[Lipase and carboxypeptidase A in human serum: no correlation (author's transl)].

The catalytic concentrations of lipase and carboxypeptidase A in sera of patients with and without pancreatic diseases show no correlation. 40 sera out of 44 with elevated values for lipase, derived from a collective of 135 different sera, showed no increase in the catalytic concentrations of carboxypeptidase A. The demanding titrimetric determination of lipase cannot be replaced by the more simple colorimetric determination of carboxypeptidase A for the laboratory diagnosis of pancreatic diseases.
