Hello I m new at this forum. I am 24 years old. My mother and I have hypothyroidism and a day before I found out about celiac, the symptoms of celiac and hypothyroidism are almost similar and i have read that both diseases can go hand in hand. I have felt that every time when i eat macaroni and spicy rice  I have loose stool. I eat whole wheat loaf and that doesnt bother me at all. So I want to order tests for tTG IgA and immunoglobulin IgA . I m not on gluten free diet so do i need to have more gluten before tests???

Hello and welcome :)

It's true that there's aOpen Original Shared Link.  Loose stools and other digestion issues can be symptoms of celiac and you should definitely explore this issue with your doctor. This is the full celiac panel, try and get as many of these as available to you:


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

You must be eating some gluten each day up to the test date for an accurate response. 

Here's some more info. Also check out the forum FAQ  

Best of luck :)

Hi!  

It is true that there is a strong link of autoimmune thyroiditis (Grave's Disease or Hashimoto's Thyroiditis) with celiac disease because both are autoimmune disorders.  You can get screened for celiac disease by taking a simple blood test (JMG supplied excellent advice).   You do need to be on a gluten-containing diet (daily, 8 to 12 weeks prior to the blood draw) as eliminating gluten from will yield negative results.  

I wish you well.

Is total serum IgA and Immunoglobulin A (IgA) same tests??? because here in Pakistan labs perform immunoglobulin A and Immunoglobulin G. I cant find total serum IgA in menu of labs.

Ok, I may be wrong as I'm definitely not an expert, but my understanding is that immunoglobulin a would be separate from total igA.

The first test is to check your levels. The second is to check that your natural levels of igA are within the normal leveL. The reason is that some people are naturally low in igA which means that they will score low on the igA test, whether or not they are celiac:

Quote

Total immunoglobulin A (Open Original Shared Link) and IgA Anti-tissue Transglutaminase Antibody (TTG) are usually the first choice tests performed for diagnosis of coeliac disease. IgA deficiency is significantly more common in people with coeliac disease in general population. That may give a false negative result when tested for IgA TTG, which may lead to a missed diagnosis. That explains the main reason for performing these two tests together If the results of the tests described above are uncertain, then the next test that may be performed is IgA antiendomysial antibody (EMA). This can be a helpful test when the IgA TTG result is weakly positive.

The final tests that may be used are IgG EMA, IgG deamidated gliadin peptide or IgG anti TTG. These may be performed if IgA deficiency is confirmed.

If the results of autoantibody testing are positive, or if clinical suspicion remains high despite of negative findings, the patient should be referred to a gastrointestinal specialist to undergo biopsy of the small intestine (gut) to confirm or exclude the diagnosis of coeliac disease.

EMA is a test that comes back as positive or negative for celiac.

Immunoglobulin IGA is used to see if your IGA levels are high enough for TTG IGA to be valid.

Too low Immunoglobulin IGA means a negative TTG IGA has no meaning and TTG IGG neads to be used.

Yes, it is the same test. When used in conjunction with  celiac testing, it verifies that the celiac IgA  test results are valid.  Used alone (not running the celiac tests), if  the Immunoglobulin A result is above or below range....then you are dealing with another set of problems.  For example, my result was above range.  This can be attributed to my having more than one autoimmune disorder and at the same time, it validated the IgA celiac test results.

My test results came and tTG IGA is weak positive, could be due to hypothyroidism 

its 15.22U/ml

Negative: less than 8 U/ml

Equivocal: between 12 to 18 U/ml

Positive: greater than 18 U/ml

and the Serum IGA is 3.23 g/L

Range: (0.4 to 3.5)

What these results mean and what other tests I should consider?

Test results are attached.

You are correct in that other issues that could raise the TTG.  I have Hashimoto's Thyroiditis which is hypothyroidism that is due to autoimmune (like celiac disease).   I personally have never had a positive on a TTG test.  If my Doctor had not ordered the entire panel, my diagnosis would have never been caught.  

You could ask for the rest of the panel which includes the DGP and EMA.  If your sysmptoms warrant, your doctor may order an endoscopy.  About 10% of celiacs are seronegative.  

Here is more about the tests.

Even if all testing is negative for celiac disease, consider trialing the gluten-free diet.  Unfortunately there is no specific test for a gluten sensitivity, but the symptoms are real.  

Take care.

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      Terrible Neurological Symptoms

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/
