Should I get an endoscopy if test results are...

Hi, my doctor said I can take the endoscopy with duodenal to rule out celiac disease since my TTG IgG was positive. But since my IgA was such a low yield she recommends I get other blood works done before considering taking the endoscopy.  Here's a list of my results of the test she wanted me take 

 

  • IgA:  0.21     normal range is <= 0.90 (negative)I
  • IgG:  1.28     normal range is <= 1.28 (positive)
  • Thyroid Stimulating Hormone (TSH)
    4.47  ulU/mL     range 0-4  (slightly above normal)
  • Free Thyroxine (T4)    1.1 ng/dl     (Dr. says normal)
  • C-Reactive Protein), Serum
    <0.1 mg/dl      (Dr. says normal)
  • Erythrocyte Sedimentation Rate (ESR)
    15 mm/hr      range 0-20 mm/hr   (normal)
  • Complete Blood Count   (Dr. says everything was normal here)
  • White Blood Cell Differential ( Dr. says everything was normal here)
  • Screen for Fecal (Stool) Fat   (Everything was normal)

It looks like  based on my results that everything is normal but my IgG antibody was high, and I have slight hypothyroidism which my dr. said they will monitor.  I'm thinking maybe I won't take the endoscopy and just assume I have a non-celiac gluten sensitivity since there's not enough evidence that I have celiac.  My symptoms right now are diarrhea, distension, itchy skin/burning rash on face, bloating, abdominal pains, tinnitus, sinus issues, anxiety, and restless legs at night. I find my symptoms improve when off gluten and wanted to know if I have celiac so I don't make myself even more sick in the future. I want to know if I should be even more strict about avoiding gluten than I am now and not cross containment. 

Thanks for reading my post!

hey that's definitely confusing. i'm assuming the first Iga result ttg iga? i agree with your doctor that you should peruse further blood tests for celiac disease. get your total iga checked to rule out an iga deficiency as that can cause false negatives on the ttg iga. i would also ask for dgp iga and dgp igg or a full celiac panel. i believe it is possible to have false mild positives on the ttg igg caused by other illnesses not sure if hypothyroidism can do that. you could also consider doing the genetic test.

were you eating gluten for a few weeks leading up the blood test?

do you any iron or vitamin deficiencies? that can be another indicator of malabsorbion caused by celiac

i think its definitely worth doing those tests now to find out more info before you are completely gluten free as it will probably be alot harder to do a gluten challenge for them if you decide you want a diagnosis after being gluten free for a while.

If you can get an endoscopy (and you have been on a gluten-containing diet -- go for it.  I personally test positive only to the DGP IgA test.  Never a positive on anything else even on follow-up testing.  Now, my GI only orders the DGP IgA to monitor diet adherence.  Weird, but true.  

You have so many symptoms.  I would find the source.  I would not accept a hypothryoidism diagnosis without a thyroid antibodies panel  to rule out autoimmune thyroiditis (which seems to go hand-in-hand with celiac disease).  

Like Emma said, the other celiac panel tests  (EMA and an IgA deficiency test) should have been ordered.  If you are IgA deficient,  it would tell the doctor that neither the TTG IgA or DGP IgA would be valid.  I do not see those tests listed.

This is the full, current celiac blood panel:

Anti-Gliadin (AGA) IgA
Anti-Gliadin (AGA) IgG
Anti-Endomysial (EMA) IgA
Anti-Tissue Transglutaminase (tTG) IgA
Deamidated Gliadin Peptide (DGP) IgA and IgG
Total Serum IgA 

 


Also can be termed this way:

Endomysial Antibody IgA
Tissue Transglutaminase IgA 
GLIADIN IgG
GLIADIN IgA
Total Serum IgA 
Deamidated Gliadin Peptide (DGP) IgA and IgG

You should have ALL of those tests done. You need to investigate this instead of just taking the attitude you are taking and I don't mean that in a mean way. This is serious stuff & you should pursue a real diagnosis. You need to continue eating gluten all the way through testing including an endoscopy. The endoscopy is easy. You don't eat or drink anything after midnight, go in, they put you to sleep (briefly - like 20 mins.) & you're done. The doc should take 6 biopsies.

      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...

      Thank you all so much for your advice and thoughts. We ended up having another scope and more bloodwork last week. 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 int...

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).

      Thank you all so much for your advice and thoughts. We ended up having another scope and more bloodwork last week. 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?
