Sample analyzer and sample analyzing method

A sample analyzer comprising:

• a first measurement unit configured to measure a sample on a first measurement item;
• a second measurement unit configured to measure a sample on the first measurement item and a second measurement item;
• a controller;
• and
• a transport unit configured to transport a sample rack which holds a plurality of samples in a transport direction from a before-analysis rack holding section to an after-analysis rack holding section,
• wherein a first sample is designated the first measurement item and is not designated the second measurement item,
• wherein a second sample is designated the first measurement item and second measurement item,
• wherein the controller is programmed to control the transport unit to transport separately first samples to the first measurement unit and the second measurement unit, when the sample rack holds a plurality of first samples,
• wherein the controller is further programmed to control the transport unit to transport the second sample to the second measurement unit without transporting the first sample to the second measurement unit based on a measurement item of the second sample, when (a) the first measurement unit is not configured to accept either the first sample or the second sample based on a state of a first measurement unit state data area, (b) the second measurement unit is configured to accept either the first sample or the second sample based on a state of a second measurement state data area, and (c) the sample rack holds:
• the first sample;
• and the second sample at more upstream side in the transporting direction than the first sample.
