When Mindray BC2800 blood ball meter counts, the white blood cell count is normal, and red blood cells and platelets are not counted. Why?

Check the counting mode and see if it is WBC/HGB mode. It should be whole blood full parameter mode or pre-dilution full parameter mode. Instrument failure is the result that only white blood cells and hemoglobin are displayed on the screen, and nothing is displayed in the column of red blood cells. In addition, the WBC system in which the sample only shows the results is reviewed, and RBC has no information.
