Thank you for explaining! This makes sense. 

I have been looking for new dishes. I was surprised to find dishes made of wheat straw. Are these safe for us? I'm very careful to avoid products that may contain gluten. I never thought I might have to check for wheat in dishes.

Welcome to the forum, @Hope07! The reference range would refer to what is considered normal in healthy people. So, 7 or less would mean there is no indication of "active" celiac disease. Apparently, you are doing very will in avoiding gluten. The "Tissue Transglutaminase IGA" is the centerpiece antibody test that clinicians run when checking for celiac disease. My only reservation would be that whenever the TTG-IGA test is run, a "total IGA" test should also be run to check for IGA deficiency. When IGA deficiency is present, other IGA tests, such as the TTG-IGA can be artificially low and result in false positives. In the absence of any symptoms indicating your celiac disease is not under control, however, I would take the result you posted at face value.

Going on a cruise next week and I’m a celiac. Bought a bottle of GliandinX. Should I just take two tablets per day as a precaution? Never tried this before!! Any help is appreciated!!

Hola! Not sure if I’m asking this in the right place so apologies if not! I just had a full blood count as part of my first check up after being diagnosed with celiac disease 7 years ago!! With Covid lockdowns then living in Spain for 3 years and now back in the UK, I kept getting missed in the system but finally I’ve had a check up! Does anyone know what this means?  Tissu transglutaminase IgA lev:  0.30 U/ml Reference range:  Below 7 Thank you!
