Abstract:
1. A sample analyzer comprising: a sample preparing section comprising one or more chambers to prepare a measurement sample by mixing a part of a blood sample and a reagent therein: a first detector configured to detect electronic resistance of the measurement sample so as to detect platelets; a second detector comprising: a flow cell through which the measurement sample flows: a light emitting unit for irradiating light; and a light receiving unit for receiving light from the light emitting unit, so as to optically detect platelets; and a controller configured to perform operations, comprising: (a) controlling the sample preparing section to prepare a first measurement sample by mixing a first part of a blood sample and a first reagent, provide the first measurement sample to the first detector, prepare a second measurement sample by mixing a second part of the blood sample and a second reagent, and provide the second measurement sample to the second detector; (b) obtaining a first result, detected by the first detector, regarding platelets in the first measurement sample, and obtaining a second result, detected by the second detector, regarding platelets in the second measurement sample; (c) determining reliability of the first result and the second result; (d) when the first and second results have been determined to be unreliable, controlling the second detector to change a detection sensitivity of the light receiving unit; (e) controlling the sample preparing section to prepare a third measurement sample by using a third part of the blood sample, and provide the third measurement sample to the second detector; and (f) obtaining a third result, detected by the second detector, regarding platelets in the third measurement sample.
