Hemoglobin Levels Topic Guide

Hemoglobin Hemoglobin: Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues, and returns carbon monoxide from the tissues back to the lungs. Hemoglobin values are related to a person's age and sex. Low hemoglobin levels in the blood are referred to as anemia. High hemoglobin levels in the blood are caused by
  • cancer,
  • lung diseases,
  • bone marrow disorders,
  • blood doping,
  • living at a high altitude, and
  • inappropriate use of the drug Epogen.
Treatment of a high or low hemoglobin level depends on the cause.
