Based on these bloodwork this would indicate celiac disease?

Hello,

I recently got some blood work done and it is as follows: 

tissue transglutaminase IgA: 24.0 U/mL (range <7.0 U/mL)

tissue transglutaminase IgA interpretation: positive.

i have seen my dr, and he does day it is very likely celiac disease and has referred me to get biopsy but the wait times here can be long. I asked him how likely it would be having this blood work be this but biopsy be negative and he said that could happen but the blood work would still indicate celiac. I am in the dark on this condition and would be grateful for some advice! Thank you!

I agree with your doctor's interpretation. Specifically, what advice are you seeking? The one piece of advice you do need to hear is not to begin a gluten free diet until the biopsy is complete. Be sure to eat plenty of gluten containing foods until the biopsy is done or you risk invalidating the biopsy.

Thank you for responding! I guess the advice I was seeking that if the biopsy did for some reason come back negative, that I should still be under the assumption that I do have celiac disease?

Biopsies do indeed come back negative sometimes for those who actually do have celiac disease and for three chief reasons:

1. The damage is patchy and the sampling was not thorough enough.

2. The celiac disease is in the very early stages and has not produced sufficient damage to show on the biopsy.

3. The gluten free diet was begun ahead of the biopsy

Yes, if the biopsy comes back negative, if I were you I would operate under the assumption that you do have celiac disease and begin the gluten free diet. If symptoms improve after going gluten free, well . . . the proof is in the pudding.

      Welcome to the forum! Keep in mind that if you quit eating gluten before all testing is done, you may have inaccurate, possibly false negative, test results.  When you stop eating gluten, your body stops making the antibodies which are measured in the blood tests.  Stopping gluten before an endoscopy may make the intestinal damage harder to detect, and a false negative biopsy may result.  As uncomfortable as it is, finish all testing before going gluten free.

      Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy: and this recent study recommends 4-6 slices of wheat bread per day:

      Your feelings are completely valid, and I want to commend you for advocating for yourself despite the initial resistance from your doctor. Navigating a new celiac diagnosis can feel overwhelming, especially when you're adjusting to such a big lifestyle change. It’s natural to grieve the loss of your old eating habits and to feel frustrated by the constant label-reading and vigilance required. But please know that you are not alone, and many others have walked this path and come out stronger on the other side. Healing takes time, and while the brain fog, fatigue, and bowel symptoms can be discouraging, they often improve as your body begins to recover. It’s great that you’ve hired a dietitian—that’s a big step in supporting your healing journey and ensuring you’re getting the nutrients your body needs to rebuild. Remember, each small step you take is progress, even if it doesn’t feel like it right now. It’s okay to feel sad and angry, but also try to give yourself credit for your strength in facing this. The fact that you pushed for answers shows how resilient you are. While the road ahead may have challenges, many people find that over time, they feel better than they ever imagined possible once their gut begins to heal. You’ve got this, and the celiac community is here to support you every step of the way. If you have time, this book was published on Celiac.com's and you might find it helpful: Also, this article has some detailed information on how to be 100% gluten-free, so it may be helpful (be sure to also read the comments section.):

      Welcome to the forum, @Whyz! By "half way to being diagnosed" I assume you mean you have had the blood antibody testing done but not the gastroscopy with biopsy. Is this correct? Were the results of your blood work positive for celiac disease?
    • trents
      Three days of no gluten is not likely to have much impact on serum antibody test results. I have more concern over exactly what test or tests were ordered. When you get the results back, please post them including the reference ranges for the tests for negative vs. positive. What country are you in? Do you have much choice in what doctors you see? Sounds like it might be a good idea to seek out another physician who knows what they are doing in this area of disease diagnosis. At any rate, you have the link I shared above outlining the various tests that can be run so that might be a resource you could share with a physician.
