FLOW CYTOMETER AND METHOD FOR MEASURING SAMPLE

Provided is a flow cytometer with which it is possible to obtain the concentration of an object to be measured in a measurement sample without using a standard sample. The present invention provides a flow cytometer comprising a flow cell, a sample supply unit for supplying, to the flow cell, a prescribed amount of a measurement sample prepared by mixing a specimen containing an object to be measured and a labeled antibody that binds to the object to be measured, and a light source for irradiating the measurement sample that has passed through the flow cell with light, a detection unit that detects light derived from an object to be measured contained in the measurement sample irradiated with the light and outputs a signal, and an analysis unit that counts the object to be measured contained in the measurement sample on the basis of the signal and acquires the concentration of the object to be measured on the basis of the counted number of the object to be measured and the specified amount. 本发明提供不使用标准试样也能得到测定
