Method Comparison Study - Capillary Samples Direct from Finger
Results from a method comparison study performed on the HemoCue WBC DIFF system and the Sysmex XS-1000i are shown for total
WBC count in Figure 1, for neutrophil count in Figure 2 and for lymphocytes in Figure 3. Capillary sample for Sysmex was taken in a
microtube.
