Test chip and test chip system

摘要

A test chip (30) which allows a number of solution delivery steps much faster and accurate is provided. The test chip incorporates a sample flow path (4) for containing a sample solution, a reaction flow path (2) for inducing a predetermined reaction with the sample solution, a waste drain path (3) for receiving the used sample, and the washing solution flow paths (5-8) for containing washing solutions. The reaction flow path contains a plurality of beads (1) having probes of mutually different types fixed thereon. The sample flow path, washing solution flow paths, and sample waste drain path have their respective solution detector units (3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b). The solution detector unit detects whether the solution is fed to the path. The detector units adjoiningly provided in the adjacent paths are arranged collinearly.
