What does this test do?
This test determines the concentration of transferrin circulating in the bloodstream. Transferrin is an important protein that is responsible for transporting iron in the bloodstream. When red blood cells die, the iron from their hemoglobin is released and carried by transferrin to the bone marrow, where iron is stored and recycled as needed to make new red blood cells.
What do the results mean?
High levels of transferrin may indicate iron deficiency as a cause of anemia. Abnormally low levels of transferrin may indicate a state of malnutrition.
