EVALUATION OF THE SF-3000 HEMATOLOGY ANALYZER

This paper describes an evaluation of newly developed SF-3000 haematol ogy 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 degre es C) for up to 24 hours after collection. A good correlation was foun d between the SF-3000 and SE-9000 haematology analyser for the red cel l and platelet parameters on the 246 samples tested. The leukocyte dif ferential produced by the SF-3000 correlated well with the authors' ro utine method, with r(2) values over 0.9 for the percentages of neutrop hils, lymphocytes and eosinophils.
