ABSTRACT:
Buffer solution and blood are streamed in a channel of a micro chip so as to form layers. Aggregation inducing agent for aggregating platelets in blood is coated at a wall face on a buffer solution streaming side. If streaming amount of blood is increased in this state, a layer width of blood can be increased, and detail analysis between the aggregation inducing agent and the platelets is possible thereby. Even if it is necessary to take an image or a moving image for comparison between a pre-aggregation state and an aggregation state, it is sufficient to take only a portion where the aggregation inducing agent is coated, that is, a reaction portion. Then, a device can be made cheaper without two cameras or a moving mechanism for the camera or a micro chip.
