A ferritin blood test measures ferritin, a protein that stores iron inside cells. Because ferritin reflects the body's iron reserves, it is one of the most useful tests for detecting iron deficiency before anemia develops, and for identifying iron overload. It is often ordered with other iron studies when a person has fatigue, shortness of breath, or unusual pallor, or when a provider is monitoring a chronic condition. Ferritin is also an acute-phase protein, so inflammation, infection, and liver disease can raise it independently of iron stores.

• Ferritin Measures the protein that stores iron and reflects the body's iron reserves.
• Transferrin saturation May be added with other iron studies to show how much iron is bound to transport proteins.

• People with fatigue, weakness, or shortness of breath
• Individuals being evaluated for iron deficiency or anemia
• People with a chronic condition that affects iron balance
• Those being monitored for possible iron overload

• No fasting is usually required.
• Tell the collector about iron supplements or recent illness.
• Follow any instructions provided for your specific panel.

A low ferritin generally suggests depleted iron stores, even when other blood counts are still normal. A high ferritin can reflect iron overload but may also rise with inflammation, infection, or liver disease, so it is interpreted alongside other findings. Discuss results with a healthcare provider, who can consider your symptoms, history, and additional tests.
