- Abstract
Background: Automated analyzers are an important component of modern laboratories. As a representative of the newest generation of coagulation analyzers, the CS-5100 features several technical refinements including a pre-analytical assessment unit as well as multi-wavelength optical detection units. Therefore, the CS-5100 is supposed to rapidly and accurately perform a broad panel of coagulation tests. In the current study, the CS-5100 was evaluated regarding its precision and practicability in a clinical laboratory setting. Methods: The CS-5100 was evaluated regarding its intra- and inter-assay precision using commercially available control samples. Results of patient samples, including hemolytic, icteric and lipemic specimens, measured on the CS-5100 were compared to reference analyzers, which are used in our accredited laboratory. Results: The coefficients of variation, assessed in the intra- and inter-assay precision analyses were below 5% representatively for most parameters. Results, obtained by the CS-5100 showed predominantly a high comparability to used reference analyzers, with correlation coefficients ranging from 0.857 to 0.990. Only minor ranged systemic or proportional differences were found in Passing-Bablok regression between the CS-5100 and reference analyzers regarding most of the tested parameters. Lipemic samples had a tendency to deteriorate correlation coefficients, but an overall effect of the sample's triglyceride level could be ruled out. In a routine setting, the analyzer reached a sample throughput rate of 160 tests per hour. Conclusions: The CS-5100 is able to rapidly and precisely measure patient samples. No considerable influence on test comparability was found for elevated levels of free hemoglobin, bilirubin or triglycerides.
