Embodiment Construction
[0034] The present invention will be further described below.
[0035] An enzyme electrode biosensor anti-interference assay method, comprising the steps of:
[0036] In the case that there is an enzyme activity inhibitor in the determination substrate, the calibration of the enzyme activity is also carried out in the same environment, so that the calibration and determination status are in the same enzyme reaction environment. The influence of enzyme activity inhibitors on the determination process was excluded. In the measurement process, the sample to be tested is directly injected according to the set injection volume (nμl), and the response current value of the enzyme electrode sensor to the sample is measured, and repeated several times until the response current value of the sensor is basically unchanged (less than the set error value), record the average value X of the response current measured for the last two times (or the last response current value, taking the las...
