METHOD FOR FAST MEASUREMENT OF SPECIMEN CONCENTRATION
First Claim
1. A method for fast measurement of a specimen concentration in a short time which needs at least a sensing strip with an electrode test region on which an enzymatic reagent with a specific ingredient is coated and comprises steps as follows:
- Step 1;
Place a specimen on the electrode test region of the sensing strip;
Step 2;
Apply a high voltage on the electrode test region for a period in order to accelerate equilibrium of a non-faradic current;
Step 3;
Apply a measuring voltage less than the high voltage or the same as the high voltage in Step 2 on the electrode test region to generate an electrochemical current finally reaching a steady current, which implies electrochemical current equilibrated with the non-faradic current disappearing, and measure the steady current for calculating a specimen concentration.

Abstract
A method for fast measurement of a specimen concentration which needs a sensing strip with an electrode test region on which an enzymatic reagent with a specific ingredient is coated and has steps as follows: place a specimen on the electrode test region of the sensing strip; apply a high voltage on the electrode test region for a period to create electrochemical current therein by which at least a faradic current and at least a non-faradic current are generated in the electrode test region; apply a measuring voltage less than the high voltage or the same as the high voltage on the electrode test region to generate a total current including faradic and non faradic currents and the total current finally reaching a steady current, which is measured for calculating a specimen concentration.
