The verification of this analyzer is essential to meet the ISO15189 standard. Methods: Analytical performance was evaluated according to the NCCLS EP05-A method. The results of plasma samples were compared between the SBA and a Hitachi 917 analyzer according to the NCCLS EP09-A2-IR method. Percent recovery was determined via analysis of original control serum and spiked serum. Results: Within-run precision was found to be 0.00-6.61% and 0.96-5.99% in normal- and abnormal-level assays, respectively, while between-run precision was 1.31-9.09% and 0.89-6.92%, respectively. The correlation coefficients (r) were > 0.990. The SBA presented analytical accuracy at 96.64 ± 3.39% to 102.82 ± 2.75% and 98.31 ± 4.04% to 103.61 ± 8.28% recovery, respectively. Conclusions: The results obtained verify that all of the 13 tests performed using the SBA demonstrates good and reliable precision suitable for use in qualified clinical chemistry laboratory service.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyArticleSCOPUS10.7754/Clin.Lab.2012.120705
