How Accurate Is Blood Testing

Hi everyone-

My doctor just sent me a blood lab with a full celiac panel. I'm not sure what else I can get tested for, but I figure that's the best place to start. I already have a thyroid problem... that I suspect I've had virtually most of my life but have only been medicated for four years... So I guess, according to many things I read and my doc, there is a slightly increased chance I could also have celiac disease.

My big question is, how many people are diagnosed or at least given a positive idea that they have celiac disease by blood tests? When i read this board I see that a lot of people have positive responses to following a gluten free diet but that many are not given officla diagnosis from blood work. While I realize that even if you get a positive diagnosis from blood work- you still have to go have a biopsy to officially see damage done to your body, what if you have silent celiac , or traditional symptoms of celiac that surface only on occasion, and negative blood work. I think it would be much more difficult to see a response to a gluten free diet that way, seeing as how you either dont have many or dont have traditional symptoms of celiac disease (that seem so horrrrrible.)

So just in general, how many people do respond to the bloodwork and does anything trigger a positive response in some people and negative response in others even if they are both suffering from celiac disease?

Thanks! :)

I was diagnosed by bloodwork alone. My doctor used a full panel and a gene test and didn't think it was necessary for anything else. The full panel has some very accurate tests in there for celiac.

Biopsies can only rule celiac in but not out. If you have beginning stages or have sporadic damage they can miss it.

Some people may find it harder to stick to the diet when they do not have symptoms...even if they have an official diagnosis but some people have no problem with it...it depends on the person but any celiac needs to stick with the diet 100% symptoms or not because damage will occur either way.

My 10 year old niece who has had "gastro issues" for 5 years was the first family member to get tested. Her blood work came back "equivocal" in only one area but her (brilliant) pediatric gastoenterologist decided that was enough to do a biopsy. The biopsy confirmed, without a doubt, that she had celiac. Since her diagnosis, there have been 3 others within 3 generations who have been diagnosed. Other family members were diagnosed through the celiac panel and genetic testing, AND gluten-free diet response. Each person had completely different symptoms or "issues" and no one thought they would have it. So, because of one family member's biopsy confirmation, the rest were able to avoid that step of the diagnosis.

      Not necessarily. The "Gluten Free" label means not more than 20ppm of gluten in the product which is often not enough for super sensitive celiacs. You would need to be looking for "Certified Gluten Free" (GFCO endorsed) which means no more than 10ppm of gluten. Having said that, "Gluten Free" doesn't mean that there will necessarily be more gluten than "Certified Gluten" in any given batch run. It just means there could be.

      I think it is wise to seek a second opinion from a GI doc and to go on a gluten free diet in the meantime. The GI doc may look at all the evidence, including the biopsy report, and conclude you don't need anything else to reach a dx of celiac disease and so, there would be no need for a gluten challenge. But if the GI doc does want to do more testing, you can worry about the gluten challenge at that time. But between now and the time of the appointment, if your symptoms improve on a gluten free diet, that is more evidence. Just keep in mind that if a gluten challenge is called for, the bare minimum challenge length is two weeks of the daily consumption of at least 10g of gluten, which is about the amount found in 4-6 slices of wheat bread. But, I would count on giving it four weeks to be sure.

      Are Bobresmill gluten free oats ok for sensitive celiacs?

      thank you both for the insights. i agree, im going to back off on dairy and try sucraid. thanks for the tip about protein powder, i will look for whey protein powder/drinks!   i don’t understand why my doctor refused to order it either. so i’ve decided i’m not going to her again, and i’m going to get a second opinion with a GI recommended to me by someone with celiac. unfortunately my first appointment isn’t until February 17th. do you think i should go gluten free now or wait until after i meet with the new doctor? i’m torn about what i should do, i dont know if she is going to want to repeat the endoscopy, and i know ill have to be eating gluten to have a positive biopsy. i could always do the gluten challenge on the other hand if she does want to repeat the biopsy.    thanks again, i appreciate the support here. i’ve learned a lot from these boards. i dont know anyone in real life with celiac.

      Let me suggest an adjustment to your terminology. "Celiac disease" and "gluten intolerance" are the same. The other gluten disorder you refer to is NCGS (Non Celiac Gluten Sensitivity) which is often referred to as being "gluten sensitive". Having said that, the reality is there is still much inconsistency in how people use these terms. Since celiac disease does damage to the small bowel lining it often results in nutritional deficiencies such as anemia. NCGS does not damage the small bowel lining so your history of anemia may suggest you have celiac disease as opposed to NCGS. But either way, a gluten-free diet is in order. NCGS can cause bodily damage in other ways, particularly to neurological systems.
