Question

A manual WBC was performed. A total of 36 cells were counted in all 9 mm(2) of a neunbauer-ruled hemocytometer, A 1:10 dilution was used. What was the WBC Count?

Answer 1

The WBC count can be determined by dividing the number of cells counted in the hemocytometer by the dilution factor.

Step-by-step explanation:

The WBC count can be determined by dividing the number of cells counted in the hemocytometer by the dilution factor.

In this case, 36 cells were counted in a 1:10 dilution prepared on a neubauer-ruled hemocytometer. Since the hemocytometer has a counting area of 9 mm^2, we can calculate the WBC count as follows:

WBC Count = (Number of cells counted / Dilution factor) x Area factor

WBC Count = (36 / 10) x (1 / 9) mm^2

WBC Count = 4 x (1 / 9) mm^2

WBC Count = 4/9 mm^2

Therefore, the WBC count is 4/9 cells per mm^2.
