HEMOGLOBIN

The hemoglobin test measures the level of hemoglobin, a protein in red blood cells that carries oxygen, in the blood. This test is used to diagnose and monitor conditions affecting red blood cells, such as anemia, polycythemia, and bleeding disorders. Low hemoglobin levels indicate anemia, which can result from various causes, such as iron deficiency, chronic disease, or bone marrow disorders. Elevated hemoglobin levels suggest polycythemia or other conditions causing increased red blood cell production. The hemoglobin test provides valuable information for assessing overall health, diagnosing underlying conditions, and guiding treatment decisions.
