Hello, I am new here. I was just tested after being gluten free for 3 months. I do feel much improvement. I'm not sure why the doctor tested me after being gluten free but here are my results:

Gliadin Ab IgA SERUM 4 < i> Units 0-19
Tissue Transglutaminase Ab IgA SERUM <2 < i> U/mL 0-3
IgA SERUM 212 mg/dL 91-414

 

My symptoms were mainly fatigue, brain fog, hand swelling, foot pain, back pain, abdominal pain and gas, constipation, menstrual irregularities. My symptoms have been wearing off and the few times I ate gluten my symptoms were just awful.
 

Also, my gliadin iga was 4 so does that mean it is still positive?

I 've been gluten free for 3 months but the doctor tested my anyway since I have still had some mild symptoms. My symptoms were very bad before going gluten free(I chose to do it without consulting the doctor, bad, I know)
Is the gliadin iga positive or negative?

If you were gluten free for three months these tests are almost useless, unfortunately. 

 

Those tests are pretty much negative.

Hopefully, someone can interpret it. I am stumped!

So, Fenrir, are you reading "i" (which is 4 in this case) should be greater than 19?

looks to me like the normal range is 0-19, her result is 4. the "i" looks like a product of copy and pasting from a webpage.

That's what I read too; looks all negative. tTG normal range is 0-3 and AGA (anti-gliadin antibodies) range was 0-19.

 

The SGA tests are not very good, and few doctors use them any more.  Look on page 12 of this report: Open Original Shared Link You can see the sensitivity can be as low as 17% for one AGA test, which means that 83% of celiacs would be missed.  It's specificity (perecntage of positives caused by celiac disease) is lower than the other tests too.

 

The deaminated gliadin peptides (DGP) tests have replaced them, and they are usually used for testing for gluten-free compliance.  Unfortunately, you have been gluten-free for 3 months so I would expect your AGA  (and DGP) tests to be negative.  Sometimes the tTG tests can linger high for a few months, but there is no way of knowing if you are one of those people bar doing a gluten challenge for 8-12 weeks, testing, and then going gluten-free for 3 months and testing again. 

 

The only way to know if you have celiac disease is to do the gluten challenge and retest withe the newer tests (DGP IgA and IgG, and tTG IgA and IgG). :(

      Sainsbury's Free From White Sliced Bread - Now Egg Free - Completely Ruined It

      @HAUS, I was at an event in the UK a few years back. I remember ringing the restaurant ahead to inquire about the gluten free options. All I wanted was a few gluten free sandwiches, which they provided and they were delicious. The gluten-free bread they used was Warbutons white bread and I remember mentioning it on this site before. No harm in trying...

      Sainsbury's Free From White Sliced Bread - Now Egg Free - Completely Ruined It

      In the U.S., most regular wheat breads are required to be enriched with certain B-vitamins and iron, but gluten-free breads are not required to be. Since many gluten-free products are not enriched, we usually encourage people with celiac disease to consider a multivitamin. In the early 1900s, refined white flour replaced whole grains, and people began...

      Keep in mind that there are drawbacks to a formal diagnosis, for example more expensive life and private health insurance, as well as possibly needing to disclose it on job applications. Normally I am in favor of the formal diagnosis process, but if you've already figured out that you can't tolerate gluten and will likely stay gluten-free anyway, I wanted...

All I wanted was a few gluten free sandwiches, which they provided and they were delicious. The gluten-free bread they used was Warbutons white bread and I remember mentioning it on this site before. No harm in trying it once. It's fortified with Calcium and Iron. https://www.warburtonsglutenfree.com/warbs_products/white-loaf/ The only other gluten-free bread that I've come across that is fortified is Schar with Iodized salt, nothing else.

      In the U.S., most regular wheat breads are required to be enriched with certain B-vitamins and iron, but gluten-free breads are not required to be. Since many gluten-free products are not enriched, we usually encourage people with celiac disease to consider a multivitamin.  In the early 1900s, refined white flour replaced whole grains, and people began developing serious vitamin-deficiency diseases: Beriberi → caused by a lack of thiamin (vitamin B1) Pellagra → caused by a lack of niacin (vitamin B3) Anemia → linked to low iron and lack of folate By the 1930s–40s, these problems were common in the U.S., especially in poorer regions. Public-health officials responded by requiring wheat flour and the breads made from it to be “enriched” with thiamin, riboflavin, niacin, and iron. Folic acid was added later (1998) to prevent neural-tube birth defects. Why gluten-free bread isn’t required to be enriched? The U.S. enrichment standards were written specifically for wheat flour. Gluten-free breads use rice, tapioca, corn, sorghum, etc.—so they fall outside that rule—but they probably should be for the same reason wheat products are.

While I understand wanting a formal diagnosis, it sounds like she will likely remain gluten-free either way, even if she should test negative for celiac disease (Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If her symptoms go away on a gluten-free diet, it would likely signal NCGS).

All serological markers continue to increase, and the doc who did the scope said there villous atrophy visible on the scope — but we just got the biopsy pathology report back, and all it says is, “Duodenal mucosa with patchy increased intraepithelial lymphocytes, preserved villous architecture, and patchy foveolar metaplasia,” which we are told is still inconclusive…  We will have her go gluten free again anyway, but how soon would you all test again, if at all? How valuable is an official dx in a situation like this?
