Ferritin Test Popular

The Ferritin Test measures the level of ferritin in your blood, which reflects how much iron your body has stored. Ferritin is a protein found in nearly all cells and serves as the primary storage form of iron. Most iron stores are located in the liver, spleen, and bone marrow.

Because ferritin levels closely reflect total body iron, this test is considered the most reliable single blood test for identifying iron deficiency, often detecting low iron stores before anemia develops.

Ferritin testing is also used to help identify iron overload conditions, monitor iron-related treatment, and distinguish iron-deficiency anemia from other types of anemia. Since ferritin can increase during inflammation or infection, results are best interpreted alongside symptoms and other lab tests.

What Is Included In This Test?

This test measures serum ferritin, which indicates the amount of iron stored in your body.

What Ferritin Levels Can Tell You

• Low ferritin levels suggest depleted iron stores and are a strong indicator of iron deficiency or iron-deficiency anemia. Low levels may cause symptoms such as fatigue, weakness, dizziness, headaches, and shortness of breath.
• High ferritin levels may indicate iron overload or be associated with inflammation, liver disease, infection, or certain blood disorders. Excess iron can damage organs over time, particularly the liver.

When combined with other iron studies—such as serum iron, transferrin, and iron saturation—ferritin helps differentiate between common types of anemia, including:

• Iron deficiency anemia
• Anemia of chronic disease
• Thalassemia

Ferritin testing is also used to monitor response to iron therapy or treatment for iron overload.

Who Should Consider This Test?

The Ferritin Test is helpful for adults who want to better understand their iron status or are experiencing symptoms related to abnormal iron levels.

You should consider this test if you:

• Have fatigue, weakness, dizziness, or shortness of breath
• Have been told you may have anemia or low iron
• Have heavy menstrual periods or a history of blood loss
• Follow a vegetarian or low-iron diet
• Have conditions affecting iron absorption, such as celiac disease or gastric bypass surgery
• Are pregnant or planning pregnancy
• Have a family history of iron overload or hemochromatosis
• Are receiving iron supplements or treatment and need ongoing monitoring
• Have liver disease, chronic inflammation, or frequent infections

This test does not diagnose a specific condition on its own but provides essential insight that helps guide further evaluation and treatment decisions.

If you’re experiencing symptoms of low or high iron, a ferritin test is a simple and effective way to get clear answers.
