Introduction
If you’ve been feeling unusually tired, weak, or dizzy, your doctor might recommend a ferritin test. But what exactly is this test, and why is it important? Let’s break it down in simple terms so you can understand what to expect and why it matters for your health.
What is a Ferritin Test?
A ferritin test measures the level of ferritin in your blood. Ferritin is a protein that stores iron in your body. Iron is essential for making red blood cells, which carry oxygen to your organs and tissues. If your ferritin levels are too low or too high, it could indicate an underlying health issue.

Why is This Test Done?
Your doctor may order a ferritin test if they suspect:
• Iron deficiency anaemia (low iron levels causing fatigue, weakness, or pale skin).
• Iron overload (too much iron, which can damage organs).
• Chronic diseases (such as liver disease or inflammation).
Symptoms That May Require a Ferritin Test
Low Ferritin (Iron Deficiency) Symptoms:
• Extreme tiredness or weakness
• Pale skin
• Shortness of breath
• Dizziness or lightheadedness
• Brittle nails or hair loss
• Unusual cravings for non-food items (like ice or dirt)
High Ferritin (Iron Overload) Symptoms:
• Joint pain
• Stomach pain
• Fatigue
• Unexplained weight loss
• Heart problems (in severe cases)
If you experience any of these symptoms, consult your doctor—they may suggest a ferritin test to check your iron levels.
How is the Ferritin Test Done?
The ferritin test is a simple blood test. Here’s what you can expect:
1. Preparation:
• Usually, no fasting is required, but follow your doctor’s instructions.
• Inform your doctor about any medications or supplements you take, as some can affect results.
2. Blood Sample Collection:
• A healthcare professional will clean your arm and insert a small needle to draw blood.
• The process takes just a few minutes and may cause slight discomfort.
3. After the Test:
• You can resume normal activities immediately.
• Results are typically available within a day or two.
Understanding Your Results
Ferritin levels are measured in nanograms per millilitre (ng/mL). Normal ranges vary slightly by lab, but generally:
• Men: 24–336 ng/mL
• Women: 11–307 ng/mL
What Low Ferritin Means:
It means:
• Indicates iron deficiency, which can lead to anaemia.
• Common causes: poor diet, blood loss (heavy periods, ulcers), or pregnancy.
What High Ferritin Means:
• It could signal iron overload (hemochromatosis), inflammation, or liver disease.
• It may also occur due to excessive iron supplements or chronic illnesses.
Your doctor will explain your results and recommend the next steps if needed.
How to Improve Ferritin Levels Naturally
For Low Ferritin (Iron Deficiency):
• Eat iron-rich foods: Spinach, red meat, lentils, beans, and fortified cereals.
• Pair with vitamin C: Helps iron absorption (e.g., oranges with iron-rich meals).
• Avoid calcium/tea with meals: These can block iron absorption.
• Consider supplements (if prescribed).
For High Ferritin (Iron Overload):
• Avoid excess iron supplements.
• Limit red meat and iron-fortified foods.
• Donate blood (if recommended by a doctor).
• Treat underlying conditions (e.g., liver disease).
When to See a Doctor
If your test results are abnormal, your doctor may suggest:
• Further tests (like a full iron panel or genetic testing for hemochromatosis).
• Dietary changes or supplements.
• Treatment for underlying conditions.
Final Thoughts
A ferritin test is a simple yet powerful way to check your iron levels. Whether you’re dealing with fatigue, weakness, or other unexplained symptoms, this test can provide valuable insights into your health. By understanding your results and making necessary lifestyle changes, you can improve your well-being and feel your best.
