Unusual high levels

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.

      If your tTg-IgA was 28 and positive is at 3, you are nearly 10x over the positive marker, so the most likely explanation by far would be celiac disease. I also do not understand why your doctor would not want to run the blood test, which is the normal first step in the diagnosis process.

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

      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.

      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 test that day. i just got my results back and it indicates celiac disease i think 😭   im honestly happy bc now i KNOW and i can go gluten free. and i am SO MAD at this doctor for dismissing me for a simple blood test that wouldn’t have cost her anything !!!!!!!!!!! im sorry, im so emotional right now, i have been sick my whole life and never knew why, i feel so much better already   my results from labcorp:   Celiac Ab tTG TIgA w/Rflx Test Current Result and Flag Previous Result and Date Units Reference Interval t-Transglutaminase (tTG) IgA 01 28 High U/mL 0-3 Negative 0 - 3 Weak Positive 4 - 10 Positive >10 Tissue Transglutaminase (tTG) has been identified as the endomysial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten sensitive enteropathy. Immunoglobulin A, Qn, Serum 01 245 mg/dL 87-352
