What is Hemoglobin?
Hemoglobin (Hgb) is the protein within red blood cells that binds to and carries oxygen. Measuring hemoglobin concentration is a primary test for anemia (low Hgb) or polycythemia/erythrocytosis (high Hgb). Anemia leads to fatigue and reduced exercise capacity due to impaired oxygen delivery.
