What is the normal range for RBC count?

The normal range for red blood cell (RBC) count for adults is typically between 4 million and 6 million cells per microliter of blood. This range can vary slightly based on factors like age, sex, and the laboratory's reference values, but generally, 4-6 million is accepted as the standard range for healthy individuals.

RBCs are essential for transporting oxygen throughout the body, and maintaining an appropriate count is crucial for overall health. A count below or above this normal range could indicate anemia or other health issues, such as polycythemia, which can have significant clinical implications. Understanding normal lab values is vital for assessing a patient's overall health and can guide further diagnostic and therapeutic interventions.

Other options fall outside the typical values for RBC counts and would not reflect normal physiological conditions for adult patients.
