In my experience skin prick tests are pretty useless with a lot of those. Really, an elimination diet is the most useful tool in finding food intolerances.


I am a German citizen, married to a Canadian 29 years, four daughters, one son, seven granddaughters and four grandsons, with one more grandchild on the way in July 2009.

Intolerant to all lectins (including gluten), nightshades (potatoes, tomatoes, peppers, eggplant) and salicylates.

Asperger Syndrome, Tourette Syndrome, Addison's disease (adrenal insufficiency), hypothyroidism, fatigue syndrome, asthma

You can do an allergy test, but if it's an intolerance like celiac, you won't get a positive. My doctor recommended not getting an allergy test because sometimes certain foods just don't agree with certain people even though there isn't a true allergy. She recommended an elimination diet. I prefer the kind where you eliminate everything and then add things back one at a time, especially if you think there may be more than one food causing a problem. You could also do intolerance testing through enterolab, but they only test for gluten, soy, egg, dairy, yeast and not citrus, tomatoes, etc. I ended up going this route because dairy was the only thing I suspected and I was too impatient to do an elimination diet (not to mention I hate food journals with a passion!)

I'd say an allergy test is a good starting point because if it is an allergy at least you'll find out quickly. Good luck!


Gluten-Free since September 15, 2005.

Peanut-Free since July 2006.

You should look for an allergist that will guide you through an elimination diet after they do the skin prick testing. The skin testing will show any true allergies but not intolerances but it is helpful and a valid first step in the elimination diet process. I would be dead if I had not found an allergist who would help me with this. the elimination diet literally saved my life as I did not show up on blood test so I am a big fan of them when done properly.
