Daughters Celiac Blood Results - would love insight


Eightysix

Recommended Posts

Hi all! I would love having your opinions on her blood work. She’s been referred to a gastroenterologist (which she will see Monday) but her blood work is confusing. 
 

A little background - she had had a dairy allergy since birth and continues to have stomach issues quite often. She will have to use the bathroom almost immediately during some meals and we can’t pinpoint exactly what causes it. My sister is gluten free after a lifetime of skin issues but does not have a formal celiac diagnosis and after going gluten-free, saw a decrease in her cholesterol and resolve of her Hashimotos.

 

DGA-Iga: 3 (0-19 normal)

DGA-igg: 1 (0-19 normal)

TTA-Iga: <2 (0-3 normal) 

Tissue Transglut Ab: 9 (0-5 normal)

Endomysial iga: negative 

Total Iga: 124 (51-220 normal)

 

her pediatrician declared it a positive result, hence the referral, but I’m unclear what, exactly, that positive test was measuring. Any thoughts?

Eightysix, welcome to the forum!

The test abbreviations you post are different than we are used to seeing. The most common celiac antibody test ordered by physicians and the most well-rounded one is what we know to us as the tTG-IGA. I'm not sure which of your posted results would correspond to that. Would that be "TTA-Iga" or "Tissue Transglut ab"? 

Perhaps one of our other mods with more knowledge in this area can clear this up.

At any rate, the test results are mixed and not giving a clear indication of celiac disease but the one positive would seem to point to the possibility. The GI referral may be due to needing an endoscopy with biopsy of the small bowel lining to get a clearer answer. The biopsy looks for actual damage to the small bowel villi caused by celiac disease and is considered the gold diagnostic standard.

Yes, that was supposed to be “TTG-IgA”. I’m unclear what the “Tissue Transglut Ab” is, but that is how it appears on her test results! Thank you for your reply!

This is just a guess, but the Tissue Transglut Ab: 9 (0-5 normal) might be the tTG-IgG (tissue transglutaminase IgG) Blood Test for Celiac Disease here:

 

There are two types of tissue transglutaminase tests, and perhaps she was positive on the IgG?

      I did a test already not exactly sure if it was the right one the doctor I went to at first refused to give me the test but i evantail convinced him but he wasnt exactly sure what test to do. I didn't eat gluten on sunduy monday tuesday and i had the test on thursday. Is it possible the test will still be accuret

      I was just thinking this same thing - requesting repeat testing prior to giving up gluten. Makes sense. Thanks!

      Since you're having a last hurrah with gluten, request another round of blood tests for celiac antibodies.  Make sure you're eating ten grams or more daily for those few weeks before your capsule endoscopy.  You probably weren't eating a sufficient amount of gluten needed to provoke sufficient antibody production.

      Hello all I am taking some time out from work today to make my annual Christmas cake along the lines of a tried and tested English recipe which means a fruit cake, with marzipan  and icing.   As usual, I've left it too late - we're meant to bake these things some time  in advance to improve the flavour.    I never remember.  But it never seems to matter! I thought I'd share it in case any UK coeliacs still haven't made theirs and don't have a recipe, or any of my friends across the Pond want to try making one.  Do you make iced fruit cakes like this in the US for Christmas? - I have no idea! I adapt it slightly as instead of fondant icing I make Royal Icing which sets hard and you can create exciting snow scenes with it if you can find any tiny model houses, churches and trees to put on it!  (my Mum used to do this).   https://www.coeliac.org.uk/information-and-support/your-gluten-free-hub/home-of-gluten-free-recipes/1511804/ With thanks to the charity Coeliac Uk for this recipe.

      Welcome to the forum, @Art Maltman! Ask your physician to order serum antibody tests specifically designed to detect celiac disease. That's the place to start but you shouldn't be on a gluten free diet some weeks before the blood draw. You certainly have some symptoms that are characteristic of celiac disease and you have a first degree relative that has celiac disease. So, I think this would be an appropriate request to bring to your physician. Here is an article outlining the various serum antibody tests that can be ordered when checking for celiac disease:   The physician may not be open to ordering a full panel but push for at least these two: total IGA and tTG-IGA. By the way, absence of gut pain is very common in the celiac population. We call them "silent" celiacs as they have no or very minor symptoms. There are over 200 symptoms and spinoff health issues that have become associated with celiac disease and the range of symptoms and effects produced by the disease in different individuals various tremendously.
