Abstract: A sample analyzer comprises an input to select a sample type to be measured from a plurality of platelet sample types of differing concentrations, a measurement part to obtain optical information of a sample, a processing part that calculates platelet aggregation information from the optical information, and an alarm part. The processing part determines whether the actual measured sample type differs from the inputted sample type based on the optical information from the measurement part, and actuates the alarm part accordingly.

Abstract: A blood coagulation analyzing method according to one or more aspects may include: calculating a coagulation time based on data representing a coagulation curve of a change in an optical detection value of a blood specimen added with a reagent for starting a coagulation reaction; calculating an index value related to derivatives calculated concerning the coagulation curve represented by the data used in the calculating the coagulation time; and determining whether an early reaction error has occurred based on a comparison result obtained by comparing the index value to a predetermined threshold.
