How much gluten to eat before taking the blood test?

Hello,
If someone has been off gluten for a while and then they slowly introduced it back to their diet and now they want to take the blood test, I read that it's possible if you don't have enough of the food in your body, the test could be wrong and say you don't have the disease when you actually do.  How long before the test and how much gluten products should one eat before the test? thanks for the info

The more gluten you eat, the better! Ask your doc to team blood testing or a biopsy with genetic testing to see what genes you're carrying. It's possible for people to have gluten issues that are not immediately apparent even with the biopsy being done. If you have the genes for either celiac or gluten sensitivity they're going to express themselves at some point. So if you're suspicious say off gluten. You'll be better off in the long run.

I disagree--it is better to eat plenty of gluten , if you can stand it, so that you can get an accurate blood test and know what you are really dealing with.

As far as i know, the only lab that identifies gluten sensitivity genes is enterolab--and there is a lot of questions as to how accurate their testing actually is--the guy who runs the lab also thinks that no on should drink milk.

Our family was part of a celiac study done through the University of california, Irvine, and in order to qualify for the test, you had to have 2 family members diagnosed with celiac with either a Ttg test or a biopsy. They would not accept anyone into the study who had been diagnosed by enterolab.

Dr Green, one of the, authorities on celiac, does acknowledge that some people have gluten sensitivity without having celiac.  They will feel lousy, but they will not get the intestinal damage that celiac causes.
