Should I eliminate foods BEFORE allergy testing?

Answered on August 19, 2014

After a trial of going on a paleo diet and then off again, it became clear to me that I really do feel better with gluten and dairy removed from my diet. I never really felt "good," though-- and I haven't for almost as long as I can remember-- and I think I need to further investigate if the autoimmune protocol might be the trick. I'll also be seeing a new primary care doctor in a few days, and I'm finally going to start working to pin down a diagnosis and treatment for all my health issues (joint pain, moderately bad adult acne, infertility, headaches, anxiety, easily breakable fingernails, abnormally high testosterone levels, and worsening brain fog/memory loss).

My question-- what's the verdict on blood allergy testing? I did the skin prick test years ago with no results and want to go more in-depth this time, but would starting paleo or the AIP beforehand, thereby removing some potential allergens from my diet, throw off the results? Do I need to be currently eating gluten for a gluten allergy to show up?

I know the AIP might be my best chance of knowing how I react to different foods, but is love to see if alternative testing might reveal some answers for me. Ultimately, I'll end up doing AIP anyways, I just don't know when to start it.

Thanks for your help!

Thanks for your response, Linds! I just switched GPs and my new dr is (purportedly; haven't met her yet) of a more holistic mindset so I'm hoping she'll help me pin down a diagnosis or some allergies, but I do realize that I might not get any conclusive results. I guess I just want to legitimize my concerns with "hard evidence" rather than a self-diagnosis, but we'll see.

Allergy tests look for the antibodies that would be present if you were reacting to that certain food, so if you successfully eliminate it, the antibodies won't be there, and the test will be negative.

So, eat how you normally would before the test, so that if you produce antibodies, they will be present in the test, and then you can start your elimination from there.

I struggled with allergy testing/doctors for so long. I didn't know what types of tests to get or why and so I had string after string of test done and you know what? I never actually got a firm answer.

I'm not saying don't bother with these tests (maybe there is an underlying condition, I don't know), but for me it only added confusion. I was told I was allergic to beef, pork and eggs and that I had no issues with dairy or gluten on these tests but I knew for a fact through elimination diets and self experimentation that I felt SO much better when I didn't ingest those things. The test results varied year after year (I was allergic to dairy, oh no wait I'm not anymore but now I'm allergic to chicken) so I was constantly in flux and stressed about food. I suffered from all of your symptoms as well and the only thing that changed all of that for me was a 100% clean paleo/primal diet. All of my symptoms since going all in have reversed and or disappeared completely.

If your going to do the tests anyway I've heard that the foods need to be in your system for it to read on the tests but I can't say so with 100% certainty. It seems like that would make sense though.

Personally I don't think you need a blood test to 'see how you react to certain foods' -- you probably already know and if you don't try the two week test diet or FODMAPS or SDC. I hope you ind your answers whatever method you chose!

Good luck!

I just saw an Allergist at Stanford Hospital. We did the prick test on my back. Results showed I was allergic to Cow's Milk, Soy, Tomatoes,Peanuts, Tuna,Shrimp,Wheat and Corn. I've only eaten one of those in the past month or two and that was the Cow's Milk from CFM Whey Protein Isolate.

Except for the Wheat and Peanuts my numbers were pretty low on the Wheal/Flare scale. She said I probably wouldn't notice the side effects from eating those foods but my intestines and sinuses would.

I go back next month to talk to an Endocrinologist and her again to see if I'm allergic to more things and if I have an autoimmune disease. She started me on a eliminate diet, which I added nightshades to the list, except for the White Potato/Sweet potato since I'm not allergic to those.

My hubby just went through a whole host of food allergy testing, and was given instructions on exposing himself to certain allergens prior to collection.
