  • Children: Between 4-5.5 million red blood cells per microliter of blood.
  • Women: between 4.2-5.4 million red blood cells per microliter of blood.
  • Men: Between 4.7-6.1 million red blood cells per microliter of blood.

  • Excess production of red blood cells in the bone marrow: which may be due to myeloproliferative neoplasm and polycythemia vera.
  • Low oxygen percentage: More red blood cells are produced in the body in response to a decrease in the level of oxygen in the blood, such as suffering from sleep apnea, smoking, and heart and lung diseases.
  • Kidney disease: Some kidney diseases, or kidney cancer in some rare cases, may lead to an overproduction of the hormone erythropoietin. Which stimulates the production of more red blood cells.
