Abstract

This invention discloses a detachable test strip good for multiple tests on one strip to reduce the cost of test strip per test, and a test strip with more than two electrodes for the simultaneous measurement of more than one biological data with one drop of blood only.

Claims

1. A test strip with several detachable test pieces, comprising of:

a) a test strip with pre-cut under the base strip ready to be broken off after use, with conductive electrodes and reagents laid on the surface thereof;

b) a test strip with a plurality of thin film of test piece on the base strip, attached with conductive electrodes and reagents. After a layer of thin film is done with test, it will be peeled off for another fresh thin film with reagents and electrodes.

2. A test strip with more than two conductive electrodes for simultaneous measurement of multiple biological tests, comprising of:

a) three electrodes for the measurement of two different reagents, with the central electrodes serving as the ground reference electrodes;

b) four electrodes for measuring two different reagents, with two electrode for one regent;

c) four electrodes for measuring three different reagents, with one electrode serving as ground reference electrode;

d) six electrodes for measuring three different reagents, with no electrode serving as ground reference electrode;

e) more than six electrodes for the measurement of more than three reagents.

3. A test strip with multi-layered electrodes for the simultaneous measurement of several biological tests, comprising of:

a) one or more than one layer of two conductive electrodes with base strip, on which are embedded with one or more than one reagents, stacked together with glue or firmly bonded by ultrasonic device;

b) a test strip with one or more than one pre-cuts ready to be broken off or cut off after every use.
