Unusual high levels


Nielskii

Recommended Posts

Hi all! I hope you guys are doing well. A few weeks ago I started feeling a bit odd in the stomach with some minor cramps here and there. I decided to get my blood tested and I got a score of 573 on the tTG-IgA test! I get that some people have asymptomatic celiac disease but this seems very odd. Is there something I should about this?

Do you know the reference range for your test? It can be different depending on the lab that processed the test.

In the Europe the new protocol for making a celiac disease diagnosis in children is if their tTg-IgA (tissue transglutaminase IgA) levels are 10 times or above the positive level for celiac disease.

According to the latest research, if the blood test results are at certain high levels that range between 5-10 times the reference range for a positive celiac disease diagnosis, it may not be necessary to confirm the results using an endoscopy/biopsy:

There are other things that may cause elevated tTg-IgA levels, but in general a reaction to gluten is the culprit:

Check with your doctor to find out if he/she wants to refer you to a GI specialist for an endoscopy/biopsy to confirm the results of the blood antibody testing or whether or not the tTG-IGA levels are high enough to grant a celiac disease diagnosis without further tests being done. If further testing is expected, you need to refrain from starting a gluten free diet or you risk sabotaging the tests.

      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.
