Abstract: Disclosed is a blood sample determination method including: emitting light to a measurement specimen prepared by mixing a clotting time measuring reagent and a blood sample suspected to be derived from a subject having lupus anticoagulant or a coagulation factor inhibitor, to obtain optical information about an amount of light from the measurement specimen; obtaining at least one parameter regarding derivative of clot waveform, based on the obtained optical information; and determining, based on a value of the obtained parameter, whether the blood sample is suspected to be a sample derived from a subject having lupus anticoagulant or is suspected to be a sample derived from a subject having a coagulation factor inhibitor.

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.

Abstract: A sample analyzer comprises a container setting part on which a liquid container is to be set, a liquid supplying part configured to supply a liquid to the liquid container, an aspiration tube configured to aspirate a sample or a reagent, a movement mechanism configured to move the aspiration tube, a liquid surface sensor configured to detect contact of the aspiration tube with a liquid surface, and a controller configured to execute an aspiration tube adjustment operation. The aspiration tube adjustment operation comprises supplying the liquid to the liquid container by the liquid supplying part, lowering the aspiration tube by the movement mechanism toward the liquid container set on the container setting part, and obtaining information regarding a position in a height direction of the aspiration tube at a time when the aspiration tube has come into contact with the liquid surface.

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.
