Objective 　To study the comparability of liver function results between the two detection systems.
Methods 　Based on the NCCLS EP9-A document, 8 fresh serum samples were collected daily for the assay of 10 routine liver function parameters by utilizing the Olympus AU1000 and Backman CX7 detection systems respectively. The results were recorded over 5 days consecutively. Linearity equation and relative deviations were calculated. The comparability between the results obtained from different detection systems was evaluated according to the systematic error at medical decision level of CLIA, 88.
Results 　The paired t-test showed that the results of the fresh serum samples had no significant difference between the two detection systems (P gt;0.05). Except that the systematic error of albumin at low medical decision level exceeded the allowable error, all the other systematic errors at medical decision level were acceptable.
Conclusion 　The results of liver function are comparable between the two detection systems, and the systematic errors between the two detection systems are clinically acceptable.
