Sample measurement device, sample measurement method, and sample measurement program

A sample measurement method, comprising:

• a voltage application step of applying voltage to an electrode unit in a state in which the electrode unit including at least a working electrode, a counter electrode, and a reference electrode of a sample measurement sensor is immersed in a sample;
• a current measurement step of measuring a current flowing through the sample measurement sensor by the voltage applied in the voltage application step;
• a concentration measurement step of calculating a concentration of an analyte contained in the sample on the basis of a measurement result in the current measurement step;
• a counter electrode terminal voltage measurement step of measuring a terminal voltage of the counter electrode included in the electrode unit in a state in which voltage is being applied in the voltage applying step;
• and
• a measurement error detection step of detecting a measurement error on the basis of the terminal voltage of the counter electrode measured in the counter electrode terminal voltage measurement step,
• wherein the measurement error detection unit detects a contamination error attributable to an admixture of an impurity other than the analyte.
