Diagnostic Blood Test:
Ferritin is a protein in the blood that helps store iron, which is important in forming hemoglobin (the protein that transports oxygen to the body’s tissues). Having high ferritin levels may be a sign of having too much iron stored in the body, which may point to liver disease, haemochromatosis, or thyroid dysfunction. Ferritin is also an acute-phase reactant and may be elevated due to inflammation. Low ferritin may indicate anemia or bleeding problems.
