Abstract

Disclosed is an electrode probe and a body fluid examination equipment enabling examination of a trace amount of body fluid. The electrode probe comprises an insulating needle member, a working electrode lead disposed in the needle member, a working electrode whose lead is protruding outside from the needle member, a counter electrode disposed on the surface of the needle member, a lead connected to the counter electrode, and a reagent layer disposed in contact with or in the vicinity of the working and counter electrodes of the electrode system. When a trace amount of body fluid leaking on the skin surface is brought into contact with the reagent layer, the reagent layer dissolves which results in electron transfer whereby information about the concentration of analyte in the body fluid can be obtained from the electrode system.
