More than half of the physicians received our report evaluated the information on macroamylase in the questionnaire. Macroamylasemia found in this study consisted of IgA type immunoglobulin in 92% and mostly had high activities in the serum. The back-ground of these patients with macroamylasemia were 10 cases of hepato-biliary disease, 9 cases of diabetes mellitus, 8 cases of autoimmune disease and so on.
