This information came to me from Michael Walker (firstname.lastname@example.org) of Genesis Diagnostics Ltd.
Genesis Diagnostics is a manufacturer of ELISA based kits for autoimmune diagnosis. We already produce kits for gliadin IgG and IgA antibodies, which have been used for the past 5 years as the main test for celiac disease. The new test for transglutaminase was an obvious development of our experience in this area. We will continue to develop and improve blood tests in this area.
We will be seeking FDA approval for the transglutaminase test kit in 1999. In the mean time it can be used for research only.
