Ferritin: Normal Values and What a Low Ferritin Means

Ferritin is the most sensitive early indicator of iron status. Regular testing helps detect depletion before symptoms appear, supporting proactive health management.

Choose male or female — this range differs by sex.

Enter your age — this range changes with age.

This range also depends on context such as cycle phase or sample material; the highlighted rows apply to your group.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test measures the amount of ferritin in your blood. Low ferritin indicates depleted iron stores, while high ferritin may suggest iron overload or inflammation.

Why It Matters

Iron is essential for oxygen transport, energy production, and immune function. Ferritin testing helps detect iron deficiency before anaemia develops, or iron overload which can damage organs. Consult your healthcare provider for personalised advice.

When to Test

Testing may be recommended if you experience fatigue, weakness, pale skin, dizziness, or shortness of breath. Women with heavy menstrual periods and active individuals may benefit from regular ferritin monitoring.

Symptoms

Low Levels

Symptoms of low ferritin may include fatigue, weakness, pale skin, brittle nails, hair loss, headaches, and difficulty concentrating. Low ferritin can precede iron-deficiency anaemia.

High Levels

High ferritin may be associated with joint pain, abdominal pain, fatigue, and skin discolouration. Elevated levels can indicate iron overload, liver disease, or chronic inflammation.

Recommendations

Male

If Low

Low ferritin indicates depleted iron stores. Consider iron supplementation and dietary iron increase (red meat, spinach).

If High

High ferritin may indicate inflammation, hemochromatosis, or liver disease. Consider CRP testing and comprehensive metabolic evaluation.

Female

If Low

Low ferritin indicates depleted iron stores. Consider iron supplementation and dietary iron increase (red meat, spinach, fortified cereals).

If High

High ferritin may indicate inflammation, hemochromatosis, or liver disease. Consider CRP testing and comprehensive metabolic evaluation.

Lifestyle Tips

Include iron-rich foods such as lean red meat, poultry, fish, beans, and fortified cereals. Pair iron-rich foods with vitamin C sources to enhance absorption. Avoid drinking tea or coffee with meals, as they can reduce iron absorption.

Frequently Asked Questions

What is the difference between ferritin and iron?
Iron is the mineral itself, while ferritin is the storage protein for iron. Ferritin reflects your body's long-term iron reserves, making it a better indicator of overall iron status.
Can ferritin be high without iron overload?
Yes, ferritin can be elevated due to inflammation, infection, or liver disease, even without true iron overload. Your healthcare provider may order additional tests to clarify the cause.
How can I increase my ferritin levels naturally?
Eating iron-rich foods, pairing them with vitamin C, and avoiding inhibitors like tea and coffee with meals may help. Consult your healthcare provider before starting iron supplements.
