Bias analysis on the results of bilirubin among different analysis systems
2007
Objective:To study the comparability on the results of bilirubin among different analysis systems.Methods:With the analysis system 1 with the Hitachi7170 A biochemical analyzers,Roche reagent and program,Roche c-fas calibration as a target system and detecting systems 2 and 3 as comment system,the total and direct bilirubin were analysed in 45 patient fresh sera and 2 levels of Randox controls.Results:Analysis of variance showed that the results of total bilirubin(TBIL)and direct bilirubin(DBIL) from RANDOX controls and patient sera had significant difference between system 1 and system2 or 3,and also the correlation coefficient was all above 0.975.The result of TBIL in system 2 was partly exceeded T±10%,the other results were all exceeded T±10%.Conclusion:The results of TBIL and DBIL in three analysis systems were incomparability.
