Hemoglobin test. Overview. A hemoglobin test measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count (anemia).
This is a blood test to find out how much hemoglobin is in your blood. Hemoglobin is the main part of your red blood cells. Hemoglobin is made up of a protein called globin and a compound called heme. Heme consists of iron and a pigment called porphyrin, which gives your blood its red color.Hemoglobin serves the important role of carrying oxygen and carbon dioxide through your blood.nemia can be caused by blood loss, decreased production of red blood cells, or increased destruction of red blood cells. Your healthcare provider can use your hemoglobin test to help find the cause of your anemia. These are other reasons you may need this test: To diagnose a disease that causes anemia.
