Calculate the WBC count in the following from the information provided:
-Using a 1:10 dilution,64 cells are counted in five large squares on both sides of the hemocytometer.

Question

Quizplus · Accepted Answer

Since a 1:10 dilution was used, the WBC count needs to be multiplied by 10 to obtain the total count.

Number of cells counted = 64 
Number of squares counted = 10 (5 squares on both sides)

Therefore, the total count = 64 x 10 x 10^4 (dilution factor)

= 6400 cells/µL

However, the question is asking for the WBC count, so we need to multiply the total count by the dilution factor of the hemocytometer, which is 1/10.

WBC count = 6400 x 1/10

= 640 cells/µL.

Therefore, the correct answer is C.
