ABSTRACT
Chapters 5A and B summarize the findings of two independent groups, one in Tampere, Finland which initially worked on IgA-ARA tests, and one cooperating group of two laboratories, one in Warsaw, Poland, where the IgA-EmA were recently described and one in Buffalo, NY. These three laboratories joined forces to compare these two test systems. Additionally, each group made some comparisons of these two tests to the AGA tests.
