Objective:
To estimate the consistency of two VITROS 3600 chemiluminescent analyzers according to the requirement of ISO15189.
Methods:
Verification tests were made for precision and accuracy of anti-HCV in two instruments. While 40 serum samples including Anti-HCV negative (10 cases) , positive (10 cases) , and weakly positive (20 cases). and the test results were statistical analised.
Results:
Two instruments negative and positive control samples intra-batch precision and coefficients of variation were 5% , 4% and 7. 14% , 7. 23% , inter-batch precision and coefficients of variation were 9. 47% , 7. 7% and 8.04%, 7. 6%, are less than requirement CV (15%) by ISO15189. The accuracy of two instrument were 100% , The test results of the control samples showed no significant difference (P < 0. 05). The correlation analysis of the test results of clinical samples R2 =0. 9984, with good consistency.
Conclusion:
Test results of two Vitros 3600 has good consistency and comparability.
