The gating dot plot below identifies a predominant CD45 bright FS small used cells.
The advantages of flow cytometry are based largely on its ability to analyse rapidly and simultaneously multiple cell properties in a quantitative manner. The official flow cytometry labo- ratory report is most commonly an individual-lab-generated paper report form. This is especially true if initial testing showed an increased number of lymphocytes abnormal cell counts or the presence of immature blood cells.
