Abstract
A detection device is provided with a holder, light irradiation unit, signal detection unit, and processing unit. The holder holds a detection chip. The light irradiation unit irradiates light onto the detection chip held by the holder. When the light irradiation unit irradiates the detection chip with light, the signal detection unit detects, at least twice, a signal generated at a reaction site. The processing unit calculates a signal value variation rate on the basis of a first signal value detected by the signal detection unit and a second signal value detected after the first signal value.
Claims19
A detection apparatus configured to detect an analyte in a sample using a detection chip having a reaction site where a capturing body is immobilized, the apparatus comprising:
- a holder holding the detection chip;
- a light irradiation section irradiating the detection chip held by the holder with light;
- a signal detector detecting at least twice a signal generated in the reaction site when the light irradiation section irradiates the detection chip with light;
- and
- a processor calculating a change rate of signal values based on a first signal value detected by the signal detector and a second signal value detected after the first signal value.
A detection method for detecting an analyte in a sample using a detection chip having a reaction site where a capturing body is immobilized, the method comprising:
- providing the sample to the reaction site of the detection chip;
- obtaining a first signal value by irradiating the detection chip with light in a state in which the sample provided to the reaction site is removed, and detecting a signal generated in the reaction site;
- obtaining a second signal value after obtaining the first signal value by irradiating the detection chip with light and detecting a signal generated in the reaction site;
- and
- calculating a change rate of signal values based on the first signal value and the second signal value.
