You are counting white blood cells in a freshly drawn blood sample. You dilute the blood 1/20 in 5% acetic acid to lyse the red blood cells and then do a 1/2 dilution in trypan blue before loading the cells into a hemocytometer. You count 87 cells in the four large corner squares in the hemocytometer. What is the number of white blood cells / ml in the blood sample? O 2.17 x 10 O 870 O 8.7 x 10 O 8.7 x 10
