PROBLEM TO BE SOLVED: To provide a method of manufacturing a chip using a disposable, low-priced substrate, a method of correcting a measurement error caused by a time-varying change in a detecting system by mixing blood plasma or blood serum with a buffered liquid substrate or coloring liquid in a microchip, and a method of confining illuminating light completely within a micro flow channel without leakage into the outside. SOLUTION: A painless needle for blood collection on the chip, a U-shaped capillary for isolating blood cells, blood plasma, or blood serum, the micro flow channel for blood plasma or blood serum and a reagent, a mixer using centrifugal force, and an optical path for light are arranged. Using a small amount of blood, the concentrations ofγ-GTP. GOT, and GOT can be measured in a short time. For the miniaturization and price-reduction of the apparatus, a cell inlet, the flow channel, a branched flow channel, and a pumping means are integrally on the chip, and as the pumping means, an electroosmatic flow pump is used which does not directly apply an electric field to cells.
