Abstract: Disclosed is a measurement apparatus that includes: a measurement unit configured to measure a control sample for quality control; a display unit; and a processing unit configured to cause the display unit to display an input screen for setting an evaluation criterion used in the quality control, and, in the measurement apparatus, the processing unit causes the display unit to display a quality control result of a test item, based on the evaluation criterion and a measurement result of the control sample.

Abstract: A flow cytometer capable of easily and reliably providing flow cytometry results without requiring a special trained technician is provided. The flow cytometer 10 includes an input unit 60 that receives an input of information for specifying a measurement item, a condition selection unit 71 for selecting a measurement condition from among one or a plurality of measurement conditions corresponding to information for specifying the measurement item received by the input unit 60, and a measurement unit 65 having a flow cell 20 through which a particle-containing liquid containing particles in the sample passes, wherein the measurement unit 65 optically measures particles of the particle-containing liquid flowing through the flow cell 20 in accordance with the measurement condition selected by the condition selection unit 71.

Abstract: A sample testing system includes a sample analyzer that analyzes a particle in a sample, and an information processing apparatus that receives a result of an analysis on the sample from the sample analyzer. The information processing apparatus includes a controller, a display unit, and an input unit. The controller controls the display unit to display a screen including a reference-information display region for the result of the analysis on the sample and an input-value display region for a visual test to be performed on the sample with a microscope when retesting is determined as necessary, basing the result of the analysis on the sample. With the screen displayed, the controller receives a count value of the particle counted in the visual test on the sample, through the input unit, and controls the display unit to display the received count value in the input-value display region.
