Measurement method and measurement device

A measurement method, comprising:

• a first reaction step of reacting a detection substance with a first reaction substance which reacts specifically with each of the detection substance and a first correction substance;
• a second reaction step of reacting the first correction substance with the first reaction sub stance;
• a first measurement step of measuring a first signal value derived from a reaction between the detection substance and the first reaction substance;
• a second measurement step of measuring a second signal value derived from a reaction between the first correction substance and the first reaction substance;
• and
• a correction step of correcting the first signal value with use of the second signal value,
• the second reaction step and the second measurement step being carried out prior to the first reaction step or subsequent to the first measurement step.

A measurement method, comprising:

• a first reaction step of reacting a detection substance with a first reaction substance which reacts specifically with the detection substance;
• a second reaction step of reacting a second reaction substance with a correction substance which specifically reacts at least with the second reaction substance;
• a first measurement step of measuring a first signal value derived from a reaction between the detection substance and the first reaction substance;
• a second measurement step of measuring a second signal value derived from a reaction between the second reaction substance and the correction substance;
• and
• a correction step of correcting the first signal value with use of the second signal value.

A measurement device, comprising:

• a detecting section on an upper surface of the measurement device on which a reaction substance that can react specifically with a detection substance and a correction substance is placed, and which can measure signal values based on reactions of the reaction substance;
• a supply section which supplies the detection substance and the correction substance to the detecting section;
• a measurement section which measures a first signal value of the signal values based on a reaction between the detection substance and the reaction substance, and a second signal value of the signal values based on a reaction between the correction substance and the reaction substance;
• and
• a correction section which corrects the first signal value using the second signal value.

A measurement device, comprising:

• a first reaction section which reacts a detection substance with a first reaction substance which reacts specifically with the detection substance;
• a second reaction section which reacts a correction substance with a second reaction substance which specifically reacts at least with the correction substance;
• a measurement section which measures a first signal value derived from a reaction between the detection substance and the first reaction substance, and a second signal value derived from a reaction between the correction substance and the second reaction substance;
• and
• a correction section which corrects the first signal value with use of the second signal value.
