Problems solved by technology
When using this test strip to test, the required blood sample volume is relatively large, usually no less than 3-4 microliters, so the method of pricking a finger with a needle must be adopted to meet the requirements of a large sample volume, which often causes blood test problems. At the same time, because it has only one enzyme reaction zone, the test results are often interfered by other reducing substances in the blood sample, red blood cells and blood viscosity, which will cause deviations in the test results, thus affecting the accuracy and accuracy of the test results. Reproducibility, in addition, because the area of the working electrode is larger than that of the reference electrode, the stability of the test is poor

Embodiment Construction
[0019] From figure 1 It can be seen that the test strip of the present invention is provided with two reaction zones on the substrate 1, one is an enzyme reaction zone 2, and the other is a non-enzyme reaction zone 5, these two reaction zones are adjacent, and the bottom is separated by an isolation strip 7 , and there are working electrode 3 and working electrode 6 respectively, the two areas are equal, the reference electrode 4 is the common electrode of the two, and its area is larger than the working electrode (one), we can see from the figure that these three electrodes are connected directly The lower end of the test strip, which is the connection port between the test strip and the tester.

Abstract
The test strip for testing biochemical matter in blood includes one insulating substrate, one enzyme reaction area on the substrate, work electrode and reference electrode with one end connected to the enzyme reaction area and other end connected to the test instrument, and one non-enzyme reaction area adjacent to the enzyme reaction area with also work electrode and reference electrode connected. The enzyme reaction area and the non-enzyme reaction area are separated with a separating band in the bottom and covered with one covering sheet to form one blood sucking passage with side port. Compared with available technology, the test strip has the advantages of high test accuracy, high test repeatability and micro sampling design.
Description
Technical field: [0001] The present invention relates to a test strip for testing biochemical substances in blood and its production method Background technique: [0002] The test strip currently used for testing biochemical substances in blood consists of a substrate, an enzyme reaction zone on the substrate, a working electrode connected to the enzyme reaction zone at one end, and a working electrode and a reference electrode connected at the other end to a tester. When using this test strip to test, the required blood sample volume is relatively large, usually no less than 3-4 microliters, so the method of pricking a finger with a needle must be adopted to meet the requirements of a large sample volume, which often causes blood test problems. At the same time, because it has only one enzyme reaction zone, the test results are often interfered by other reducing substances in the blood sample, red blood cells and blood viscosity, which will cause deviations in the test resu...
