A new generation, fully automated coagulation analyzer with a walk-away reagent management concept

The cobas t 711 coagulation analyzer utilizes a walk-away reagent management (W.A.R.M.) concept and has demonstrated accurate and reproducible sample measurement in routine practice. Extended routine testing was faster on the cobas t 711 coagulation analyzer than on three comparator systems. Total and weekly hands-on time was negligible on the cobas t 711 coagulation analyzer. Factors associated with the W.A.R.M. concept, including high test capacity, good onboard stability, reduced reagent top-ups, automated reconstitution and scheduling of reconstitution, and automated overnight maintenance, reduced the laboratory workload and increased efficiency. All outcomes relating to quality control were slower with the cobas t 711 coagulation analyzer versus comparator analyzers. However, automated maintenance processes that require no hands-on time from laboratory staff can happen in the background and can be programmed to take place at night. Overall, these results indicate that the cobas t 711 analyzer could streamline workflow and efficiency in coagulation laboratories.
