Wrong Tests Or Same Thing?

So I have been seeing people mention that the tests for Celiac should be:

Anti-gliadin (AGA) IgA

Anti-gliadin (AGA) IgG

Anti-Endomysial (EMA) IgA

Anti Tissue Transglutaminase (tTG) IgA

Deamidated Gliagin Peptide (DGP) IgA and IgG

Total Serum IgA

So, my son had his bloodwork done. His tests were:

Endomysial Antibody IgA

Tissue Transglutaminase IgA

GLIADIN IgG

GLIADIN IgA

Total Serum IgA

Are they the same thing if his tests do not say 'Anti'? His bloodwork was negative for Celiac, but his allergy tests came back with low allergies for 6 different foods (including wheat). He has also had a great response since going gluten-free. I was just wondering if the right tests were done to rule out Celiac.

Same tests, different shorthand. The "anti" is short for antibodies, as in it is measuring the body's response to certain proteins.

While celiac cannot be ruled out 100% because a certain percentage of tests are false negatives, it is less likely.... however.....

What is important is his response to the gluten free diet, if it works, keep doing it !

But they left out the Deamidated Gliadin Peptide (DGP) IgA and IgG test which as I understand it is specific for celiac disease & that's why it was recently added to the full panel & is supposed to be more spot on. Someone correct me if I'm wrong about that please.

Are blood tests good for food allergies? My allergist said they can come back with false positives and that's why he recommends the skin test. I am having the skin test next week. My primary wanted to order blood work but I think I may just do the skin test.

Thank you! I know that even with a negative test Celiac cannot be ruled out completely. The nice thing is that, even with low allergies, at least I have that diagnosis for him for school, or whatever he might need it for. Since he has responded so well to the gluten-free diet, we will just stick with it and I won't have to subject him to biopsies, etc. ;)

      Celiac and dermatitis herpetiformis has taken Me from Me

      Two months ago, I started taking Dupixent for dermatitis herpetiformis and it has completely cleared it up. I can't believe it! I have had a terrible painful, intensely itchy rash for over a year despite going fully gluten-free. See if your doctor will prescribe Dupixent. It can be expensive but I am getting it free. When the dermatitis herpetiformis was...

      New Celiac Mama in My 30s

      @tiffanygosci, Thiamine deficiency is a thing in pregnancy for "normal" people, so it's exponentially more important for those with celiac disease and malabsorption issues. I studied nutrition before earning a degree in Microbiology because I was curious what the vitamins were doing inside the body. See my blog. Click on my name to go to my page...

      Thank you for sharing all of this, Knitty Kitty! I did just want someone to share some commonality with. I did not know This one Deficiency was a thing and that it's common for Celiac Disease. It makes sense since this is a disorder that causes malabsorption. I will have to keep this in mind for my next appointments. You also just spurred me on to make that...

      Outgrow celiac?

      I think your initial idea, eat gluten and be tested, was excellent. Now you have fear of that testing, but isn’t there also a fear each time you eat gluten that you’re injuring your body? Possibly affecting future fertility, bone health and more? Wouldn’t it be better to know for sure one way or the other? If you test negative, then you celebrate and g...

      Outgrow celiac?

      @Riley., Welcome to the forum, but don't do it! Don't continue to eat gluten! The health problems that will come if you continue to eat gluten are not worth it. Problems may not show up for years, but the constant inflammation and nutritional losses will manifest eventually. There's many of us oldsters on the forum who wish they'd been diagnosed...

      Celiac and dermatitis herpetiformis has taken Me from Me

      By SusanJ · Posted

      Two months ago, I started taking Dupixent for dermatitis herpetiformis and it has completely cleared it up. I can't believe it! I have had a terrible painful, intensely itchy rash for over a year despite going fully gluten-free. See if your doctor will prescribe Dupixent. It can be expensive but I am getting it free. When the dermatitis herpetiformis was bad I could not do anything. I just lay in bed covered in ice packs to ease the pain/itching and using way too Clobetasol. Dapsone is also very good for dermatitis herpetiformis (and it is generic). It helped me and the results were immediate but it gave me severe anemia so the Dupixent is better for me. Not sure if it works for everyone. I cannot help with the cause of your stress but from experience I am sure the severe stress is making the celiac and dermatitis herpetiformis worse. Very difficult for you with having children to care for and you being so sick. Would this man be willing to see a family therapist with you? He may be angry at you or imagine that your illness is a psychosomatic excuse not to take care of him. A therapist might help even if he won't go with you. Also do you have any family that you could move in with (with the kids) for a short time to get away? A break may be good for you both.

There's a lot of information online but I do need to see a professional. There is too much to juggle on my own with this condition.<3

      I think your initial idea, eat gluten and be tested, was excellent. Now you have fear of that testing, but isn’t there also a fear each time you eat gluten that you’re injuring your body? Possibly affecting future fertility, bone health and more? Wouldn’t it be better to know for sure one way or the other? If you test negative, then you celebrate and get tested occasionally to make sure the tests don’t turn positive again. If you test positive, of course the recommendation from me and others is to stop gluten entirely.  But if you’re unable to convince yourself to do that, could a positive test at least convince you to minimize your gluten consumption?  Immune reactions are generally what is called dose response, the bigger the dose, the bigger the response (in this case, damage to your intestines and body). So while I am NOT saying you should eat any gluten with a positive test, the less the better.
