How Does The Saliva Test Work?

Hi,

Ive seen on the board mention of a saliva test done by Diagnos-Techs, Inc. and they're located in Kent, Washington state ($27 US phone number 425 -251 -0596).

Can anyone tell me whether you need to be eating gluten for it to pick up celiac- like the blood tests? I want to test my toddler (I have celiac) but not with an intrusive blood test or endoscopy as she doesnt have any serious symptoms as yet (occaisional dioreah), and she is on a nearly gluten free diet as i only cook gluten free (but she has some gluten containing foods when she visits grandma etc) so i dont think she would have enough gluten to be worth the blood test.

thanks

My first diagnosis was by saliva test. There are many people who have high respect for those tests, but there are also many who don't think they mean much. Diagnos Tech believes that they are 90-100% accurate when the results are "positive'. I went on and did the Enterolab stool test after that and it DID confirm the original saliva results. So it proved totally valid in my case. According to Diagnos Tech, I believe you can be off gluten for a month or so and still get accurate results. The only exception would be if you have an insufficient Total Secretory IgA score. You should probably check that on the test as well so you will know if that's a problem. If it were me, I would maybe do the saliva test and then the Enterolab test. They work well to confirm each other and are both non-invasive and painless.

By the way, I would also test for eggs and soy and dairy while you are at it. You won't regret knowing.

      Accuracy of testing concerns

      By knitty kitty · Posted

      Welcome to the forum, @McKinleyWY, For a genetic test, you don't have to eat gluten, but this will only show if you have the genes necessary for the development of Celiac disease.  It will not show if you have active Celiac disease.   Eating gluten stimulates the production of antibodies against gluten which mistakenly attack our own bodies.  The antibodies are produced in the small intestines.  Three grams of gluten are enough to make you feel sick and ramp up anti-gluten antibody production and inflammation for two years afterwards.  However, TEN grams of gluten or more per day for two weeks is required to stimulate anti-gluten antibodies' production enough so that the anti-gluten antibodies move out of the intestines and into the bloodstream where they can be measured in blood tests.  This level of anti-gluten antibodies also causes measurable damage to the lining of the intestines as seen on biopsy samples taken during an endoscopy (the "gold standard" of Celiac diagnosis).   Since you have been experimenting with whole wheat bread in the past year or so, possibly getting cross contaminated in a mixed household, and your immune system is still so sensitized to gluten consumption, you may want to go ahead with the gluten challenge.   It can take two years absolutely gluten free for the immune system to quit reacting to gluten exposure.   Avoiding gluten most if the time, but then experimenting with whole wheat bread is a great way to keep your body in a state of inflammation and illness.  A diagnosis would help you stop playing Russian roulette with your and your children's health.

      Accuracy of testing concerns

      Welcome to the celiac.com community, @McKinleyWY! There currently is no testing for celiac disease that does not require you to have been consuming generous amounts of gluten (at least 10g daily, about the amount in 4-6 slices of wheat bread) for at least two weeks and, to be certain of accurate testing, longer than that. This applies to both phases of testing, the blood antibody tests and the endoscopy with biopsy.  There is the option of genetic testing to see if you have one or both of the two genes known to provide the potential to develop celiac disease. It is not really a diagnostic measure, however, as 30-40% of the general population has one or both of these genes whereas only about 1% of the general population actually develops celiac disease. But genetic testing is valuable as a rule out measure. If you don't have either of the genes, it is highly unlikely that you can have celiac disease. Having said all that, even if you don't have celiac disease you can have NCGS (Non Celiac Gluten Sensitivity) which shares many of the same symptoms as celiac disease but does not involve and autoimmune reaction that damages the lining of the small bowel as does celiac disease. Both conditions call for the complete elimination of gluten from the diet. I hope this brings some clarity to your questions.

      Accuracy of testing concerns

      Hello all, I was diagnosed at the age of 2 as being allergic to yeast.  All my life I have avoided bread and most products containing enriched flour as they  contain yeast (when making the man made vitamins to add back in to the flour).  Within the last year or so, we discovered that even whole wheat products bother me but strangely enough I can eat gluten free bread with yeast and have no reactions.  Obviously, we have come to believe the issue is gluten not yeast.  Times continues to reinforce this as we are transitioning to a gluten free home and family.  I become quite ill when I consume even the smallest amount of gluten. How will my not having consumed breads/yeast/gluten for the better part of decades impact a biopsy or blood work?  I would love to know if it is a gluten intolerance or a genetic issue for family members but unsure of the results given my history of limited gluten intake.   I appreciate the input from those who have gone before me in experience and knowledge. Thank you all!

      A little about me and my celiac disease

      I know what you mean. When I get glutened I have severe gut cramps and throw up for 2-3 hr. and then have diarrhea for another several hours. Avoid eating out if at all possible. It is the number one source of gluten contamination for us celiacs. When you are forced to eat out at a new restaurant that you are not sure is safe, try to order things that you can be sure will not get cross contaminated like a boiled egg, baked potatos, steamed vegies, fresh fruit. Yes, I know that doesn't sound as appetizing as pizza or a burger and fries but your health is at stake. I also realize that as a 14 year old you don't have a lot of control over where you eat out because you are tagging along with others or adults are paying for it. Do you have support from your parents concerning your need to eat gluten free? Do you believe they have a good understanding of the many places gluten can show up in the food supply?
