To provide a sample analyzer capable of accurately obtaining the number of analyzable samples. When analyzing a sample collected from a subject, a CPU of the sample analyzer calculates the number of analyzable samples based on a remaining number of tests of a reagent set in a reagent holding section and the number of tests of the reagent to be consumed in measurement of a control, and causes a output section to display the number of analyzable samples. When creating a calibration curve, the CPU calculates the number of analyzable samples based on a remaining number of tests of the reagent set in the reagent holding section, the number of tests of the reagent to be consumed in measurement of the control, and the number of tests of the reagent to be consumed in measurement of a calibrator, and causes the output section to display the number of analyzable samples.
