drawing in detail fig1 is a schematic view of the detachable test strips with two conductive electrodes good for performing three tests but there will be one reading per test only as a drop of blood is added to the dashed circular area for reagents 36 of the strip 10 the pre embedded reagent 36 reacts electrochemically with the blood to produce an electric current which will be measured through the conductive electrodes to determine the biological readings of interest in the blood after a test is done with the test the tested section can be easily broken off from the dashed line 11 which has a pre cut across the width of the test strip 10 on the opposite side of the test strip 10 as shown in fig2 fig2 also shows the composition of the electrodes as one layer of conductive silver 21 on top of which lies a layer of conductive carbon reagents 36 are placed on top of the carbon electrode fig3 shows the schematic view of the drawings of the detachable test strips with three electrodes good for performing three tests but there will be two test readings per test reagent 361 is different from reagent 362 to produce two different biological test data with one drop of blood which could cover very well both regents 361 and 362 the central electrode 201 serves as the ground reference electrode for the neighboring electrodes 202 and 203 fig4 further discloses the schematic view of the detachable test with four electrodes good for three tests per strip but two test reading per test electrodes 204 and 205 are used to measure one reaction just like electrodes 206 and 207 in order to perform three different measurement on one test piece there are two.
