title: A comparison of differential white blood cell counts using manual technic and the Coulter S-Plus IV.
abstract: The results of 100-cell and 500-cell manual differential white blood cell counts were compared with those obtained using a Coulter S-Plus IV electronic particle counter. Significant (P less than 0.001) correlations were observed between the manual and instrument-derived data for percentages of granulocytes and lymphocytes.
