Is It Possible To Have Inaccurate Biopsy?

[lharper]

My daughter was diagnosed with Celiac disease in November of 2008. It started because she has Type 1 Diabetes and I asked them to test her for Celiac due to some symptoms she was showing. Well, the initial blood work came back and her Ttg level was greater than 100. This was followed up by a biopsy that they said confirmed the diagnosis. Well, at the 6 month follow up they ran her blood work and it came back that her Ttg was at 1.2 Even the doctor was a little surprised it had came down that fast. I know the chances are she really does have Celiac and I accept that, but the fact that it came down so fast made me wonder if it is at all possible that the original blood test/biopsy could have been wrong and/or could she have something else and not Celiac? I just would hate for her to have to be gluten-free for the rest of her life for nothing... thanks!

It's my understanding that Ttg can come down pretty darn fast, particularly in a child. I was in my 40s and mine went from 200 to below 20 in less than 6 months.

It's HIGHLY unlikely that both the blood test and the biopsy would be false positive. And if her symptoms got better, that just adds to the evidence.

I'm not a doctor, but I'd say she has celiac disease.

Right, I am pretty sure that she does have Celiac as well. But I had read so many posts on here previously about how long it usually takes for the Ttg to come down so it kind of made me wonder. -l- I guess a little wishful thinking on my part.

If she has been gluten-free for the last 6 months, then her TtG is SUPPOSED to come down.

In fact, I have always read on this site that if you have been gluten-free for more than a week, your blood tests will likely be a false negative.

If you are not eating gluten, you will not be producing antibodies against it, and you will be unlikely to be producing gluten-induced auto-antibodies.

The gluten-free lifestyle is getting easier and easier, and I really think that things will continue to get even better, as more and more people are finally being diagnosed.

If it makes you feel any better about things, when we challenged my middle kid and gave him gluten, he was crying (from the stomach pain) on the toilet a few hours later, and he said, "I never want to eat gluten again!"

He was 9 years old. He has never even wanted to cheat since then.

It helps that he knows that I will (easily) find a gluten-free recipe for anything he sees that he would like to eat, and within a week, I'll make it for him if he asks.

generally, it's more likely that someone having a hard time lowering their antibodies is going to post them. so, you've got a skewed sample. and some of us never have gotten a retest.

No the original tests were not wrong. You are doing a great job of keeping her gluten free! Keep it up.
