Sigma Metric Analysis
A poster from the 2005 AACC convention provides us with a great set of data on CV and bias for a new chemistry instrument. From that data, we can evaluate the Sigma performance and the QC required by the instrument. We can even compare the new instrument with Sigma metrics from other competing instruments.
We highlight a poster from the 2005 AACC/ASCLS/IFCC conference, "Evaluation of the Beckman Coulter UniCel DxC 800 Synchron Clinical System", (H. Stiegler, A. Breuer, A. Pozun, M. Krieg). The data provided in this evaluation can be converted into Sigma metrics.
We analyze some data from the field and look at performance in the Roche Modular instrument.
An analysis of the Sysmex SE-9500
This is a rare opportunity: to analyze multiple performance studies on a single instrument. By looking back through two scientific journals, we were able to find studies around the world that describe the performance of the Sysmex XT 2000i.
