  Generally, since the time required for one test is about 10 minutes (10-minute reaction), the result of 300 tests is output in 10 minutes. Therefore, since the presence or absence of retesting of the sample sampled first when the sampling for 300 tests is completed is determined, 10 racks of sample racks 50 are mounted on the movable conveyor unit 201 of the initial testing / retesting sampling lane 200. It only has to be placed.
