[Use of the LARC system in a laboratory specializing in hematology (author's transl)]

Two thousand consecutive white blood cell counts were simultaneously studied by the LARC system and the traditional manual method. This comparison enables the following four couclusions to be drawn.--The reproducibility of the LARC differential is superior to the traditional method;--The similarity between results obtained by the LARC and the manual method are good, as indicated by scatter-plots and calculated correlation coefficients;--The LARC system can be substituted for the traditional manual method, also for markedly pathologic samples, but in this case at the price of a slowing down of the through-put rate of the system;--The detection of abnormal white cell types is as good or better with the LARC system as compared with the manual method.
