Objective To evaluate the comparability of measurement results for coagulation factor Ⅷ (FⅧ) and factor Ⅸ (FⅨ) activity and the commutability of reference materials on different measurement systems.Methods The study was performed according to CLSI guideline EP30 and China health standard WS/T 356-2011.Clinical samples with different levels of F Ⅷ and F Ⅸ which covered over the clinical analytical range,five lots of homemade reference materials (F20140601-F20140605) and a coagulation reference material (SSCLOT4) provided by NIBSC were detected for FⅧ and FⅨ activity on three popular measurement systems in China,which including Stago STA-R Evolution,IL ACL TOP700 and Sysmex CA7000 automatic coagulation analyzers using supplementary reagents.The results between measurement systems were analyzed pairwise.To evaluate the comparability,the linear regression and the biases between the results of clinical samples from two measurement systems were calculated.The comparability was evaluated by the regression coefficient and the biases inside the acceptable range.After eliminated outliers from the results,linear regressions were run again and the 95% confidence intervals were calculated.The commutability of the homemade reference materials and NIBSC reference material were evaluated by comparing the results with the limits of the intervals.Results The ranges of FⅧ and FⅨ level of clinical samples were 0.5%-218.0% and 1.6%-156.5%,which covered the sample levels in routine work and fit the requirements for commutability evaluation.The square of correlation coefficients (R2) of measurement results of clinical samples for FⅧ and FⅨ activity assays were 0.89-0.94 and 0.81-0.93.The proportions of outliers were all less than 10%.The comparability of measurement results of FⅧ and FⅨ in different measurement systems was acceptable.According to the acceptable criteria for bias,the measurement results of 42,41 and 45 clinical samples for FⅧ and 44,42 and 41 clinical samples for FⅨ were used in the commutability evaluation for homemade reference materials and NIBSC reference material after deleting the outliers.The five lots homemade reference materials and NIBSC reference material were all within the 95% prediction intervals from the linear regression of clinical samples' results.Conclusions Good correlation and comparability are found for FⅧ assay and those for FⅨ assay are acceptable.All homemade reference materials and NIBSC reference material are commutable for the three measurement systems.
