Biological sample analyzer, biological sample analysis system, and method for verifying status of biological sample analyzer

A biological sample analysis system comprising:

• an information processing unit configured to perform information processing using signal intensity data on light generated by irradiating a flow channel through which particles are flowing with light, wherein
• the information processing unit performs a data replacement step of replacing signal intensity data on light generated by irradiating, with light, any one type of particle group in a data set of signal intensity data on light generated by irradiating, with light, a sample containing a plurality of types of particle groups, the plurality of types of particle groups having varying fluorescence intensity levels, with signal intensity data acquired by irradiating, with light, the flow channel through which no particles are flowing, in verification processing of verifying a status of a device.

A method for verifying a status of a biological sample analyzer, the method comprising:

• a data replacement step of causing a sample containing a plurality of types of particle groups having varying fluorescence intensity levels to flow into a flow channel, and replacing signal intensity data on light generated by irradiating, with light, on any one type of particle group in a data set of signal intensity data on light generated by irradiating, with light, particles flowing through the flow channel with signal intensity data acquired by irradiating the flow channel through which no particles are flowing with light.
