Hemoglobin is needed in the body to carry oxygen through out the body. It is the protein portion of the blood.

What a Hemoglobin Test Detects
Hemoglobin testing can reveal numerous aspects of the blood. Anemia can occur if the body’s hemoglobin levels are too low. This can cause many health complications for a person. When the hemoglobin levels in the blood are elevated, polycythemia vera can occur. This is a health condition that causes the marrow of bone to produce too much of the body’s red blood cells. Many environmental factors and poor health decisions can cause hemoglobin levels to rise.
