    Do you have questions about celiac disease or the gluten-free diet?


Is My Blood Test - Questionable?

Rate this topic

Recommended Posts

Hi all, I was on a gluten free diet 15 days before I had this blood test done. Can anyone help me interpret this?

Tissue Transglutaminase, IgA 7.7 reference 0.0 to 19.9

endomysial antibodies Ab screen negative

Gliadin Antibody IgG 28.6 equivocable 25.1 to 49.9

Gliadin Antibody IgA 38.3 equivocable 25.1 - 49.9

IgA 257 reference 70-312

Doesn't equivocable mean - not negative and not postitive? Unclear? Deceiving? Maybe, maybe not?

This test was done a year ago, now I'm thinking of having another blood test to see if the IgG and IgA is down and no longer "equivocable" and hopefully negative. Do you agree?

Thanks for your help.

Are you still on the diet? Are you feeling better? Retesting is done sometimes to check whether their levels have gone down. Many doctors will retest at 6 months or a year to check.

So does my original blood test really mean anything? Is it worth retesting now?

It depends on if you went gluten free or not, and what the purpose is of testing.

Yes, I am gluten free. I want to make sure I'm healing and I'm worried about cancer. My mom died of cancer, my brother has thyroid cancer. I guess I want to know if I'm on the right track.

Will the numbers go down if it was a gluten problem?

I am in the same boat as you- I had only bloodowork done 1 1/2 years ago and my results came back in the equivocal range too. At the time my GI told me to follow a strict diet for the rest of my life, etc. I did not have a biopsy done as I started eating gluten-free right after the blood test. I also didn't have the TTG test, only anti-giladin IGG and IGA testing (I didn't know there were better tests at the time). Now I too question my results and wonder if I am truely Celiac or not. I am considering doing the gene testing to see if that comes back with any more difinitive results. I don't know if I could do a gluten challenge- I'm scared to. But yet, I do want to know "for sure" if you know what I mean!

Good luck- let me know what you decide to do!

I think I wll go back and have the test taken again and see if the blood test comes back "normal". I'm just worried that some day when I'm old and sitting in a nursing home, they will start feeding me "gluten" because I don't have a "real" diagnosis!

From what I've read in a couple books that I have, (dangerous grains and Celiac Disease a hidden epidemic) they say it can take 1 to 5 years of eating gluten to have a positive test. They don't recommend it at all. A gluten challenge should only be for a day or two and only to see if there is a physical reaction.

So, is it the lab that decided my test was "equivocal". Are labs different? And is it in their interpretation of the result? Another lab would call it negative? or positive?

I enjoy listening to Ted Talks.  I found this one on dementia.  The take?  No success in developing drugs to stop dementia, so they are looking for ways to prevent it through diet!  Food can heal!   https://m.youtube.com/watch?v=f0WCb23KPEw Interesting!
