What is a normal RBC lab value?

The normal range for red blood cell (RBC) count typically falls between 4 to 6 million cells per cubic millimeter (mm³) of blood for healthy adults. This range can vary slightly based on several factors such as age, sex, and individual lab standards, but generally, a count within this range indicates adequate production and maintenance of RBCs for essential oxygen transport throughout the body.

A count below this range could suggest anemia or other hematological issues, while significantly higher counts might indicate polycythemia or other conditions. Thus, the chosen range accurately reflects the expected normal values for RBCs in the bloodstream.
