reported as the number of WBCs/μL or in SI units as WBCs/L.
Example 13-3
In squares 1–9 of a hemacytometer, the following numbers of WBCs were counted:
Side 1 Side 2
Square Cells Counted Square Cells Counted
1 6 1 7
2 5 2 7
3 7 3 6
4 8 4 5
5 9 5 6
6 6 6 8
7 7 7 7
8 5 8 8
9 6 9 7
Total 59 61
Find the average number of WBCs.
59 61 60 average (number of sides)

Since 9 squares were counted, multiply the total count for all nine squares by 0.1 (10%) and add this
number to the total for the nine squares. Multiply this sum by 100, the dilution factor.
WBCs/μL 60 0.1 (60) 66 100 6,600
