A method of determining an analyte in a sample utilizing a redox reaction is provided, by which a highly reliable determined value can be obtained. In this method, a tetrazolium compound is added to a sample in the presence of a surfactant prior to a redox reaction so as to eliminate an effect of hemoglobin and a hemoglobin degradation product as reducing substances in the sample.

Then, the amount of the analyte in the sample is determined based on the amount of the reducing or oxidizing substance thus determined. According to this method, cloudiness due to the coexistence with the hemoglobin can be prevented by the surfactant and thus an increase in the absorbance due to the cloudiness can be inhibited as shown in FIG. 1. As the surfactant, polyoxyethylene ether and the like can be used.

An integrated circuit includes a plurality of processing stages each including processing logic 1014, a non-delayed signal-capture element 1016, a delayed signal-capture element 1018 and a comparator 1024. The non-delayed signal-capture element 1016 captures an output from the processing logic 1014 at a non-delayed capture time. At a later delayed capture time, the delayed signal-capture element 1018 also captures a value from the processing logic 1014. An error detection circuit 1026 and error correction circuit 1028 detect and correct random errors in the delayed value and supplies an error-checked delayed value to the comparator 1024. The comparator 1024 compares the error-checked delayed value and the non-delayed value and if they are not equal this indicates that the non-delayed value was captured too soon and should be replaced by the error-checked delayed value. The non-delayed value is passed to the subsequent processing stage immediately following its capture and accordingly error recovery mechanisms are used to suppress the erroneous processing which has occurred by the subsequent processing stages, such as gating the clock and allowing the correct signal values to propagate through the subsequent processing logic before restarting the clock. The operating parameters of the integrated circuit, such as the clock frequency, the operating voltage, the body biased voltage, temperature and the like are adjusted so as to maintain a finite non-zero error rate in a manner that increases overall performance.
