Ferritin Blood Test

Iron Storage Blood Test for Ferritin Level Screening

The Ferritin Blood Test measures the amount of ferritin in your blood. Ferritin is a protein that stores iron and releases it when your body needs it.

This test may help evaluate your body's iron storage level and may be used when checking for possible iron deficiency, iron deficiency anemia, or iron overload.

This service provides access to lab testing only. It is intended as a screening and monitoring tool and does not diagnose, treat, or replace care from a licensed healthcare provider.

✔ Measures stored iron levels
✔ Useful for iron deficiency or iron overload screening
✔ Simple blood draw
✔ Doctor's order included
✔ No insurance required

⏱ Typical turnaround: results are usually emailed in 1–3 days.

What This Test Measures

Serum Ferritin

Ferritin reflects the amount of iron stored in the body. Low ferritin may suggest low iron stores, while high ferritin may be seen with iron overload, inflammation, liver conditions, infection, or other health concerns.

• Test name: Ferritin
• Also known as: Serum Ferritin
• Sample type: Blood
• Purpose: Iron storage screening
• Fasting: May be recommended if instructed

Why Order a Ferritin Test?

• Iron deficiency screening - Ferritin may help identify low iron stores before anemia becomes more severe.
• Anemia evaluation - Ferritin is often reviewed with CBC, hemoglobin, hematocrit, iron, TIBC, or transferrin saturation.
• Iron overload screening - High ferritin may be reviewed when excess iron storage is a concern.
• Fatigue or weakness evaluation - Ferritin may be checked when symptoms could be related to iron status.
• Supplement monitoring - May help monitor iron supplementation with a healthcare provider.
• Provider-directed testing - Useful when your healthcare provider specifically requests ferritin testing.

Who May Consider This Test?

• Individuals with possible low iron or iron deficiency concerns
• People with fatigue, weakness, dizziness, headaches, or pale skin
• Women with heavy menstrual bleeding
• People monitoring iron supplementation
• Individuals with possible iron overload concerns
• Anyone whose healthcare provider requested a ferritin blood test

Important: Ferritin Is Not the Same as Serum Iron

Ferritin measures stored iron. Serum iron measures iron circulating in the blood at the time of testing.

For a more complete iron evaluation, your healthcare provider may also recommend iron, TIBC, transferrin saturation, CBC, hemoglobin, or hematocrit testing.

Important Limitations

• This test does not diagnose anemia, iron deficiency, or iron overload by itself.
• Ferritin can rise with inflammation, infection, liver disease, chronic illness, autoimmune conditions, and some other medical conditions.
• A normal or high ferritin result does not always rule out iron deficiency if inflammation is present.
• Results should be interpreted with symptoms, medical history, and other iron or blood count tests.
• Do not start, stop, or change iron supplements unless directed by your healthcare provider.

Before Ordering

• Follow any fasting instructions included with your lab order.
• Tell your healthcare provider if you take iron supplements, multivitamins, or recently had an iron infusion or blood transfusion.
• If your provider requested a full iron panel, confirm whether iron and TIBC should also be ordered.
• If you are unsure which iron test you need, ask your healthcare provider before ordering.

Frequently Asked Questions

What does a ferritin blood test check?

A ferritin blood test checks the level of ferritin, a protein that stores iron in the body.

Does low ferritin mean low iron?

Low ferritin often suggests low iron stores, but your healthcare provider should interpret results with other labs and your symptoms.

Can ferritin be high for reasons other than iron overload?

Yes. Ferritin may be elevated with inflammation, infection, liver disease, chronic illness, autoimmune conditions, and other health concerns.

Do I need to fast?

You may be instructed to fast before testing. Follow the instructions included with your lab order.

Does this test diagnose anemia?

No. Ferritin provides information about iron storage. Anemia evaluation often also includes CBC, hemoglobin, hematocrit, iron, TIBC, or related tests.

Is a doctor's order included?

Yes. A doctor's order is included with this lab test.
