A specimen processing system comprising: an input buffer module which is configured to input a sample into the system; a centrifuge module capable of holding plural adapters with samples loaded thereon and capable of performing centrifugal processing simultaneously on the samples held on the adapters; a first sample identification unit which is a sample input monitoring unit for monitoring input of a sample into the input buffer module; a second sample identification unit which is a sample arrival monitoring unit which monitors arrival of a sample at the centrifuge module; wherein the first sample identification unit and the second sample identification unit are provided on a sample conveying line and are configured to identify a sample; a centrifuge set setting unit which is configured to set a group of samples identified by the first or second sample identification unit on which centrifugal processing is simultaneously performed by the centrifuge module, as a centrifuge set; a sample shifting unit which is configured to shift a sample of a finalized centrifuge set, to the adapters on which centrifugal processing is performed simultaneously by the centrifuge module; an attribute discrimination unit which is configured to discriminate an attribute of a sample identified by the first or second sample identification unit, wherein the attribute discrimination unit is configured to discriminate sample attributes including a routine sample and a STAT sample; and a time-out determination unit which is configured to set a time-out time with respect to the centrifuge set setting unit on the basis of the discriminated attribute of the sample, wherein the time-out determination unit is configured to set a time-out time for the STAT sample to be shorter than for the routine sample; wherein if a next sample is not identified by the first or second sample identification unit (31, 70) even after the lapse of the time-out time set by the time-out determination unit, the centrifuge set that is set by the centrifuge set setting unit is finalized by the centrifuge set setting unit. an input buffer module which is configured to input a sample into the system; a centrifuge module capable of holding plural adapters with samples loaded thereon and capable of performing centrifugal processing simultaneously on the samples held on the adapters; a first sample identification unit which is a sample input monitoring unit for monitoring input of a sample into the input buffer module; a second sample identification unit which is a sample arrival monitoring unit which monitors arrival of a sample at the centrifuge module; wherein the first sample identification unit and the second sample identification unit are provided on a sample conveying line and are configured to identify a sample; a centrifuge set setting unit which is configured to set a group of samples identified by the first or second sample identification unit on which centrifugal processing is simultaneously performed by the centrifuge module, as a centrifuge set; a sample shifting unit which is configured to shift a sample of a finalized centrifuge set, to the adapters on which centrifugal processing is performed simultaneously by the centrifuge module; an attribute discrimination unit which is configured to discriminate an attribute of a sample identified by the first or second sample identification unit, wherein the attribute discrimination unit is configured to discriminate sample attributes including a routine sample and a STAT sample; and a time-out determination unit which is configured to set a time-out time with respect to the centrifuge set setting unit on the basis of the discriminated attribute of the sample, wherein the time-out determination unit is configured to set a time-out time for the STAT sample to be shorter than for the routine sample; wherein if a next sample is not identified by the first or second sample identification unit (31, 70) even after the lapse of the time-out time set by the time-out determination unit, the centrifuge set that is set by the centrifuge set setting unit is finalized by the centrifuge set setting unit.
