Difference Between Ttg, Ema And Dgp?

Does anyone here know the difference between TTG, EMA and DGP blood tests? I know they all assess the extent of tissue antibodies but don't assess the body's reaction to gluten.

I don't know off hand, but I would highly recommend getting a copy of Dr. Peter Green's book - Celiac Disease a Hidden Epedemic, he covers all of these tests in that book in a way that is easy for the reader to understand.

Some of us know just fine off hand. She doesn't need to go buy a book!

TTG is an antibody against tissue transglutaminase, an enzyme involved in tissue repair. It is autoimmune and while the most common cause of anti-TTG is celiac, it can appear in rheumatoid arthritis, autoimmune liver disease, and inflammatory bowel disease as well. (There may be others; that list is off the top of my head.)

Anti-EMA is an autoantibody against endomysium, a type of connective tissue. Anti-EMA is HIGHLY specific for celiac disease.

DGP is an antibody against deamidated gliadin peptide (DGP), a fragment of gluten that has been processed in the intestine by TTG. It is not an autoantibody, but DGP is only produced in individuals with celiac so it's 100% specific for celiac disease.

Actually, that book should be required reading by everyone with a gluten problem. It is full of excellent information that would benefit many.

Then we wouldn't have people being scared by those who think there is gluten in vegetables! Or that everything is contaminated with gluten! :blink:

That's interesting that DGP is definitive for celiac. Can you reference that? The reason I ask is I had all the testing, and all the labs were normal except DGP, which was 4x the upper limit. I've had two separate biopsies and both were negative. I have mega-stomach issues with bloating and constipation. So, I've always wondered if I really am celiac due to that one test. Of course, the doctors tell me no because of the negative biopsies. I just began gluten-free yesterday.

    • Neutrogenia  on my face and whatever is on sale everywhere else
    • Hello Jules, Her tTg/Iga is very, very high and that will not occur from just the diabetes alone.  Since Type 1 and Celiac share the same genetics and can occur together, it would be great if she could have the complete Celiac panel run and not a partial. I do not understand the test for Immunoglobulin so cannot comment on that but her tTg is concerning for Celiac. With her symptoms, she should be fully screened for it, along with your other daughter who has Hashi's.  I also have Hashi's and that's another one that likes to pair with Celiac Disease. Tests in the full panel include: tTg/IgA and tTg/IgG- Since your daughter's tTg was sky high, the IgG version of testing usually done may not be needed. DGP/IgA- This tests for reaction to gluten in her diet. This is usually repeated with the tTg annually for dietary compliance, if she is diagnosed with Celiac. EMA- This test is usually not done unless the tTg is positive because it has to be done by a technician and not a machine and it is expensive. However, it is VERY important in a panel because if it is positive, then coupled with a positive tTg, pretty much is diagnostic for Celiac.  The GI will want to do a biopsy, which is usually indicated for kids or young adults. NO OTHER DISEASE WILL CAUSE A POSITIVE EMA BUT CELIAC DISEASE. Total IgA:  This is done to make sure a patient produces enough IgA antibody for testing purposes to be relevant but it will not be needed for your daughter.  Her tTg number proves she makes enough antibody. Good luck with testing and make sure she keeps eating gluten until all testing is completed!
    • I use Neutrogena and the Equate Walmart kind.  No gluten ingredients.  Celiacs don't need to worry about things they don't eat having gluten.
    • New here- would love some help. My daughter has type 1 diabetes. For the last 1-2 years she has been very irritable- major mood swings that can be activated over the smallest things. She has tested vitamin d deficient in the past- on a supplement now-has been recently complaining of pain in her legs nightly and having a hard time sleeping. Her hair which used to be very thick is now much thinner. She also has a very bloated belly with some diarrhea from time to time.    Her blood work was transglutaminase ttg iga >100 and immunoglobulin a 78 (range is 80 up)   she just tested positive for mono in the beginning of May  She also has an older sister with Hashimoto's    could this be anything other than celiac? thanks!         .
