[Use of the LARC system in a laboratory specializing in hematology (author's transl)]. 1978

G Flandrin, and P Bouffette, and M T Daniel, and F Valensi

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.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D009504	Neutrophils	Granular leukocytes having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral dyes.
