Food sensitivity blood test after avoiding allergens for 12 months

[Blaze422]

I was tested by an environmental allergist 12 months ago using injections on back (bubble tests) and was highly reactive to gluten,corn, dairy, sugar cane, cassein ,and somewhat to tomatoes and avocado.

I recently had bloodwork at a wellness center which included IgG blood work for food sensitivities. They were aware that I had been

avoiding those foods for the past year....and were very pleased at the findings appointment to tell me that I was no longer sensitive to those items and this was great news. 

Wrong! I call the source of this test (called  FIT TEST)...KBMO DIAGNOSTICS ...and they said I needed to be eating all  those foods for at least 2 weeks prior to testing.

    My question for y'all is if anyone knows a blood test that doesn't require me to play Russian roulette and probably feel like crap for 2 weeks to see if I can tolerate what I could tolerate a year ago.

If you are referring to non IGE-mediated food sensitivities, there are currently no tests available which can guarantee correct results. The validity of IGG tests as a measure of tolerance is questionable at best. Unfortunately, the only way to know for certain how you respond to those foods, is by eating them.

A food log is the only way to nail down sensitivities.  As mentioned there are currently no tests that can measure for them.  IgG mediated testing is a way to part people from their money and nothing more unfortunately as you have seen these aren't of use.

I tend to agree with the two previous posters.

The environmental allergist said you are sensitive to gluten. Have you been tested for celiac?  Now, according to the second blood test, you are no longer sensitive to any of those foods? 

Something is very wrong here.

If you've eliminated those foods, why not try them one at a time on different weeks to see how you feel? I'm sure you'll know fairly soon by how you feel. 

I am lactose intolerant, but I can eat hard cheeses and some Greek Yogurts. I can't tolerate any other dairy unless it's lactose free.

I am sensitive to soy, but I can tolerate small amounts depending where on the ingredient list they are. If soy is first, it's a deal breaker; if it's in the middle of the ingredients or further down the list, then I seem to not react. 

However, I would have never found out my tolerance levels for both dairy and soy unless I did a little experimentation.

Just want to make sure you were never diagnosed with Celiac?  Because, these tests have nothing to do with if a Celiac can eat gluten.  A Celiac cannot eat gluten and does not grow out of it.
