Blood Test Results - Any Insight?

Hi guys,

I was hoping the more experienced people around here might be able to provide some advice on my test results?

IgA 1.52 g/L

Gliadin IgG <1 U/mL

TTG IgA <1 U/mL

firstly, I already know they're negative. The doctor told me that much, she didn't give me any details or explanation though. So what kind of range would positive celiac tests show up with? and did she run all the vital tests. Here's to hoping I didn't miss any! :)

Thanks in advance!

One is the total IgA, the other is gliadin IgG, a not so specific test, and another is the tissue transglutaminase IgG.

You lack the endomysium test, and the deamidated gliadin test. And, the biopsy.

Lots of biopsy proven celiacs are negative on blood tests, at least 10-20%.

A positive test would be above whatever cutoff the diagnostic lab provides. It can be very different from lab to lab with the celiac tests because the units of measurement are not standardized. You would have to ask your doctor for the "reference range" of the diagnostic test to know what a positive result would be.

Nora's comments are accurate, as always!

      gluten-free Oatmeal

      By Scott Adams · Posted

      Oats naturally contain a protein called avenin, which is similar to the gluten proteins found in wheat, barley, and rye. While avenin is generally considered safe for most people with celiac disease, some individuals, around 5-10% of celiacs, may also have sensitivity to avenin, leading to symptoms similar to gluten exposure. You may fall into this category, and eliminating them is the best way to figure this out. Some people substitute gluten-free quinoa flakes for oats if they want a hot cereal substitute. If you are interested in summaries of scientific publications on the topic of oats and celiac disease, we have an entire category dedicated to it which is here: https://www.celiac.com/celiac-disease/oats-and-celiac-disease-are-they-gluten-free/
