Use: A red blood cell count measures the number of red blood cells, and is used to diagnose anemia and other conditions affecting red blood cells. The red blood cell count is also useful in individuals with symptoms of problems with red blood cell production, including fatigue and paleness.
Limitations: Cold agglutinins and rare warm agglutinins causes decreased RBC counts. Increased white cell counts may cause falsely elevated RBC counts.
Additional Information: A recent blood transfusion can affect red blood cell counts, as can pregnancy. Individuals who live at higher elevations may have higher red blood cell counts, and women have lower red blood cell counts than men.
