Best Lab To Get Full Panel Bloodwork For Accurate Celiac Results

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.

      Recovery from gluten challenge

      Thank you so much for your response! I have a follow-up appointment with her pediatrician next week, and also an appointment with her pediatric GI Dr. Your message gives me some ideas for questions to ask the doctors. My daughter went strictly gluten-free in January following her first endoscopy so I’m guessing her diet is pretty solid. She is compliant b...

      Recovery from gluten challenge

      While the positive endoscopy confirms the diagnosis, it's important to be skeptical of the idea that your daughter will simply "bounce back" to a pre-challenge state. The gluten challenge was essentially a controlled, prolonged exposure that likely caused significant inflammation and damage to her system; it's not surprising that recovery is slow and that...

      Brain fog

      The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium. Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend...

      Were you doing any of the new home construction yourself? Drywall compounds and adhesives used in construction have been known to cause problems for some celiacs.

      Feel like I’m starting over

      Hello @Scatterbrain and welcome to the forum I am sorry to hear you have had a return of your symptoms. My first thoughts were that stress can cause IBS-like symptoms - a friend of mine has been suffering a huge amount of stress and when that happens she gets diarrhea. But you say that you haven't got any bad abdominal issues, so perhaps you...

      Recovery from gluten challenge

      By Kirita · Posted

      Thank you so much for your response! I have a follow-up appointment with her pediatrician next week, and also an appointment with her pediatric GI Dr. Your message gives me some ideas for questions to ask the doctors. My daughter went strictly gluten-free in January following her first endoscopy so I’m guessing her diet is pretty solid. She is compliant but also reliant on others to make her food (at school and home) but she didn’t have this problem prior to the gluten challenge when she went strictly gluten-free. It really makes sense to me that the gluten challenge inflammation hasn’t healed and I will be asking her doctors about nutritional issues. I ask for anecdotal stories because the research surrounding the gluten challenge seems to be inconsistent and inconclusive (at least what I’ve been able to find!). Thank you so much for your response!

      While the positive endoscopy confirms the diagnosis, it's important to be skeptical of the idea that your daughter will simply "bounce back" to a pre-challenge state. The gluten challenge was essentially a controlled, prolonged exposure that likely caused significant inflammation and damage to her system; it's not surprising that recovery is slow and that a subsequent exposure hit her so hard. The persistent fatigue is a major red flag that her body is still struggling, potentially indicating that the initial damage hasn't fully healed or that her system is now in a heightened state of reactivity. Rather than seeking anecdotal timelines from others, her experience underscores the critical need for close follow-up with her gastroenterologist to rule out other nutrient deficiencies commonly caused by celiac flare-ups, like iron or B12, and to consult with a dietitian to scrutinize her diet for any hidden sources of cross-contamination that could be perpetuating her symptoms. The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs.

Brain fog, like other celiac disease symptoms, does improve after you to 100% gluten-free, and supplementation will also help.
