Genetic Testing for celiac

My husband and I have been convinced to go through genetic testing (if not too expensive).  I have a few questions...

Do I ask the doctor's office or call our insurance about how much it will cost?

If both my husband and I have both genes, does that mean all of our children will also have both genes?  We already have 2 with celiac, so it seems our odds are high...  I wonder if we would need to bother getting the non-celiac kids tested if that was the case.

Is there any reason to test a person who has already been diagnosed with celiac?  (probably a stupid questions, but I'm asking anyway :) )

Thanks!

I'm not an expert by any means but I'll tell you our experience. My three year old was diagnosed based upon a very high ttg level and a positive genetic test. My husband got tested and has the gene but hasn't triggered celiac. My 7 year old has the gene but not celiac. My 5 year old doesn't have the gene. I haven't been tested because I figure it's coming from my husband's side, but I might still be tested just in case when the baby is old enough to be tested. I questioned our gi dr about the combination of genetic markers for the three of them with the gene. He said he would look over the genetic tests to see what their individual combinations could tell us. He did confirm my question about different genetic combinations raising or lowering the chance of triggering celiac. The advice we got was to monitor all immediate family members (blood tests every two years or sooner if showing signs of celiac). We chose genetic testing so we could potentially rule out having to test some kids continually. We just requested it from our regular dr and didn't contact insurance ahead of time. If someone is already diagnosed with celiac you wouldn't have to do genetic testing on them. Hope this helps a bit

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By trents · Posted

      I assume that you already know that genetic testing for celiac disease cannot be used to confirm a celiac diagnosis. About 40% of the general population has the genetic potential to develop celiac disease but only about 1% actually develop celiac disease. It can be used to rule out celiac disease with a high degree of confidence, however, in the case where the genetic testing is negative for the genes. Until and unless you are actually diagnosed with celiac disease I would not raise this as an issue with family. However, if you are diagnosed with celiac disease through blood antibody testing and/or endoscopy with positive biopsy I would suggest you encourage first degree relatives to also purse testing because there is a significant chance (somewhere betwee 10% and almost 50%, depending on which studies you reference) that they will also have or will develop active celiac disease. Often, there are symptoms are absent or very minor until damage to the small bowel lining or other body systems becomes significant so be prepared that they may blow you off. We call this "silent celiac disease".

      GI DX celiac despite neg serology and no biopsy

      By trents · Posted

      If you were off gluten for two months that would have been long enough to invalidate the celiac blood antibody testing. Many people make the same mistake. They experiment with the gluten free diet before seeking formal testing. Once you remove gluten from the diet the antibodies stop being produced and those that are already in circulation begin to be removed and often drop below detectable levels. To pursue valid testing for celiac disease you would need to resume gluten consumption equivalent to the amount found in 4-6 slices of wheat bread daily for at least two weeks, preferably longer. These are the most recent guidelines for the "gluten challenge". Without formal testing there is no way to distinguish between celiac disease and gluten sensitivity since their symptoms overlap. However, celiac disease is an autoimmune disorder that damages the small bowel lining, not true of gluten sensitivity. There is no test available for gluten sensitivity so celiac disease must first be ruled out. By the way, elevated liver enzymes was what led to my celiac diagnosis almost 25 years ago.

      Then it does not seem to me that a gluten-related disorder is at the heart of your problems, unless that is, you have refractory celiac disease. But you did not answer my question about how long you had been eating gluten free before you had the blood antibody test for celiac disease done.
