Final answer:
Mean Corpuscular Volume (MCV) is the indicator used to measure the average size of Red Blood Cells in order to assess their health and diagnose conditions such as anemia.
Step-by-step explanation:
The indicator used to measure the average size of Red Blood Cells (RBCs) is the Mean Corpuscular Volume (MCV). The MCV is part of a standard complete blood count test and provides important diagnostic information. It classifies RBCs according to their size: normal-sized cells are referred to as normocytic, smaller-than-normal are microcytic, and larger-than-normal cells are macrocytic.
This information helps in diagnosing different types of anemia and understanding the health of the erythrocytes.Mean Corpuscular Volume (MCV) is the indicator used to measure the average size of Red Blood Cells in order to assess their health and diagnose conditions such as anemia.
