Hi Ruchie - I haven't seen any stats on that. I just know that you can definitely test false-negative for celiac, especially if you've been avoiding gluten before taking the test. In fact, this is true not just for the blood test, but for the intestinal biopsy as well. If someone realized they had a problem with gluten before it caused permanent physical damage to their GI tract, and then carefully avoided gluten, their intestines could look normal on the biopsy. The biopsy will reveal damage - if past damage wasn't permanent and the person recovered, and prevented future damage by avoiding gluten, their intestine would look (and be) normal.
The best current info I've seen on celiac was in the periodical Today's Dietitian from February 2003. Unfortunately, that info is not posted on their website. You might check your local library (especially if you have a local university or medical library you can access) for this periodcal, or talk to the librarian about having them track down a copy for you. The article was excellent, and it discussed in detail all the various tests for celiac (tests I'd never even heard of or seen described anywhere else), what their false negative rates were, the different types of celiac and which tests are best for the different types, and more. You might also be able to order a back copy from the magazine website web page
Best,
Heather
