Allergy Skin Testing
Posted 24 February 2008 - 01:24 PM
Does anyone know how accurate skin testing is and if there are any other tests? It was quite a shock that he came back virtually negative to everything. I have similar symptoms and take year round allergy meds but I have never been tested for allergies. I unfortunately have not seen much an improvement with my asthma/allergies since going gluten-free but thankfully I am not too troubled by any severe symptoms. My brother seems to have worse symptoms. He did not go gluten-free specifically for nasal allergies but mostly because I tested positive for Celiac and because of some other problems he's been having.
So I guess my main questions are about the validity of skin testing for allergies and whether anyone has any other general advice on the diagnosis and/or treatment of environmental allergies.

Here is a good article:
My allergy symptoms cleared when I eliminated soy and now when I'm exposed to soy my sinuses puff right up. I know quite a few people who've had similar experiences.

I wonder the same thing. I had allergy skin testing done 2 years ago by an allergist/immunologist. He did over 40 skin pricks over 2 visits. Some foods, some environmental.
The result was that I was negative to all foods, positive for cats and highly positive for dust mites. It was interestiing because I have very strong seasonal allergies that require meds and at the time of the testing had eczema.
I asked him about blood testing for delayed allergies (sensitivites), but he felt they resulted in too many false positives.
From my own experience, the skin prick testing did not tell me which things caused my symptoms. I was given a prescription for Zyrtec and told to use allergy proof covers on my mattress and pillows (the latter helped immensely). He also had me do an elimination diet for my food sensitivities--I add this only because it turned out that legumes were causing my eczema. Since I cut them out 2 years ago, I have not had the eczema return--prior to this, I had it for 12 years.
Hope your brother gets things sorted out

I went to an allergist who specailizes in food allergies. He started with the skin pricks, and then did intradermal for anything I scored a 0 or 1 on the skin pricks. The way they explained it is the skin prick is a very small amount of the allergen, so if you react a lot to that, they dont want to inject any in you - but not reacting to the scratch itself doesnt mean you dont have an allergy.
I have had skin pricks, blood testing and intradermal (little shots under the skin). For me the intradermal was the most accurate.
I was tested for tons of foods and inhalants and reacted to almost everything ...
Off gluten and dairy (and tapioca ;-( ) since 11/07
A.L.C.A.T. test showed over 50 sensitive foods
Celiac panel came back negative.
Regular allergy testing reacted to every inhalant and all but 6 foods.
Slowly adding in foods, started w 19 and now have 25
