My Doctor Just Called Regarding My Follow Up Blood Test

Rate this topic

Recommended Posts

So at the beginning of November I had my TTG and IGA tests done

TTG 111.6 RANGE <20 POSITIVE

IGA 56 RANGE <18 HIGH

I was on a gluten free diet for about two weeks and repeated these tests in a different lab and here are the resutsl

TTG 68 RANGE <20 POSITIVE

IGA 268 RANGE <18 HIGH

Why is it that after going gluten free my IGA rose and my TTG dropped, my idiot doctor has no explanation and my GI told me to see him in 6 months

What is wrong with this?

Theoretically, one would expect both ranges to drop on a gluten free diet. However, of the two tests the tTG is the more important/specific one and the one to rely on. I cannot explain either why your IgA made such a huge jump unless it was lab error, although my (limited) understanding is that this one can be "unstable". The important aspect is that they were both positive and you should be gluten free. :)
