Complete Blood Counts

Hematocrit: percent of whole blood that is composed of red blood cells (measure of both the number of red blood cells and the size of red blood cells)

Hemoglobin: total amount of hemoglobin in a volume of blood (measure of oxygen carrying capacity of blood)

* Hemoglobin and hematocrit offer equivalent information and are interchangeable


Red Blood Cell Distribution Width: meansure of the variability of MCV distributions

Mean Cell Volume = HCT/RBC

Mean Cell Hemoglobin Concentration = HGB/HCT

Mean Cell Hemoglobin = HGB/RBC
