[Macroamylasemia--an rather unknown condition for Norwegian doctors?].

Three patients with macroamylasemia and different clinical problems are presented. They illustrate the importance of recognizing the macroenzymes as the cause of elevated serum amylases. Several methods exist for confirmation of the condition, as for instance electrophoresis. It may be sufficient, however, to determine serum lipase or amylase in urine that is normal. Macroamylasemia is a benign condition requiring no treatment. It is important to recognize macroamylasemia in order to avoid unnecessary, diagnostic procedures.
