ABSTRACT
Objective To evaluate the comparability of the detection results of different blood cells analysis systems in same hos-pital.Methods Referring to the Guideline for Comparability Verification of Quantitative Test Results in Medical Institutions,the comparability validation protocol was established.The EDTA-K2 anticoagulation fresh whole blood samples with proper concentra-tion were detected for 5 parameters of HGB,RBC,HCT,PLT and WBC by 4 systems (Sysmex XT-1800i,Sysmex XT-2000,Sys-mex XT-4000i and Mindray BC-5800).The range was calculated and the detection results consistency analysis was performed.Re-sults The acceptable standard of critical differentials was intended to be HGB3.5%,RBC3%,HCT3%,PLT12.5% and WBC 7.5%.The replication detection was at least 2 times and up to 5 times.The ranges of 3 concentrations after replication detection and sample comparison were 2.87%-6.29%,1.57%-2.99%,1.95%-4.77%,12.81%-25.74% and 6.72%-11.13% respective-ly.The ranges of RBC detection results in 4 systems were smaller than the critical differentials,the validation was passed.The ran-ges of HGB,HCT,PLT and WBC detection results in 4 systems all had the condition of more than the critical differentials,the vali-dation did not passed.After removing the test system with obvious bias,the validation of the detection results by other test systems was passed.Conclusion The RBC detection results by 4 systems have the comparability;the HGB,HCT and PLT detection results by Sysmex XT-1800i,Sysmex XT-2000i and Sysmex XT-4000i have the comparability;the WBC detection results by Sysmex XT-1800i,Sysmex XT-2000i and Mindray BC-5800 have the comparability.
