Antibody Levels

I just got back from the gastroenterologist and am a bit confused. Before going gluten-free, my antibody levels were 53 when normal is 2 - 5 and anything above 18 is celiac. Needless to say I was a strong positive! About 6 weeks after going gluten-free I went for a second blood test and have finally gone for a follow up to get the results. My levels are the exact same! I am pretty sure I am completely gluten-free with my diet, because when I have been cc'd or glutneated boy do I know it! Are there any other reasons my antibody levels are the same? The doctor said I may have a very very sensitive immune system and that this level may be a plateau for me. Is this dangerous for my health? Any other explanations? I am a bit concerned right now and would love some feedback.

I'm questioning the short length of time you've been gluten free to be already testing for antibodies and expecting them to drop if you had significant damage at diagnosis. That being said, I really don't know what is recommended although my gastro suggested being retested in 6 months to a year.

I'm interested to see what others have to say about this, too...I've only been gluten free since April 9 and have not yet been retested.

I'm not sure I understand how long you've been gluten free. It sounds like you said you had one test, then 6 weeks of gluten free later you had another, and then you've had a 3rd test?? But how long from the 1st to the 3rd if that is the case? My dr also said to re-test in 6mos to a year. My first test before diagnosis I believe my antibodies were 88 (it's in my sig) and I just had it redone, and it was down to 9.

I would not be worried - I believe it takes a lot longer than 6 weeks for your antibodies to go down.

Wait at least six months - then if they're still high, that's when you can freak out.

Sorry for the confusion, I have only had two tests. The first one for diagnosis, and now a second. The second test was after 6 weeks going gluten-free, but then I had two wait 2 and a half months for a follow up appointment (my scheduling issues, not the doctor's...but now that I feel so great no need to rush back to the appointments, haha).

Thanks for your feedback. He is doing a second biopsy to make sure that is starting to look better. All I know is I feel so great these days.

A second biopsy after 4 months? that didn't leave you much time to heal. I'd be inclined to just get blood work done at 6 months and then, if there is no change, to consider a second biopsy at one year. (But I tend to wake up during such things and remember them as rather uncomfortable.) Especially since you feel good! If you still felt awful, that would be another matter.

I would get antibodies rechecked at 6 months and then if they are still elevated it might be appropriate to rebiopsy in case you are someone who has 'silent' celiac to make sure that damage is being repaired. IMHO rechecking at this point is too soon.

I had my antibody levels rechecked at 6 months and then again a little over a year later. I did have a repeat EGD and biopsy this April (1 1/2 years since last one) but I had the test for other reasons and since he was there he rebiopsied the small bowel to check progress. I my opinion I wouldn't rescope this soon. Wait for your six month blood work and then go from there.

My antibody levels were tested finally at near normal levels after 15 months from initial diagnosis. Definitely give it more time...your doc is too hasty.

Good to hear. I am actually going away for the next couple months and won't have the endo until I get back, so the second biopsy will be over 6 months after being gluten-free. It's already booked and I wasn't very affected by it last time, so mind as well keep the appointment. It is really great to hear that I don't need to get too worried yet.

I agree with everybody else, too soon to worry yet! What blood test are you talking about? tTG? My tTG level was 168 at first... 5 gluten free weeks later my doctor retested it only because I had to get some other bloodwork done anyway and it had dropped to 65. She did however make a point to say it's not normal to retest that quickly and that she wants to test again around 6 months gluten-free to see if it has dropped closer to more normal ranges since 65 is still too high but my body definitely didn't have enough time yet! It seems REALLY soon to have another EGD...

      Test uncertainty

      By MI-Hoosier · Posted

      Thanks again. My mom was diagnosed over 50 years ago with celiac so grew up watching her deal with the challenges of food. I have been tested a few times prior due to this but these results have me a bit stunned. I have a liver disease that has advanced rapidly with no symptoms and an allergy that could be a contributing factor that had no symptoms. I guess I’ll call it lucky my Dr ordered a rescreen of a liver ultrasound from 5 years ago that triggered this or I would likely have tripped into cirrhosis. It’s all pretty jarring.

      Does this definitely suggest Coeliac Disease?

      By Heather Hill · Posted

      Many thanks for your responses, much appreciated.  The tests did include tTg IgA and all the other markers mentioned.  I also had sufficient total IgA so if I'm reading the Mayo clinic thing correctly, I didn't really need the anti-deaminated gliadin marker? So, if I am reading the information correctly do I conclude that as all the other markers including tTg IgA and DGP IgG and tTg IgG and EMA IgA are all negative, then the positive result for the immune response to gliadin, on it's own, is more likely to suggest some other problem in the gut rather than Coeliac disease? Until I have a view from the medics (NHS UK) then I think I will concentrate on trying to lower chronic inflammation and mend leaky gut, using L glutamine and maybe collagen powder. Thank you for your help so far.  I will get back in touch once I have a response, which sadly can take quite a long time.   Kindest Heather Hill

      To put this in perspective, most recent pretest "gluten challenge" guidelines for those having already been eating reduced gluten or gluten free for a significant time period is the daily consumption of 10g of gluten (about the amount in 4-6 slices of wheat bread) for a minimum of two weeks leading up to the day of testing (antibody or biopsy). And I would certainly give it more than two weeks to ensure a valid test experience. Short answer: If it were me, yes, I would assume I have celiac disease and launch full bore into gluten-free eating. I think the tTG-IGA is reliable enough and your score is solid enough to make that a reasonable conclusion. Here is an article to help you get off to a good start. It's easy to achieve a reduced gluten free state but much more difficult to achieve consistency in truly gluten-free eating. Gluten is hidden in so many ways and found in so many food products where you would never expect to find it. For example, soy sauce and canned tomato soup (most canned soups, actually), pills, medications, health supplements. It can be disguised in terminology. And then there is the whole issue of cross contamination where foods that are naturally gluten free become contaminated with gluten incidentally in agricultural activities and manufacturing processes: Eating out at restaurants is a mine field for those with celiac disease because you don't know how food is handled back in the kitchen. Gluten free noodles boiled in the same water that was used for wheat noodles, eggs cooked on the same griddle that French toast was, etc.

      Thank you for the response and article. I was placed on the Mediterranean diet and been on that now for about 3 weeks. While not gluten free I am eating very little bread or anything with gluten ie a slice of whole wheat bread every couple days so assume that would cause issues now with a biopsy.  With the condition my liver is in I am unsure moving back to higher bread consumption is ideal.  In this scenario would my test results be enough to assume positive Celiac and just move forward gluten free?

      Welcome to the forum, @MI-Hoosier! You are operating on a misconception about your "mixed" test results. You only had two celiac disease diagnostic tests run out of six that could have been ordered if your doctor had opted for a complete celiac panel. It is perfectly normal to not test positive for all possible celiac disease diagnostic tests. That is why there is more than one test option. It is the same way with other diagnostic testing procedures for many or most other diseases. Generally, when diagnosing a condition, a number of different tests are run and a diagnosis is arrived at by looking at the total body of evidence. The tTG-IGA test is the centerpiece of celiac disease blood antibody testing and the one most commonly ordered by doctors. You were strongly positive for that test. It was not an unequivocal result, IMO.  Having said that, it is standard procedure to confirm a positive celiac disease blood antibody test result with an endoscopy/biopsy which is still considered the gold standard of celiac disease diagnosis. Had your tTG-IGA been 150 or greater, your doctor many have opted out of the endoscopy/biopsy. The absence of GI distress in the celiac disease population is very common. We call them "silent celiacs". That can change as damage to the lining of the small bowel worsens. Elevated liver enzymes/liver stress is very common in the celiac population. About 18% of celiacs experience it. I was one of them. Persistently elevated liver enzymes over a period of years in the absence of other typical causes such as hepatitis and alcohol abuse was what eventually led to my celiac disease diagnosis. But it took thirteen years to get that figured out. Within three months of going gluten free my liver enzymes were back into normal range. Thank goodness, there is more awareness these days about the many long fingers of celiac disease that are not found in the classic category of GI distress. Today, there have been over 200 symptoms/medical conditions identified as connected to celiac disease. It is critical that you not begin a gluten free diet until your endoscopy/biopsy of the small bowel is over. Doing so before that procedure will invalidate it because it will allow healing of the small bowel lining to begin. Here is a link to an article covering celiac disease blood antibody testing:
