Cell count validation results. (a) Representation of linearity for serial dilution counts by hemocytometer, automated total, and viable cell count. In the table, the linearity () and accuracy error () values (considering the hemocytometer count as the expected one) were reported. (b) Intra-assay and interassay precision expressed as CV for all the three counting methods.
