Red Blood Cells (RBC)

 Red blood cells or erythrocytes transport oxygen from the lungs to the bodily tissues. RBCs are produced in the red bone marrow, can survive in the peripheral blood for 120 days, and are removed from the blood through the bone marrow, liver, and spleen.

Normal values for red blood cell count:

  • Male adult: 4.5 – 6.2 million/mm3
  • Female adult: 4.5 – 5.0 million/mm3

Indications of RBC count:

  • Helps in diagnosing anemia and blood dyscrasia.
