Consistency is important in science. In using a hemacytometer it is important use a consistent counting methods. Different laboratories might use different patterns of counting but you will utilize the method figured below today. You will count all of cells within each of the four large quadrants in the four corners of each counting chamber on the hemacytometer (see Figure 2). Count all of the cells within each quadrant except those on the far right edge and lower bottom edge (see Figure 5 below). If the number of cells is high, you should use a tally counter to keep track of your counts. View the hemacytometer at the highest magnification that allows you to see an entire quadrant and then focus to visualize the cells
