Inspection devices and blood mixture diluted METHOD

Inspection device (40) includes an injection hole for introducing the blood sample (44a), in communication with the injection hole (44a) through a flow path (211A), and blood cell separation chamber for receiving a blood sample (41), soluble and a hemolysis chamber (42) for accommodating the blood. Inspection device (40), by being rotated and stopped around the rotational center, a blood sample which is contained in blood cell separation chamber (41) separated into blood cells and plasma fluid, blood cell separation chamber (41), flow path flow path integration region via a (211B) and (43) is communicated with, the plasma liquid separated from the blood sample is transported through a flow path (211B), plasma hemolysate in the through channel integrated regions It is mixed and diluted with liquid and a predetermined dilution ratio.
