Doll,
I noticed you are allergic to pretty much everything. Is there a comprehensive test for food allergies, environmental allergies, environmental toxins, heavy metal toxicity? What type of test is best? I am in the US, so i dont know if there are different tests and standards compared to the Canadians. I really dont want to take multiple trips to the allergist, doctor etc. to get tested.
Please advise,
Jim
I had intradermal testing, which is a newer method of the old "skin prick" test. In this form of testing, they inject a small amount of the allergen just under the skin. I was tested for inhalants first, and then foods the next day. They use what is known as a "grid" system. If you are allergic to a substance, you will get what is called a "wheel" where that particular substance was injected. You may or may not get symptoms in addition to that, and if you do, they can range in severity from itchiness to shock (rare). I saw an allergist/ENT doctor for my testing. Overall, expect 2 days of testing. Inhalants are usually done first, foods second. The "wheels" on your arm from any allergic reactions will go away in a week or so. Perhaps a little sooner or longer. I still think "skin prick" tests are the most commonly used and are very reliable. I was orginally supposed to use the "skin prick" tests, I think. In fact, I am not 100% sure that the intradermal method was used for all of my testing. I might have to double check that! I maybe had the "skin prick" testing and got to two mixed up! I know my doctor offers both. I didn't want to watch my poor sore arm while it was tested.

There are also allergy tests that are done looking for antibodies in the blood. Heavy metal toxicity blood tests can be requested at most GP's offices, I would think, but you may have to convince the doctor to test you first.

I don't know much about chemical sensitivity, but I know some on this board have it. They may be able to tell you how they were tested. I am not sure if there is a "formal" test or not.
Some doctors use "elimination diets", but I don't think they are commonly used anymore to dx, with current testing methods.
I am on allergy shots now, but have just recently stopped. My allergies have been *killing* me, especially at night, and seem to have gotten worse after the shots. However, I am not sure if this is just coincidence. I am supposed to see my GP tomorrow. My ENT is in another city.
My major symptomatic allergies are the inhhalens (dust mites, moulds, etc.), wheat (on top of Celiac), and milk as far as I can tell. I was told to avoid wheat and milk 100%. Not a stretch.

I seem to tolerate potatoes, tomatoes, etc. without any noted symptoms, but I have been feeling so crappy lately (stuffy, sneezing, trouble breathing, escpecially at night, itchy, swollen eyes, random low blood sugars, dizziness, etc.) that I really have no idea if I'm reacting to my "minor" allergies or not. I'm supposed to go for further testing. I was originally supposed to go for RAST testing first. I don't know if it is more accurate to pinpoint what the "major" allergens I need to avoid are via RAST or not.
Hope this helped! PM me if needed.
Here is a link of how NOT to get tested for allergies (i.e. not reliable and quackery). I have heard of some people who say they can diagnose allergies by having a person put the substance under their tongue, and then check their arm strength! What? Um....no. Don't get scammed, see an MD familiar with allergies instead.
