A method and apparatus for determining the production of certain substances secreted in the body, for instance such substances as hydrochloric acid, bile salts, pancreas enzymes, pepsins, trypsins, porphyrins, nitrogen oxide and carbon dioxide. A dialyzable calibrating substance (21) is added to body fluid to a known extent, said calibrating substance containing the substance whose production shall be determined; the amount of calibrating substance dialyzed in a dialysis catheter in time is determined, the amount of substance whose production shall be determined dialyzed in the dialysis catheter in time is determined and a quotient (F(t)) between the added and dialyzed quantities of calibrating substance in time is determined and is correlated with a corresponding quotient (G(t)) for the substance whose production shall be determined, so as to determine said production. |
