Thanks you two - I'm seeing my GP tomorrow I will ask about the celiac panel. I know I've had some celiac bloods done but I think it was just a subset of the list you cited NVSMOM. How reliable are the results though ?? I hear false-positives and false-negatives are not uncommon??
False positives are very rare. I think it gets as high as 5% for the tTG IgA test but it would be a weak (false) positive and is probably caused by thyroiditis, diabetes, liver disease, crohn's, colitis, or a serious infection... The positive is caused by something in all cases but 95% of the time it is caused by celiac disease.
False negatives are much more common. The biopsy can have a false positive rate as high as 20%, especially if fewer than 6 samples were taken. The blood tests can have a false negative rate as high as 25% based on the test's sensitivity - that's why it is a good idea to get as many tests done as possible.
This report (page 12) shows the sensitivities of most of the tests, as well as how specific the results are to celiac disease (% of positives caused by celiac disease): http://www.worldgast..._long_FINAL.pdf
Hang in there!
