Blood Testing Reference Ranges Vs "positve" For Celiac

Recommended Posts

I had the ttg-iga test done and was told the results were negative. I had 4.0 and to be positive (I am assuming positive for possible celiac disease) you would need to be 10.0 or more. Then today I noticed that the lab who ran the test had redone their website and one of the improvements was to post all reference ranges for the tests they do. According to them normal is .7 to 4.0.

My question is: what is this area between 4.0 and 10.0? Am I misunderstanding something here? Does the 10.0 correlate with villous atrophy?

Can you call the lab and seen when they changed their reference ranges and maybe ask them why. How long ago did you have yours done.

If you read around here, tests do not correlate at all with villious atrophy.....

Some have weak tests, some negative and some have strong positive tests with villious atrophy.

maybe the 4-10 range is the grey zone and you had a very very weak positive and they told you it was negative. It would have been usefult to know so you could have had a biopsy.

gluten-free since may 06 after neg. biopsy symptoms went away and DH symptoms which I had since 03 got gradually better.

daughter officially diagnosed celiac and casein intolerant.

non-DQ2 or DQ8. Maybe DQ1? Updated: Yes, double DQ5

Hypothyroid since 2000, thyroxine first started to work well 06 on a low-carb and gluten-free diet

Lost 20 kg after going gluten-free and weighing 53 kg now. neg. biopsy for DH. Found out afterwards from this forum that it should have been taken during an outbreak but it was taken two weeks after. vitaminD was 57 nmol/l in may08)

different labs run the tests somewhat differently, and so will have different reference ranges. where did you see the 10.0 for a positive versus the 4.0?
