  • the component analysis using the image in the analyzer 20 is performed on one or more types of component in the component analysis by flow cytometry input from the analyzer 30. It is executed on condition that the measurement result is out of the reference range. In other words, if the measurement result of all the formed components is within the reference range in the formed component analysis by flow cytometry, the formed component analysis using the image in the analyzer 20 is not executed.
  • the analysis system 1 includes the analysis device 10 that performs urine qualitative analysis in addition to the analysis device 30 and the analysis device 20, the analysis device 20 may change the conditions for performing the tangible component analysis using the image. Good. That is, the analysis device 20 may perform the formation analysis when the result of at least one kind of formation is inconsistent with the result of the qualitative analysis by the analysis device 10 in the formation analysis by the analysis device 30. Good.
  • the analyzer 20 does not execute the component analysis if the measurement result of all the components in the component analysis by the analyzer 30 matches the result of the qualitative analysis by the analyzer 10.
