High Gliadin, Low tGG results

Hello,

I just discovered this forum and it seems I am in very good company when it comes to being confused by Celiac bloodwork.

Here are my recent results with info and request for advice at the end:

*IGA = 399.   Standard range: 47-310

Tgg/igg = 2.  Standard range < 6

Tgg/iga = <1.  Standard range < 4

**Gliadin iba = 27 > 20 antibody detected

Gliadin igg = 2. Standard range < 20

Background: Dr suggested IBS diagnosis 3 years ago and I settled into a gluten free diet. My symptoms decreased/resolved so I've stuck with a GFD since then. I do "cheat" occasionally and did consume gluten 2-3 times in the weeks leading up to bloodwork (pandemic teaching is stressfull!). Dr suggested the celiac panel after routine bloodwork showed iron deficient anemia and low B12, as well as a return of some digestive issues that match celiac symptoms.

Questions: **is the single positive antibody test an indicator for Celiac? Could my GFD history with recent "cheats" result in a negative tGG with positive Gliadin? Any advice for how to proceed with my Dr?

*I found an article that correlated high IGA numbers with recent covid vaccination so I'm thinking that may be the answer to the first result.

Thank you in advance for any insight!

Most definitely! Your doctor should have advised you to go back on gluten for about two months before testing. The guidelines are daily consumption of gluten equivalent to two slices of wheat bread for 6-8 weeks before serum antibody testing and at least 2 weeks before the endoscopy/biopsy. On this forum we frequently have people post with your same experience. Fact is, most general practitioners are not very knowledgeable about gluten-related diseases and often give poor council.

Thank you for your response!

I was not expecting a celiac test that day and was pretty disappointed when researching the test after the fact. Had I known the protocol I would have certainly delayed the bloodwork. 

Is it worth doing a gluten challenge and redoing the bloodwork or is the gliadin result, as it is, enough to request moving forward?

You stated that you experienced some improvement in your symptoms when you began to remove gluten from your diet so that in itself strongly suggests you have either celiac disease or gluten sensitivity. If you were to get serious about eliminating gluten from your diet you would likely experience even more improvement. Some people need the official diagnosis of celiac disease in order to stay on track with their gluten free eating resolve. Without it, it's easier to rationalize it as coincidence or some other cause and keep cheating.

      Anyone else with very high HDL?

      I have taken thiamine on and off (just not at this exact moment), and I’m not sure it's made any difference. Yes, I almost always “fast” (12 hours NPO) for blood tests, as do a great many other Americans, so I tend to think that’s not it. All I can say is that the mystery continues. I could do some speculating here…well, heck, let me go ahead and specu...

      Anyone else with very high HDL?

      Well, I have the opposite problem. My LDL has been moderately high for years. I eat healthy and exercise regularly but can't seem to move that meter. I used to be on a statin (and my doctors want me to go back on one) and it brought both HDL and LDL down but the ratios never changed. I think a lot of that cholesterol stuff is just baked into the genes.

      Celiac Disease and Mild Chronic Gastritis

      Welcome to the forum, @Tyoung! I would assume for the time being that the mild gastritis and the celiac disease are connected and that once you get a good handle on gluten free eating and experience significant healing in the lining of your duodenum, you will also see improvement in the gastritis as well. Gastritis is more often than not an accompanying...

      Celiac Disease and Mild Chronic Gastritis

      Hello! I was recently diagnosed with celiacs and mild chronic gastritis was noted on my EGD as well. My GI did not even bring up the gastritis and when I asked she brushed it off. I really want to heal my gut completely not just from celiacs but also the gastritis. Did anyone else have this at diagnosis? Were you able to treat it? Was it associated with celiacs...

      Anyone else with very high HDL?

      By plumbago · Posted

      I have taken thiamine on and off (just not at this exact moment), and I’m not sure it's made any difference. Yes, I almost always “fast” (12 hours NPO) for blood tests, as do a great many other Americans, so I tend to think that’s not it. All I can say is that the mystery continues. I could do some speculating here…well, heck, let me go ahead and speculate now: The lab ranges we all see on our reports are more or less the averages of Americans who have had those blood tests. Now, it’s up to you and me whether or not to think of the average American as healthy. I can make arguments both ways, more often than not, on the negative. My point here is that maybe the current range of HDL is somewhat skewed (ie, low), and maybe just maybe my super high (plus 100s) HDL results are not something to worry about; the range just needs updating. Why do I say this? Because pre-celiac disease diagnosis, my HDL values were in the normal range, but post celiac disease diagnosis, my HDL levels are way above average. See where I’m going? My trusty guidebook on celiac disease, Recognizing Celiac Disease by Cleo Libonati, RN, BSN, says that HDL increases after being on the gluten free diet. Or can increase, I guess. Then again, it could be something else. ¯\_(ツ)_/¯ In thinking of going to a cardiologist, I sort of fear that he/she will be dismissive of a link to celiac disease, treated celiac disease, and would not therefore be considering all possibilities. @trents I'm sorry you've been diligently working on your numbers to no effect. That must be frustrating. LDL is a world that is far better understood than HDL, so for you there's maybe less "mystery." Familial hypercholesterolemia is for sure something that can be tested. Outside of that, you're right, genetics can determine a general pattern.
