

Hi. I think it means your #'s are low, but it doesn't mean you are not allergic. Just not as high as someone else. I still think if you are uncomfortable during a reaction stay away.
I tested low for peanuts but I know how I feel when I eat them and stay away. I feel like I'm choking on sand. I don't break out in hives from peanuts nor do I swell. Most people can't tell I'm reacting.
I tested higher for tree nuts (don't remember my #'s). I think I'm high for shellfish and seasonal 4+ for trees, grass and mold.
Trust how you feel.

thanks. You're right, I know how I feel. I just find it so perplexing to see #'s that say I'm not PA or TNA. I question about renewing my epi-pen script,purchasing a medical ID bracelet & etc. I don't want people to think I'm over reacting. My family is more concerned than I am. They get that I shouldn't share any utencil with them if they are eating nuts or nut butters. They make it a point to tell me not to kiss me if they've eaten nuts.
Thanks, I'm just venting.

What do those numbers mean?
They mean that you TEST negatively towards those allergens.
Doesnt mean squat IRT being allergic to something or not.
What others stated is true:
There are false positives and false negatives.. Testing is NOT 100% accurate for everyone.
Wise old person once said 'Reactions trump results'. Live by that.
If you eat peanuts, and have your throat close up, you're allergic. Even if the testing shows <.35

Thanks, Jason. I just have one question? what is HTH? I'm still learning all of the terms.

If your numbers are in that range, it means your body does not make IgE antibodies in response to nut/sesame antigens. By a doctor's definition of IgE allergy, you are not allergic.
However, there is another pathway for allergies - IgG. Ask your doctor about this if you really care to know. There are also food sensitivities which can be miserable, but are not considered allergies by a physician's definition.
The good news is that no IgE = no anaphylaxis risk.

I am far from an expert re: RAST scores - still new to me, but within the last month hasn't there been two people here who had a peanut challenge (I'm assuming because they had scores like yours) and failed?
Will you be having a food challenge?
