Evaluation of capacity for sample processing of the automated coagulation analyzer STACIA CN10

Abstract

Coagulation tests using an automated analyzer are popular, but sample processing capacity could decrease when multiple items with different measurement principles are simultaneously measured. Recently, the automated coagulation analyzer “STACIA CN10” has been developed. STACIA CN10 shows improved sample processing capacity through the use of a measuring table independent of each measurement principle. Therefore, we evaluated the sample processing capacity of STACIA CN10. The total assay time for 50 samples was 62 min 58 s with STACIA CN10, which was about 20 min shorter than that (82 min 59 s) with CS-5100. On the other hand, the assay time of each sample was about 3 min 30 s longer on average than that with CS-5100. Therefore, we investigated the sampling interval of both analyzers, and the results showed that the sampling interval of STACIA CN10 was about 30 s shorter on average than that of CS-5100. From these results, it is considered that STACIA CN10 shortened the sampling interval independent of the measuring table and improved the sample processing capacity in the case of continuous measurements of multiple items. STACIA CN10 has better sample processing capacity than CS-5100 and is considered to be useful for routine examinations.
