A system comprising a sample analyzer which transports a rack holding a plurality of sample containers and analyzes samples and a rack, the sample analyzer comprising: a first measurement apparatus which measures samples; a second measurement apparatus which is arranged downstream, in a transport direction, from the first measurement apparatus, and which measures samples; and a transporting apparatus which transports samples to a first supply position for supplying a sample to the first measurement apparatus, and to a second supply position for supplying a sample to the second measurement apparatus, wherein the transporting apparatus linearly transports the rack from the first supply position to the second supply position, the sample analyzer further comprising: determination means (121a, 301, 401) which determines, based on a measurement result obtained by the first measurement apparatus, whether measurement by the second measurement apparatus is necessary, wherein until the determination means determines whether measurement by the second measurement apparatus is necessary, the transporting apparatus does not transport a sample for which the determination is made, to downstream from the second supply position, wherein the first measurement apparatus is a urine qualitative measurement apparatus and the second measurement apparatus is a urinary sediment measurement apparatus, the system being characterised in that a distance between the first supply position and the second supply position is a multiple of a distance between adjacent sample containers held in the rack, and in that the distance between the first supply position and the second supply position is shorter than or equal to a distance from a sample container held in the rack at one end thereof to a sample container held in the rack at the other end thereof. a first measurement apparatus which measures samples; a second measurement apparatus which is arranged downstream, in a transport direction, from the first measurement apparatus, and which measures samples; and a transporting apparatus which transports samples to a first supply position for supplying a sample to the first measurement apparatus, and to a second supply position for supplying a sample to the second measurement apparatus, wherein the transporting apparatus linearly transports the rack from the first supply position to the second supply position, the sample analyzer further comprising: determination means (121a, 301, 401) which determines, based on a measurement result obtained by the first measurement apparatus, whether measurement by the second measurement apparatus is necessary, wherein until the determination means determines whether measurement by the second measurement apparatus is necessary, the transporting apparatus does not transport a sample for which the determination is made, to downstream from the second supply position, wherein the first measurement apparatus is a urine qualitative measurement apparatus and the second measurement apparatus is a urinary sediment measurement apparatus, the system being characterised in that a distance between the first supply position and the second supply position is a multiple of a distance between adjacent sample containers held in the rack, and in that determination means (121a, 301, 401) which determines, based on a measurement result obtained by the first measurement apparatus, whether measurement by the second measurement apparatus is necessary, wherein until the determination means determines whether measurement by the second measurement apparatus is necessary, the transporting apparatus does not transport a sample for which the determination is made, to downstream from the second supply position, wherein the first measurement apparatus is a urine qualitative measurement apparatus and the second measurement apparatus is a urinary sediment measurement apparatus, the system being characterised in that a distance between the first supply position and the second supply position is a multiple of a distance between adjacent sample containers held in the rack, and in that the distance between the first supply position and the second supply position is shorter than or equal to a distance from a sample container held in the rack at one end thereof to a sample container held in the rack at the other end thereof.
