Positive For Gluten Sensitivity Why Do Blood Test For Celiac?

New here as my 6 year old just got her positive gluten sensitivity test back a few days ago. My quick question (that probably gets asked a lot her but I can't seem to find it) is, why do the blood test for celiac if the recommendation for GS is 100% gluten free anyway? I think I am going to do the blood test but I am not sure why I feel I need it done. Any thoughts? Am I not thinking of something obvious?

What test did she have done?

One reason to get it done it that children and young adults with celiac need special accomodations at school and college. Do not have the child go gluten free until after all testing is done as that will for sure cause a false negative.

She had the gluten sensitivity fecal test from Enterolab. I'm now thinking about doing the Anti-Tissue Transglutaminase Antibody fecal test for her. they already have her sample so it would be fairly easy. Would that be testing for the same antibodies as a blood test for celiac?

tTG IgG/IgA, Endomysial ABS IgA, Gladlin IgG/IgA.. all blood tests or entero does the fecal, if they come back positive most doctors want a biopsy to confirm.. some dont, but either way its the same diet knowing early is pretty great does your 6 year old have symptoms of celiac?

Will your Ped diagnose with the Enterolab testing or give you a note for school? If not do get her blood work done before you take her gluten free as she will need accomodations at school.

My pediatric GI discounted the enterolab testing. Getting a diagnosis can be helpful in little ones. It can also help them stay on the diet later when you aren't there to "police" them as teenagers.

I haven't asked her doc yet. She's been mostly gluten free for about 3 weeks now. I am so confused about what test to do next to make an accurate diagnosis. I REALLY do not want her to go through a biopsy at 6. I'm having Enterlab do the transglutaminase testing in hopes of getting some more answers. I guess what I am wonder is whether the IgA anti-glidan is a pretty good bet for celiac disease or is is mostly just a test for GS? Either way I will be keeping her on a gluten-free diet, I would just like to know. This article on this site says "That means that, if a patient is IgA positive, there is a 97% probability that they have celiac disease"...anyone have any thoughts on this?

That article refers to the results of serological (blood) testing. Most physicians do not recognize stool testing done by Enterolab. If she is already gluten free you have little chance of getting an accurate blood test, unfortunately. Not all doctors require a biopsy to diagnose - for some (and even for Dr. Fasano, the celiac "god", now) symptoms, positive blood test, positive gene test, and relief of symptoms by gluten free diet is enough for a confirmed diagnosis.

      My journey is it gluten or fiber?

      Is there a digestive enzyme that helps build a healthier gut? I see people taking them but not sure what really works

      Disaccharide deficient, confusing biopsy results, no blood test

      So the tTG-IGA at 28 is positive for celiac disease. There are some other medical conditions that can cause elevated tTG-IGA but this is unlikely. There are some people for whom the dairy protein casein can cause this but by far the most likely cause is celiac disease. Especially when your small bowel lining is "scalloped".

      hi, i want to say thank you to you and @trents . after 2 phone calls to my GI, her office called me back to tell me that a blood test was “unnecessary” and that we should “follow the gold standard” and since my biopsy did not indicate celiac, to follow the no dairy and sucraid diet. i luckily have expendable income and made an appt for the labcorp blood t...

      Thoughts? Non-endoscopic Celiac diagnosis in two year old

      Okay that is really good to know. So with that being positive and the other being high it makes sense she diagnosed her even without the endoscopy. So glad we caught it early. She had so many symptoms though that to me it was clear something was wrong. yeah I think we had better test us and the other kids as well.

      So the tTG-IGA at 28 is positive for celiac disease. There are some other medical conditions that can cause elevated tTG-IGA but this is unlikely. There are some people for whom the dairy protein casein can cause this but by far the most likely cause is celiac disease. Especially when your small bowel lining is "scalloped". Your Serum IGA 01 (aka, "total IGA") at 245 mg/dl is within normal range, indicating you are not IGA deficient. But I also think it would be wise to take your doctor's advice about the sucraid diet and avoiding dairy . . . at least until you experience healing and your gut has had a chance to heal, which can take around two years. After that, you can experiment with adding dairy back in and monitor symptoms. By the way, if you want the protein afforded by dairy but need to avoid casein, you can do so with whey protein powder. Whey is the other major protein in dairy.
