Exercise 46

Assume that you are performing an RBC count in the POL where you work using the Unopette kit for RBC. You count the red blood cells under high-power magnification and come up with these tallies for the five squares on one side of the hemacytometer counting chamber: 100, 99, 103, 94, and 105. For the other side of the counting chamber the numbers are 103, 105, 98, 97, and 101. Calculate the patient’s RBC count, showing all of the steps.
