Abstract:
Objective To perform the comparative analysis on the use situation of 3 kinds of dry chemical analyzers according to the industrial standards YY/T0655-2008.Methods With the Roche Cobas P800 automatic biochemical analyzers as the reference instrument,the accuracy,intra-assay precision,linearity,etc.in 3 kinds of dry chemical analyzers were evaluated.Results 3 kinds of dry chemical analyzers met the requirements of the industrial standards YY/T0655-2008,but the precision of imported instrument was significantly better than that of the domestic instrument.Conclusion In order to ensure the comparability and consistency of the detection results among instruments,the instruments should be regularly calibrated and performed the comparative experi-ments,the premise of calibration and comparison should be using 1/4 of the precision level in the CLIA′88 indicators as the indica-tor,not satisfying with the precision requirements in YY/T0655-2008,only in this way can the waste of blood and donors going a-way be avoided.
