Abstract:
Objective To investigate the application of “top-down” method in assessment of measurement uncertainty of bio-chemical detection indicators .Methods The assessment data of internal quality control and external quality and “top-down”method were used to assess the precision and accuracy of 26 biochemical indicators ,and the two variables above were combined to calculate the measurement uncertainty .Results Uncertainty of 18 biochemical indicators was compatible with the target uncertainty ,ac-counting for approximately 69 .2% of all assessment projects .Five indicators ,such as TBIL ,albumin ,CK ,calcium and magnesium , was not compatible with the target uncertainty ,accounting for approximately 19 .2% of all assessment projects .Conclusion The“top-down” method is effective and feasible for assessment of measurement uncertainty of biochemical detection indicators .
