Disclosed is a specific binding analysis method capable of controlling the amount of specific binding to freely setting the sensitivity, concentration range and the like in an analysis, and a device used therefor. A wireless transmission section transmits a transmission signal including the acquired intra-subject information to an extracorporeal receiving apparatus provided outside the subject. In one aspect of this form, the wet film is a narrow, continuous stripe of reagent material applied to a moving web of the substrate from which a plurality of test elements will be obtained. The power controller is configured to output the relay control signal input to the lighting relay and the emergency relay control signal input to the emergency relay to control the operation of the lighting load and the emergency lighting load respectively. The read suspension can be conditioned upon one or more predefined criteria, such as a disk bandwidth threshold being satisfied, a time since a last request threshold being satisfied and a condition that only a request for a different stream than a currently requested stream is suspended.
