Microchip and liquid mixing method and blood testing method using this microchip

摘要

A microchip comprises: a flow path substrate; an inlet port; a flow path adapted to cause a plurality of kinds of liquid to flow while mixing the plurality of kinds of liquid; and a decompression port configured to communicate with the flow path and to be connectable to a decompression unit, wherein the flow path includes a first flow path portion and a second flow path portion provided so that they are alternately formed, and wherein the first flow path portion has a larger cross-sectional area than the flow path portion other than the first flow path portion, and wherein the second flow path portion has a smaller cross-sectional area than the first flow path portion; and a blood test method comprises: mixing a blood with a dilute solution by utilizing the microchip described above.
