RBC count (erythrocytes) Study Review
Description
RBCs function in hemoglobin transport, which results in delivery of oxygen to the body tissues.
RBCs are formed by red bone marrow, have a life span of 120 days, and are removed from the blood via the liver, spleen, and bone marrow.
The RBC count aids in diagnosing anemias and blood dyscrasias.
The RBC count evaluates the ability of the body to produce RBCs in sufficient numbers.
RBC Normal Values
Female adult: 4 to 5.5 million cells/μL
Male adult: 4.5 to 6.2 million cells/μL
Nursing consideration: Fasting is not required.

Description
Hemoglobin is the main component of erythrocytes and serves as the vehicle for transporting oxygen and carbon dioxide.
Hemoglobin determinations are important in identifying anemia.
Hematocrit represents red blood cell (RBC) mass and is an important measurement in the identification of anemia or polycythemia
