In a CBC for red blood cells, your providers look at: 1. Red blood count (RBC).This is the number of red blood cells in a certain amount of blood, usually a microliter (mcL).

The results of your platelet count on a CBC include: 1. Platelet count.The total number of platelets in your blood sample. 2. Mean platelet volume (MPV).MPV is your average platelet size.
