Measurement accuracy and high throughput are both expected and required in fully automated blood coagulation analyzers. We performed basic examinations of the CS-5100 automated blood coagulation analyzer (CS-5100; Sysmex Corporation, Kobe, Japan). Within-run reproducibility and between-run reproducibility were good, and analysis interference from Hemolysis, Icterus and Lipemia was not observed. PT activity values were slightly lower with ThromboelⓇ S, and D-dimer values were relatively higher with LIAS AUTO D-Dimer NEO in the CS-5100 compared to the blood coagulation analyzer CoaprestaⓇ 2000 (CP2000; SEKISUI MEDICAL Co., Ltd., Tokyo, Japan). We determined these differences were due to differences in reagent formulation. Turnaround time (TAT), the time required from analysis to report, was shortened in the CS-5100, from 31 minutes to 17 minutes compared to the CP2000. In conclusion, the CS-5100 is excellent in making prompt and precise reporting and useful in daily use for analyzing large number of specimens.
