Negative blood test but can I still have it?

[Heyleyz]

Hi everyone, I hope you're all doing well.

I just received my blood test results which were all negative, but I read somewhere that some people can have a false negative. I'm still waiting for my biopsy test results to confirm but I would like to see what you think of my results. I will include the normal values provided by the lab.

Anti-Transglutaminase (tTG IgA):

My results: <5 U/ml

Normal values: <7

 

Anti-Transglutaminase (tTG IgG):

My results: <5 U/ml

Normal values: <7

 

IgA Anti-Endomysium:

My results: <10

Normal values: <10

 

IgG Anti-Endomysium:

My results: <10

Normal values: <10

 

Gliadine IgA:

My results: 5 U/ml

Normal values: <7

 

Gliadine IgG:

My results: <5 U/ml

Normal values: <7

 

Sorry if I messed up some names of the tests, my report was in French. Please tell me what you think and if there still is a possibility that I might have Celiac.

Thanks in advance!

One test that seems to be missing from the celiac panel is total IGA. If that is low, it can drive down the numbers in other IGA tests. And were you consuming regular amounts of gluten in a two month window leading up to the blood draw. Many people make the mistake of beginning the gluten free diet before testing is complete which will invalidate the testing.

There is also the possibility that you have NCGS (Non Celiac Gluten Sensitivity) for which there are not tests but it shares many of the same symptoms with celiac disease. Are you reasonably certain gluten is causing you issues? What symptoms do you have that led you to seek celiac testing?

Keep us posted with the biopsy results.
