A sample-test-device management server adapted to be coupled with a sample test device via a network, the sample-test-device management server comprising: a storage unit which stores a plurality of sample prior-process-policy determination tables, each for determining a policy of accepting a prior process request, wherein each of the plurality of sample prior-process-policy determination tables defines a correspondence between a plurality of different prior process policies and different combinations of a process state of the sample and a priority of the sample, and wherein the plurality of sample prior-process-policy determination tables are each different from each other; and a processing unit, wherein when a sample prior process request containing information indicating a sample ID and a prior-process-request level identification code is received, said sample prior process request specifying a sample from a plurality of samples, each of which has an allocated priority, the processing unit is configured to: select one of the plurality of sample prior-process-policy determination tables based on the prior-process-request level identification code indicated in the information contained in the sample prior process request; determine a prior process policy for a sample corresponding to the sample ID based on the selected one of the plurality of sample prior-process-policy determination tables, a process state (901, 903, 905) of said sample, and a priority (902, 904, 906) of said sample, and transmit information indicating the determined prior process policy for said sample to the sample test device. a storage unit which stores a plurality of sample prior-process-policy determination tables, each for determining a policy of accepting a prior process request, wherein each of the plurality of sample prior-process-policy determination tables defines a correspondence between a plurality of different prior process policies and different combinations of a process state of the sample and a priority of the sample, and wherein the plurality of sample prior-process-policy determination tables are each different from each other; and a processing unit, wherein when a sample prior process request containing information indicating a sample ID and a prior-process-request level identification code is received, said sample prior process request specifying a sample from a plurality of samples, each of which has an allocated priority, the processing unit is configured to: select one of the plurality of sample prior-process-policy determination tables based on the prior-process-request level identification code indicated in the information contained in the sample prior process request; determine a prior process policy for a sample corresponding to the sample ID based on the selected one of the plurality of sample prior-process-policy determination tables, a process state (901, 903, 905) of said sample, and a priority (902, 904, 906) of said sample, and transmit information indicating the determined prior process policy for said sample to the sample test device. select one of the plurality of sample prior-process-policy determination tables based on the prior-process-request level identification code indicated in the information contained in the sample prior process request; determine a prior process policy for a sample corresponding to the sample ID based on the selected one of the plurality of sample prior-process-policy determination tables, a process state (901, 903, 905) of said sample, and a priority (902, 904, 906) of said sample, and transmit information indicating the determined prior process policy for said sample to the sample test device.
