Abstract
Objective To evaluate the performance of Mindray BC‐5390 CRP hematology and CRP all‐in‐one analyzer .Methods The evaluation experiments included background ,blank count ,carryover ,repeatability ,CRP line‐arity ,the correlation of hematology parameters with Sysmex XN‐9000 ,the correlation of CRP results with Beckman Coulter Immage 800 ,the correlation of CRP results from different modes ,the stability of CRP results and the inter‐ference test of different sample types .Results The results of background ,blank count and carryover are met the re‐quirements manufacturer′s claim .Main parameters of hematology and CRP had fine precision and repeatability ,The CV% were less than 2 .00% .The CRP had good linearity between 0 .2 and 320 mg/L .Main parameters of hematolo‐gy had good correlation with Sysmex XN‐9000 ,all CBC parameters were higher than 0 .980 0 and all correlation coef‐ficients of WBC differential parameters except Bas% were higher than 0 .950 0 .The correlation coefficients of BC‐5390 CRP and Immage 800 was 0 .995 3 and the correlation coefficients between different mode were higher than 0 .990 0 .The results were relatively stable from samples stored in low temperature for 48 hours and samples stored in room temperature for 24 hours .There were no interference of all abnormal samples when we did abnormal sample in‐terference tests except two CRP results from highest value RBC samples(>8 .0 × 1012/L) had bigger difference when compared with control analyzer .Conclusion The overall performance of BC‐5390 CRP is excellent and it can meet the requirements of clinical application .Thus ,BC‐5390 CRP is a perfect blood tests and CRP all‐in‐one analyzer .关键词
