Question regarding blood results (IgA deficiency)

Hi celiac.com peeps! This is my first post on here — a quick question: based on my results below, should I be pursuing DGP IgA and IgG and EMA testing?

I have been dealing with GI problems for the past 6 months. My physician suspects potential celiac based on all of my symptoms, and referred me to a GI specialist who immediately dismissed celiac, did a colonoscopy and biopsy, and then told me nothing was wrong/he ruled everything out, and prescribed me Question (cholestyramine) to bind bile as a band aid fix. That hasn't helped and I am in the process of seeking a new GI specialist. 

Last week my physician ordered a celiac panel (TTG IgA Antibody, Antiendmysial Ab IgA, and total IgA) and a tTG-IgG test, and I just received my results today. (Pasted below.)

Component Standard Range Your Value Flag
Antiendmysial Ab IgA Negative Negative  
TTG IgA Antibody 0 - 3 U/mL <2  
Negative 0 - 3
Weak Positive 4 - 10
Positive >10
Tissue Transglutaminase (tTG) has been identified
as the endomysial antigen. Studies have demonstr-
ated that endomysial IgA antibodies have over 99%
specificity for gluten sensitive enteropathy.
Immunoglobulin A (IgA) 91 - 414 mg/dL 83 L
Component Standard Range Your Value Flag
TRANSGLUTAMINASE IGG 0 - 5 U/mL <2  
Negative 0 - 5
Weak Positive 6 - 9
Positive >9

Thank you for your help in advance! :-)

Kyle

EDIT: I am still eating gluten and have not yet tried an elimination diet.

Yes!  Pursue the other celiac tests.  But you are IGA deficient (score 83), so that should give you a false reading on the DGP IGA test as well.  I am not IGA deficient, but I tested positive on ONLY the DGP Iga tests and all the others were negative yet I had a Marsh Stage IIIB biopsy results.  

 

 What were the biopsy results?  How many samples were taken?  You should have or get copies of all your records.

The genet ic test I did only listed Anti-gliaden IgA. Mine was 11. Normal is less than 10. Anti-tissue Transglutaminase IgA is 6. normal is less than 10. I have HLA-DQB1*301 & HLA-DQB1*304. (Subtype 7,-)

From what I understand, I have 2 copies of the gene for celiac, meaning I'm predisposed to Celiac.  I'd appreciate any help interpreting it further.

It looks like you have a mild positive on the Anti-Gliadin IGA test.   A positive is a positive.  You only need one positive on the celiac blood panel.  The next step is obtaining biopsies via an endoscopy to confirm if you have celiac disease.   I suggest reasearching more on the University of Chicago's celiac website.

Just to clarify - the IgA is not a genetic test.  The HLA tests are the genetic ones of some type

Thanks so much for your help, cyclinglady. ? I am so appreciative of any advice coming my way during this pre-diagnosis period! I just went in for the DGP and EMA IgG blood draws yesterday — hoping they will indicate something for my next doctor's appointment.

Thank you. It's nice to hear from people going through the same thing.

I have been gluten-free for 3 years now, with the exception of cross  contamination here and there. Would my biopsies reveal anything at this point?

Hopefully, they would show healthy villi!  Experts normally just use the blood tests for diet compliance.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By trents · Posted

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  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.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By Xravith · Posted

      I'm very confused... My blood test came out negative, I checked all antibodies. I suppose my Total IgA levels are normal (132 mg/dl), so the test should be reliable. Still, I'm not relieved as I can't tolerate even a single biscuit. I need to talk to my doctor about whether a duodenal biopsy is necessary. But it is really possible to have intestinal damage despite having a seronegative results? I have really strong symptoms, and I don't want to keep skipping university lectures or being bedridden at home.

      They may want to also eliminate other possible causes for your symptoms/issues and are doing additional tests.  Here is info about blood tests for celiac disease--if positive an endoscopy where biopsies of your intestinal villi are taken to confirm is the typical follow up.

      New labs are now very elevated

      By Scott Adams · Posted

      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--and you are above that level. 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: Blood Test Alone Can Diagnose Celiac Disease in Most Children and Adults TGA-IgA at or Above Five Times Normal Limit in Kids Indicates Celiac Disease in Nearly All Cases No More Biopsies to Diagnose Celiac Disease in Children! May I ask why you've had so many past tTg-IgA tests done, and many of them seem to have been done 3 times during short time intervals?
