Centrifugal blood component separator is widely used in clinical practice,and the accuracy of its parameters directly affect the health and safety of patients.According to industry standards and equip-ment technical principles,it can determine the main measurement characteristics in metrology and spe-cific calibration methods,and then select products of representative brand for verification.Finally,the measurement characteristics of the centrifugal blood component separator are verified according to the cal-ibration method,and the verification results meet the requirements of the determined measurement char-acteristics.The development of this calibration specification can provide a technical basis for the traceabil-ity of the measurement value of the centrifugal blood component separator.
