In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.

Celiac.com 05/10/2004 - Italian researchers compared the serum samples from 39 celiac disease patients who were diagnosed with celiac disease after their first biopsy with 32 controls who had normal duodenal mucosa and 32 healthy volunteers. Salivary transglutaminase autoantibodies were detected in 97.4% of the patients who had celiac disease, and in 100% of their corresponding serum samples. All of the 32 healthy volunteers tested negative for both serum and saliva transglutaminase autoantibodies. The researchers conclude "This study demonstrates that it is possible to detect salivary transglutaminase autoantibodies in celiac disease with a non-invasive, simple to perform, reproducible and sensitive method."
