To examine γ-GTP, GOT, and GPT, which are conventional indices for examining liver function in humans, a large amount of blood is collected, a large-sized and expensive device is used, and it takes time. Kind Code: A1 Abstract: A painless needle for collecting blood, a U-shaped capillary for separating blood cells, plasma or serum, a fine channel for plasma or serum and a reagent, a mixer using centrifugal force, and an optical path of light are arranged on a chip. Thus, it was possible to measure the concentrations of γ-GTP, GOT, and GPT from a small amount of blood in a short time. In order to reduce the size and cost of the device, the cell introduction port, flow path, branch flow path and pump means are formed on an integrated chip, and in particular, the pump means does not directly apply an electric field to the cells. Use an osmotic pump. [Selection diagram] FIG. |
