GPA IgG results

Hi all,

I was diagnosed last January and my TTG level is down to 4.  The range is 1-3.   My IgA test is within the normal range.  I don't know what IgA is.

My Glaiadin peptide AB IgG is way high, 86.  The top of the range is 19.  I'm waiting to hear back from my doctor but in the meantime, can someone tell me what IgG is?  Is this a food allergy number?  

Many thanks, Charlotte

Welcome to the forum! The article below is older, but still explains the tests well. It looks like you have two positive blood tests for celiac disease, so it is likely that will be your diagnosis. Your doctor may want to do an endoscopy and biopsy to confirm this, and to do that you should still be eating gluten daily for ~2 weeks before the biopsy.

Hi Scott, Thanks for getting back to me.  And thanks for sending the article.  Not sure I understand my results any better though.

I was diagnosed over a year ago with testing and an endoscopy.  I know I'm celiac.  This was the 5th follow up test to see if my gluten levels were dropping.  My TTG was down from the initial 27, to 5 last fall but I still had pain on the left side of my body.  My Primary care just thought I was still healing.  In Feb. I took a home test from Imaware and got higher numbers.  The TTG was 7.1 with a cutoff of 5.4U.  The IGG was 155.6U--the cutoff being 10.5U.  So that was worrisome.  So I saw a celiac specialist.  She ordered another round of testing.  That came up with the TTG at 4, cutoff at 3; IGG at 86, cutoff at--I think it was 19.  So two separate tests (although interpretive as they may be, are giving similarly high results for IGG).  And I still experience intestinal swelling and pain over my left hip.  I've no idea where the gluten is coming from, or if that's the problem. The specialist has mentioned it might be bad bacteria at this point.  I still have to test for that.  Not looking forward to doing the Quintron breath test since it requires a 24 hour prep.  Urg!

Thank you for the clarification, and you did mention in your initial post that you were already diagnosed, so my bad for not catching that.

There have been some studies that show that cow's milk can increase tTG levels in some people, so you may want to try eliminating dairy for a while to see if that helps to bring down your levels to normal, however, many people report it taking a year or more before those levels get back to normal.

Also, if you eat gluten-free oats you may want to exclude them as well, as ~9% of celiacs also have a reaction to them, which seems to be a separate intolerance.

Thanks Scott,

I eliminated all dairy, oats, and soy right after my diagnosis.  Funny enough I've just added dairy back in, (after the tests were taken however).  I really need the calcium.  So I'm drinking A2 milk which is delicious and doesn't seem to make anything any worse.  The specialist thought my diet may have been too restrictive.  I can't win.  I just feel exhausted.  Sorry to make you slog through all the details.  

Thanks for being there, Charlotte

No worries, and it could just take more time for you to heal. Hopefully you are taking vitamin & mineral supplements, many celiacs are deficient in many different nutrients, and this can also help with recovery. @Wheatwacked has posted here extensively on this topic, and this particular post may be helpful:

Hello!

What are you including in your diet?  Are you taking any medications that might contain gluten as a filler? 

Do you eat processed gluten free facsimile foods? 

Have you been checked for vitamin and mineral deficiencies?

Have you tried the Autoimmune Protocol diet?

Hi,  I don't take medications that have gluten.  My toothpaste etc. is gluten free.  I've had blood tested for deficiencies.  The only thing I can think of might be sliced cantaloupe from Whole Foods.  So I've stopped eating that.  Maybe their cutting boards have gluten?  

I don't know what the AP diet is.  

Many thanks

The AutoImmune Protocol Diet was developed by a doctor with Celiac Disease for herself and her Celiac children and others who have autoimmune diseases.

The AIP diet has been scientifically proven to promote healing in the body.

https://www.thepaleomom.com/start-here/the-autoimmune-protocol/

This diet has really helped me recover.  I was astounded at how quickly these dietary changes helped me feel better.  

I hope you look into it.  

Also IgG Dpg is another test for Celiac immune response used often in children and young adults.  The note worthy point is that your levels are going down over the past year.  It can take eighteen months to two years to heal from Celiac damage.  

By following the Autoimmune Protocol diet, a Paleo diet, you can further reduce inflammation and speed healing.

      Global Food Gluten Free Certification

      By Beverage · Posted

      I'd like to suggest nuts.com. They have a gluten-free section. I've never had an issue  and their nuts are super fresh tasting. I eat them every day as afternoon snack.  They label the packages as gluten-free, and more and more as Certified gluten-free. Here's their statement on gluten free:   Gluten-Free The FDA is the only regulatory agency that oversees all claims about food, including the use of gluten-free. A product can be labeled "gluten-free" if it contains less than 20 parts per million (ppm) of gluten. Other third-party certification programs have developed processes and standards for their “Certified Gluten-Free” labels. Some of our gluten-free products are certified by the Gluten-Free Food Program (GFFP), the most comprehensive certification program endorsed by the National Celiac Association. Our certified products contain less than five parts per million (ppm) of gluten.

      Guidance on next steps after the lab tests

      By Beverage · Posted

      My D was always low. It got better with gluten free diet, but was always below range or barely in range. I tried increasing D vitamins, found that K2 helps absorption of D. It improved a bit, yet remained on low end of ok range. After covid and bad flu years, i really wanted to get my D way up. We live in the Pacific Northwest, do lots outside 3/4 of the year, but sunshine is not abundant here in winter, when you are covered up anyway. I finally bought a vitamin D lamp. I doubt that the cheapie ones sold on places like Amazon are effective. Sperti makes one that uses florescent tubes, but I went with the Chroma LED Vitamin D lamp. They're not cheap, but I'm feeling a big difference. I haven't had my D levels checked yet since starting it this winter, but my hair has been growing in thicker like crazy, which is a sign of good D levels. Also, in spite of being around a few people who were ill, we haven't been sick with cold or flu...knock on wood. You will need more D than what is in your milk. Take a good high dose D3 and make sure it includes K2, or take a separate K2 at same time as D. I've been taking Life Extension Super K. Vitamin D needs acidic stomach to absorb, so don't take with anything that suppresses stomach acid. Get more sunshine 🌞 If all that doesn't get your D levels up, consider a vitamin D lamp, which I consider the best investment I ever made.

      Can food allergies like milk and soy flatten villi?

      By Matt13 · Posted

      Hi Knitty! Thanks for the reply! I can do squat but with alot of trouble and power. I will take all You advices in consideration and explore them further.... I am really lost in all of this...i mean villious atrophy can create soy, gluten, milk, casein....i mean what is left to eat? So when i had first EGD histology was MArsh 3b. After 1y on gluten free diet and smaller intake of milk (mainly i was eating and drinking lactose free products) histology was OK and Villi was normal...although marked as "please repeat EGD because one of the sample was not representative". But mi Gastro doc says it is OK and i can continue gluten free diet. So my questions are: 1.can i eat milk now or i am still trouble with casein/lactose...?  2. Can casein create villous atrophy in duodenum  because i need to repeat in some time new EGD due to semi faulty histology sample? Also BEST WISHES for NEW YEAR and Hollidays for everyone in this community!!!

      Bloodwork Help for my Teen

      By Sarah Marie · Posted

      Hello! I would appreciate help understanding my 17 year old daughter’s celiac panel.  Symptoms are general stomach discomfort, daily headaches (for years), fatigue. My husband is in process of being diagnosed as well.  test results: Demidiated Gliadin Abs, IgA - negative  Demediated Gliadin Abs, IgG - negative  tTG IGA - negative  endometrial antibody IgA - negative  tTG- igG - weak positive Immunoglobulin A, Qn, serum - *low* 72 (range is 87-352) vitamin D also very *low* at 21 (range 30-100) From what I’ve read the combination of deficiencies in vit d and immunoglobulin A plus weak positive tTG-IgG can indicate Celiac disease.  Thoughts?

      3 years with Celiac, now I appear fine.

      By Sharke · Posted

      Just the blood tests originally, which lead to the biopsy. The original blood tests and what they provided are lost, though I don't recall any hard evidence that it was related to celiac. They found a few polyps, but couldn't link them to celiac or gluten-intolerance. I have been under my own and my doctor's assumptions this whole time.
