Abstract
An Electrochemical biosensor system which can do selectively quantitative analysis of blood sugar, cholesterol and other elements in blood is disclosed. The electrochemical biosensor test strip used in this invention is provided with recognition electrode which indicates that a fixed reagent is used for what material'"'"'s quantitative analysis. The readout meter used in this invention discriminates the use of inserted test strip by auto-recognition of the location of said recognition electrode and performs predetermined algorithm. According to this invention, it has advantage that various blood elements such as blood sugar, cholesterol, GOT and GPT can be analyzed quantitatively by one readout meter.
