Evaluation of the SF-3000 haematology analyser

摘要

This paper describes an evaluation of newly developed SF-3000 haematology analyser. This instrument is smaller than comparable instruments, and uses a semiconductor laser. Its precision and reproducibility were found to be good. Accurate measurements of the leukocyte differential were obtained from stored blood (kept at room temperature and 4℃) for up to 24 hours after collection. A good correlation was found between the SF-3000 and SE-9000 haematology analyser for the red cell and platelet parameters on the 246 samples tested. The leukocyte differential produced by the SF-3000 correlated well with the authors' routine method, with r~2 values over 0.9 for the percentages of neutrophils, lymphocytes and eosinophils.
