Genetic Testing For Celiac - Questions

[marie06]

Hello, I have been gluten-free since 6/5 and 99% Casein free as well since then. I had an endoscopy done on 6/5 to see why I had been nauseous for almost 2 years and I asked the GI doc to do a biposy. He did 1, and said it was negative for Celiac (but note, only one sample was taken). 6 weeks later I went to be tested for food allergies and the doc did a Celiac blood test which also came back negative. HOWEVER, I have definitely seen a huge health improvement from going gluten-free and so I plan to stick with it. Now, my questions lie in the genetic testing that can be done for Celiac:

1) how accurate are these tests? I know that they can biopsy spots w/o damaged villi, and you could still have Celiac....and I know blood tests are not always accurate (esp when gluten-free for awhile). So what is the accuracy of the genetic testing?

2) is there a 'better' genetic test lab than another?

3) I am assuming a genetic marker will show up regardless of how long you have been gluten-free?

4) any other thoughts to share with regard to the above?

The reason I am concerned is mostly for my daughters sake. She is not showing any Celiac symptoms, but if she has a genetic marker for this, I think it would be good to know (OR if she DOESNT have the marker, I can stop worrying if she might get it). I call her my little "Carb-ovore" because she loves bread and pasta, would live on that if I let her. But she has no health issues that we know of and is fine on the growth chart, (actually 90%ile).

It would also be somewhat helpful for me to know if I am CELIAC or just Gluten Intolerant. Thanks in advance!

I used Enterolab and Kimball for genetic. This explains it well:
