Part C

1. Differential white blood cell count data table. As you identify white blood cells, record them on the table by using a tally system, such asTH4. I I. Place tally marks in the "Number Observed" column and total each of the five WBCs when the differential count is completed. Obtain a total of all five WBCs counted to determine the percent of each WBC type.
