  C. 9:1

• Question 572:

  First, determine the number of WBC's from the hemocytometer as follows:

  WBC count = (dilution ratio x # of cells counted x 10) / (# mm2 area counted) Then: WBC count = (20 x 100 x 10) / (8) = 2500 WBC/mm3 (or 2500 WBC/uL or 2.5 x 103 WBC/uL)

  Next, to find the WBC count per liter, multiply the WBC count/uL by the number of uL/L (there are 106 uL/L)

  So: (2.5 x 103 WBC/uL) x (106 uL/L) = 2.5 x 109 WBC/L

  Hematology

  A 1:20 dilution is made for a manual WBC count. The four corner squares on both sides of a hemocytometer are counted. A TOTAL of 100 cells are counted in that area. What is the white blood cell count in terms of a liter (? x 10^9/L)?

  A. 2.5
