Recent Labcorp lab results show these results.

Endomysial Antibody IgA:  Negative

t-Transglutaminase (tTG):  <2 

Range for tTG lab is :  negative= 0-3, weak positive =4-10 ,  Positive >10

Immunoglobulin A, Qn  Serum :  417.  H
lab range 87-352 mg/dl

What is this telling me? Any recommendations?

Welcome to the forum, @RondaM!

These two tests are celiac antibody tests and they both look to be negative:

Endomysial Antibody IgA:  Negative

t-Transglutaminase (tTG):  <2

We commonly refer to the t-Transglutaminase (tTG) as tTG-IGA.

 

This one is what we commonly call "total IGA" and is on the high side: 

Immunoglobulin A, Qn  Serum :  417.  H

Total IGA is not an antibody test for celiac disease per se but the reason it is run is that if it is on the low side (i.e., you are "IGA deficient") it can cause the individual IGA tests that are designed to check for celiac disease per se to be falsely negative. This is not a problem in your case. I do not know that there are any particular health concerns connected to having a higher than normal total IGA.

Based only on these IGA tests it does not appear that you have celiac disease but it is unfortunate that only IGA tests were ordered. I would have been helpful to also include the DGP-IGG test. Some people who truly do have celiac disease just have immune systems that don't throw positives for IGA celiac antibody tests.

But here is an important question. Had you already begun limiting gluten in your diet before the blood draw for the testing was done? If so, it rendered the testing invalid.

Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.

Thank you for your feedback.  I was not eating gluten free at time the lab was taken.  Have been gluten free now for a week. How long might it take for symptoms to go away. Only issue I have is loose stool.

thanks again,,

If gluten is the problem or the only problem I should say, your stools should have normalized by now. But many in the gluten intolerant/gluten sensitive population are also dairy intolerant. Try eliminating dairy from your diet and see if the issues improve.

      Thank you so much for your response kitty that is helpful to hold in mind. I am also doing a review on lived experiences of coeliac disease so your blog would be incredibly valuable for me to review, please can I have the link to it?

      Virus, celiac disease or both?

      By knitty kitty · Posted

      @Shining My Light, Yes, celiac is spelled differently in Great Britain.  Yes, please do consider us as part of your support circle.   I had a serious Vitamin D deficiency, too.  I learned Vitamin D acts as a hormone when at levels between 78-100 nmol/L.  Mine was in the single digits.  I had been in declining health for years without answers.  I had developed hormone problems and clinical depression among other symptoms.  I corrected my Vitamin D deficiency with high doses to get my level up quickly.  Yes, it's safe.  Here's some studies done on high dose Vitamin D. https://pubmed.ncbi.nlm.nih.gov/34737019/ https://pubmed.ncbi.nlm.nih.gov/39125420/ https://pubmed.ncbi.nlm.nih.gov/35470105/ https://pubmed.ncbi.nlm.nih.gov/30611908/ My Vitamin D deficiency was just the tip of the deficiency iceberg.  I was deficient in the B vitamins, too.  Celiac Malabsorption affects all the vitamins and minerals, not just one.  Here are some articles about how the B vitamins and even Vitamin D help lower anxiety... https://pubmed.ncbi.nlm.nih.gov/33848753/ https://pubmed.ncbi.nlm.nih.gov/35156551/ https://pubmed.ncbi.nlm.nih.gov/35851507/ https://pubmed.ncbi.nlm.nih.gov/35851507/ https://pmc.ncbi.nlm.nih.gov/articles/PMC8533683/

      Virus, celiac disease or both?

      By Shining My Light · Posted

      @trents I’m pretty sure what I’m left with when separating celiac to other causes is my 10% being a virus. The one I had about 3 weeks before taking this TTG test. Everything I’ve read says type 1 diabetes, rheumatoid arthritis, hepatitis and some viruses are what could cause the elevation. The other blood tests I had I can compare things against.  I’m going to give your article a thorough read. My support in my circle is very small at the moment.  @knitty kitty I think before EGD I would like to do the DNA test. I’m going to start keeping a better journal also.  I’ve read a crazy amount of these “articles” - these two I’ve not seen. Some articles spell celiac differently. Thank you for sharing! I’m gonna dive into those.   I started seeing the functional medicine doctors from fluctuations in my hormones and major anxiety. Recently I realize it’s mostly health anxiety also so this is more challenging to depict real from imaginary thus all the research and the back and forth. I know anxiety to be a common symptom in perimenopause. I’ve fought it my whole life however. Likely due to lots of different trauma but seeing her was my last ditch effort to try something to avoid SSRIs, HRT, etc. She told me not to blame everything on my hormones when there could be an underlying problem, so she ran some tests to see if anything stood out. The TGG tests stood out.  I do find it very interesting now that I think about it that I don’t desire bread, pasta and pizza. Sometimes yes, but mostly no. I guess I didn’t give that much thought. Also didn’t realize that those foods do contain more gluten than the tortillas and cake/baked goods. About 3 months ago I started ordering meal kits to make dinner easier. I went back over the menus that I picked. I have probably had bread and pasta a hand full of times over the last couple months prior to having that blood test. We used to get pizza every Friday and stopped doing that also. I’m all fairness about 2 months leading up to these blood tests I had less gluten containing foods than I thought.    I’ve been praying for wisdom. Thankful to find some counsel from people who I believe have dove harder into this than most doctors have. Thanks for all the advice. It’s appreciated more than you know. 💕

      Waiting on biopsy after positive bloodwork, but also not really believing this is real

      @knitty kitty My whole family has migraines and I started getting them at age 19, so I'm not sure mine are related to gluten, although I do feel like obviously the more inflamed my whole system is, the more likely I am to suffer from more of these things.
