Method for analyzing a biological sample
First Claim
1. A method for analyzing a biological sample, comprising (a) providing an electrochemical analysis element comprising a sensor body having a hollow space which space is open at both of its ends, both ends being arranged along an axis of the element, an electrode system including a working electrode and a counter electrode and a reagent segment containing an enzyme, wherein said electrode system and said reagent segment are disposed on an inner wall of said hollow space, (b) pressing one of the open ends of the hollow space against a skin portion of a host from whom a sample is to be analyzed, and (c) introducing the sample into the hollow space through a filter disposed on the one open end.
