Guest guest Posted June 25, 2008 Report Share Posted June 25, 2008 Well, not an " expert " yet, but from what I understand, if cost is an issue, I'd start with IgA TTG. If positive, then go biopsy. If negative, total IgA should be tested. If total is negative, then TtG negative may be false negative, and no point in paying for IgA EMA. I don't know the accuracy of gliadin antibodies off the top of my head, but think not that great. No time to look it up either. Some docs use stool testing from Enterolabs and find that if the above are negative, but enterolabs comes back positive, then base diet on the enterolab results, and patients often well.

Guest guest Posted June 25, 2008 Report Share Posted June 25, 2008 Below is the comprehensive celiac panel offered by Quest. Total IgA is important because if a person is deficient tTG and/or EMA maybe be inclonclusive. Quest has another panel that does not include Total Iga and is used to assess response to the GF diet and possible diet compliance. There is also the HLA typing for celiac offered by Quest and Prometheus. These test tend to be more expensive. I'd also recommend checking out Prometheus website for explanation of celiac blood tests. _http://www.questdiagnostics.com/hcp/topics/gastroent/celiac.html_ (http://www.questdiagnostics.com/hcp/topics/gastroent/celiac.html) Celiac Disease Comprehensive Panel Benefits • Assists physicians in differentiating celiac disease from irritable bowel syndrome • Enables early detection of gluten sensitivity, which may help avoid progression of celiac disease, particularly in children • Useful in monitoring adherence to gluten-free diet Panel Comprises: • Tissue Transglutaminase (tTG) Antibody, IgA • Gliadin Antibody, IgA • Total IgA • Endomysial Antibody (EMA) Screen, IgA- performed (at additional charge) when the anti-tTG IgA is positive • EMA Titer-performed (at additional charge) when the EMA screen is positive • tTG Antibody, IgG-performed (at additional charge) when total IgA is low In a message dated 6/25/2008 11:03:42 AM Eastern Daylight Time, jdsimon@... writes: When you are screening a patient for celiac there are several lab panels to choose from.
