Test Description: RBC Count (Red Blood Cell Count)

The RBC Count test measures the number of red blood cells (RBCs) in a given volume of blood. Red blood cells are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide to be exhaled. This test is a part of a complete blood count (CBC) and helps assess overall health. Abnormal RBC counts can indicate conditions such as anemia (low RBC count), polycythemia (high RBC count), dehydration, or bone marrow disorders. The RBC count is used to diagnose and monitor various blood-related conditions and is often used as a basic health screening tool.
