I read that different labs use different testing techniques which can effect TTg-Iga results. Which Lab should I have my TTg-Iga blood test and which one does a full panel test?

The antibody blood tests used to diagnose celiac disease are standardized in the sense of what is being measured. How the tests are conducted and the scales used (as well as the units used) to express the results can vary from lab to lab. This does not affect the accuracy of the testing. So, there shouldn't be an issue with choosing one lab over another to ensure testing accuracy. What you don't want to do is to compare test results from two different time periods done by two different labs. If you are wanting to compare blood antibody test results over time, then the tests would need to have been done by the same lab in order for the comparison to be meaningful. And by the way, the TTG-IGA is not the only celiac antibody test that can be run nor is the only one that should be run. At least a "total IGA" test should be ordered whenever the tTG-IGA is ordered to make sure the tTG-IGA result is not invalidated by IGA deficiency. Here is an article outlining the various tests that can be ordered to diagnose celiac disease:

I agree with @trents, but for genetic tests it does seem like there are some variations between different labs and the celiac gene markers that are included, but for your celiac disease blood test just make sure that a full celiac disease panel is done that includes total IgA.

      My journey is it gluten or fiber?

      @xxnonamexx, There's labeling on those Trubar gluten free high fiber protein bars that say: "Manufactured in a facility that also processes peanuts, milk, soy, fish, WHEAT, sesame, and other tree nuts." You may want to avoid products made in shared facilities. If you are trying to add more fiber to your diet to ease constipation, considering...

      Issues before diagnosis

      Welcome to celiac.com @sha1091a! Your experience is a very common one. Celiac disease is one the most underdiagnosed and misdiagnosed medical conditions out there. The reasons are numerous. One key one is that its symptoms mimic so many other diseases. Another is ignorance on the part of the medical community with regard to the range of symptoms that celiac...

      Celiac Disease Patients Face Higher Risk of Systemic Lupus

      What kind of practitioner did the blood test? Was this a medical doctor, a naturopathic doctor, a GI doc? I would certainly follow up with them and ask why they advised you not to eat red meat. I mean, it could be something like they, themselves, are a vegetarian and give that advice to everyone. Have you had an endoscopy with biopsy of the small bowel...

      Dizziness after eating green beans?

      @EndlessSummer, You said you had an allergy to trees. People with Birch Allergy can react to green beans (in the legume family) and other vegetables, as well as some fruits. Look into Oral Allergy Syndrome which can occur at a higher rate in Celiac Disease. Switching to a low histamine diet for a while can give your body time to rid itself of...

      Issues before diagnosis

      I found out the age of 68 that I am a celiac. When I was 16, I had my gallbladder removed when I was 24 I was put on a medication because I was told I had fibromyalgia. going to Doctor’s over many years, not one of them thought to check me out for celiac disease. I am aware that it only started being tested by bloodwork I believe in the late 9...

You may want to avoid products made in shared facilities.   If you are trying to add more fiber to your diet to ease constipation, considering eating more leafy green vegetables and cruciferous vegetables.  Not only are these high in fiber, they also are good sources of magnesium.  Many newly diagnosed are low in magnesium and B vitamins and suffer with constipation.  Thiamine Vitamin B1 and magnesium work together.  Thiamine in the form Benfotiamine has been shown to improve intestinal health.  Thiamine and magnesium are important to gastrointestinal health and function.

      Welcome to celiac.com @sha1091a! Your experience is a very common one. Celiac disease is one the most underdiagnosed and misdiagnosed medical conditions out there. The reasons are numerous. One key one is that its symptoms mimic so many other diseases. Another is ignorance on the part of the medical community with regard to the range of symptoms that celiac disease can produce. Clinicians often are only looking for classic GI symptoms and are unaware of the many other subsystems in the body that can be damaged before classic GI symptoms manifest, if ever they do. Many celiacs are of the "silent" variety and have few if any GI symptoms while all along, damage is being done to their bodies. In my case, the original symptoms were elevated liver enzymes which I endured for 13 years before I was diagnosed with celiac disease. By the grace of God my liver was not destroyed. It is common for the onset of the disease to happen 10 years before you ever get a diagnosis. Thankfully, that is slowly changing as there has developed more awareness on the part of both the medical community and the public in the past 20 years or so. Blessings!

      I found out the age of 68 that I am a celiac. When I was 16, I had my gallbladder removed when I was 24 I was put on a medication because I was told I had fibromyalgia.   going to Doctor’s over many years, not one of them thought to check me out for celiac disease. I am aware that it only started being tested by bloodwork I believe in the late 90s, but still I’m kind of confused why my gallbladder my joint pain flatulent that I complained of constantly was totally ignored. Is it not something that is taught to our medical system? It wasn’t a Doctor Who asked for the test to be done. I asked for it because of something I had read and my test came back positive. My number was quite high.Are there other people out here that had this kind of problems and they were ignored?

      Welcome to celiac.com, @EndlessSummer! Do you react to all vegetables or just specific kinds or families of them? What you describe with green beans sounds like it has an anaphylaxis component. Like you, walnuts are a problem for me. They will often give me a scratchy throat so I try to avoid them. Does it matter if the vegies are raw or will-cooked in how you react to them?
