Transglutaminase In My Yogurt?

I was reading the ingredients of my yogurt and one of them was "transglutaminase". Isn't this what they test for to find out if you have celiac? I tried to find out if it is safe to eat but I couldn't find out it if has gluten in it or not. Can anyone shed some light on this for a newbie.

That ingredient would make me wonder also. Have you tried contacting the company about whether this is gluten-free or not? Sometimes if you put the brand name of the product and the word gluten into google the companies gluten policies will show up close to the top of the results. Many yogurts are not gluten-free so you are wise to question this.

To be on the safe side I would not eat it. People with celiac disease mount an immune response to this enzyme (when bound to gluten?) and this is what ends up causing intestinal damage.

What yogurt are you talking about? :ph34r:

If it has wheat in it, then wheat is required to be listed (just to keep in mind).

It's Danone peach flavoured. I read on this forum that this brand is gluten-free in Canada. Can I trust this?

I don't know about other countries but in the US Dannon yogurts are not gluten-free this is their statement on gluten-

"Gluten is a protein found in wheat, oats, rye and barley.DANNON yogurt products are not formulated to containgluten, but they cannot be considered gluten free. This is because the natural flavor system used might have ingredi-ents added to stabilize the flavor. These ingredients can be derived from gluten sources. Since there is a currentlack of consensus on individual sensitivity levels to glutenand there are no accurate tests to detect the presence andamount of gluten, DANNON

Transglutaminase is NOT gluten or any byproduct of gluten. It is an enzyme that catalyzes the reaction of the amino acid glutamine (again NOT related to gluten) with free amino acids. It is a safe ingredient.

      Thoughts? Non-endoscopic Celiac diagnosis in two year old

      So her tissue transglutaminase antibody is almost 4x the upper end of the normal range - likely a real result. The other things you can do besides an endoscopy would be: 1. Genetic testing.

      here are the lab ranges. Normal ranges for tissue transglutaminase are: <15.0 Antibody not detected > or = 15.0 Antibody detected normal for endomysial antibody is < 1.5. So she is barely positive but still positive.

      Just diagnosed today

      I have been diagnosed with coeliacs disease today after endoscopy, bloods and CT scan. I have also been diagnosed with Mesenteric Panniculitis today. Both of which I believe are autoimmune diseases. I have been told I will need a dexa scan and a repeat CT scan in 6 months. I had not even heard of Mesenteric Panniculitis till today. I don’t know much about i...

      Thoughts? Non-endoscopic Celiac diagnosis in two year old

      The normal ranges can vary for the tissue transglutaminase and gliadin antibody celiac tests because the units aren’t absolute. Could you please tell us what the normal ranges are for the laboratory used? If her tissue transglutaminase results are 10-fold above the normal range some would diagnose her on that alone. Endomysial antibody ranges are m...

      So her tissue transglutaminase antibody is almost 4x the upper end of the normal range - likely a real result. The other things you can do besides an endoscopy would be: 1.  Genetic testing.  Unfortunately a large proportion of the population has genes permissive for celiac disease, but only a small proportion of those with the genes have it. With family history it is likely she has the genes. 2.  Try a gluten free diet and see if the symptoms go away AND the antibody levels return to normal. (This is what I would do). Endoscopies aren’t always accurate in patients as young as your daughter. Unfortunately, without an endoscopy, some doctor later in her life may question whether she really has celiac disease or not, and you’ll need to be a fierce mama bear to defend the diagnosis! Be sure you have a good written record of her current pediatrician’s diagnosis. Doing a gluten challenge for an endoscopy later in life could cause a very uncomfortable level of symptoms.   Having yourself, your husband and your son tested would be a great idea.

If her tissue transglutaminase results are 10-fold above the normal range some would diagnose her on that alone.  Endomysial antibody ranges are more standardized, and a titer of 1:5 would usually be normal.  Might that be the normal range and not her result?  Her total immunoglobulin A is normal for her age. (This is tested because if low, then the other IgA tests might not be valid).

      Hello there! New to celiac community, although I have lots of family in it.  My two year old was just diagnosed with celiac disease based on symptoms and bloodwork.  symptoms (swollen belly, stomach hurting, gagging all the time, regular small vomit, fatigue, irritability, bum hurting, etc) she got tests at 18 months and her bloodwork was normal. She just got tested again at 2 1/2  because her symptoms were getting worse and these were her results :   Tissue Transglutaminase Ab, IgA 58.8 Unit/mL (High) Endomysial Antibody IgA Titer 1:5 titer (Abnormal)   Gliadin Antibody IgA < 1.0 Unit/mL Gliadin Antibody IgG 8.5 Unit/mL Immunoglobulin A 66 mg/dL Her regular pediatrician diagnosed her with celiac and told us to put her on the strict gluten free diet and that we wouldn’t do an endoscopy since it was so positive and she is so little (26lbs and two years old). I’m honestly happy with this decision, but my family is saying I should push and get an endoscopy for her. It just seems unnecessary and an endoscopy has its own risks that make me nervous. I’m certain she has celiac especially with it running in mine and my husbands family. We are now thinking of testing ourselves and our 5 year old as well.  anyways what would y’all recommend though? Should we ask for an endoscopy and a GI referral? (We are moving soon in 5 months so I think that’s part of why she didn’t refer us to GI)
