Abstract:
1. A blood analysis apparatus comprising: a driving unit comprising: a measuring unit comprising: a controller which controls the rotation driving mechanism, the light source, and the light-receiving unit, wherein the controller comprises a measurement position setting part which determines a measurement position of the rotary body at which the measurement liquid is to be measured with the light from the light source, wherein, before the measurement liquid is measured, the measurement position setting part controls the rotation driving mechanism to rotate the rotary body in a state that the chip holding portion is fixed relative to the rotary body such that the chip holding portion is not rotated with respect to the rotary body and sets a rotational position of the rotary body where a light value of the light received by the light-receiving unit through the aperture is a threshold value or more, as the measurement position, and wherein the measurement position setting part determines the measurement position after heating the chip holding portion until an ambient temperature thereof reaches a certain temperature.
