Iron plays a crucial role in many of the body’s essential functions, from carrying oxygen to supporting immunity and energy production. However, assessing iron levels isn't just about checking haemoglobin. One of the most accurate ways to evaluate the body’s iron stores is through a serum ferritin test. Ferritin is a protein that stores iron, and measuring its levels in the blood helps identify imbalances that may not show up in basic blood tests. In this article, we’ll explore what serum ferritin is, what the test measures, the normal ranges, symptoms of imbalance, and how to manage ferritin levels, along with how MaxAtHome makes ferritin testing accessible from home.

What is Ferritin and What Does the Serum Ferritin Test Measure?

Ferritin is a protein that stores iron in the body and releases it when needed. Most of the ferritin is found inside cells, but a small amount circulates in the blood. This circulating ferritin level, known as serum ferritin, reflects the body's total iron storage.

The serum ferritin test measures how much iron is stored in the body, not just how much is currently in circulation. It is considered more reliable than a basic iron test when it comes to diagnosing iron deficiency or overload.

Unlike haemoglobin, which can remain within range even in early deficiency, serum ferritin often drops first, making it a valuable tool for early diagnosis.

Who Needs Ferritin Testing and Why?

A serum ferritin test is recommended when there are signs of iron deficiency or excess, or as part of ongoing monitoring for chronic health conditions. Because ferritin levels can change before haemoglobin drops, it’s a useful early indicator of iron imbalance, even in individuals who appear healthy.

Ferritin testing may be advised for:

• Individuals with persistent fatigue, weakness, or dizziness

• People experiencing hair loss, brittle nails, or pale skin

• Women with heavy periods or frequent pregnancies

• Patients with chronic conditions like kidney disease, liver disease, or inflammatory disorders

• Monitoring during iron therapy to track response and avoid overload

• People with symptoms of anaemia or iron overload

A ferritin test is also commonly included in evaluations before or during treatment for unexplained symptoms like brain fog, muscle weakness, or frequent infections.

Ferritin Levels During Pregnancy

During pregnancy, the body’s demand for iron increases significantly to support the growing foetus and the expanding blood volume of the mother. Monitoring serum ferritin levels is essential to prevent complications related to iron deficiency, such as maternal anaemia, fatigue, and low birth weight.

Key points about ferritin in pregnancy:

• Ferritin levels naturally decline as pregnancy progresses, especially in the second and third trimesters.

• Low ferritin may result in fatigue, dizziness, or breathlessness, even with normal haemoglobin.

• Consistently low levels increase the risk of preterm delivery, postpartum anaemia, and poor foetal growth.

• Supplementation is often recommended if ferritin levels fall below recommended ranges.

Regular screening helps ensure timely dietary or medical interventions, especially for women with back-to-back pregnancies or those following vegetarian diets.

Ferritin Normal Range by Age and Gender

Serum ferritin levels can vary depending on age, gender, and physiological conditions such as pregnancy. Understanding what constitutes a normal ferritin level helps in identifying early signs of iron deficiency or overload.

Here is a general guide to normal ferritin levels by age and gender:

Note: Reference values may vary slightly between laboratories. Doctors also consider clinical symptoms and other tests before interpreting ferritin results.

What Does It Mean If Ferritin is Too Low or Too High?

Abnormal serum ferritin levels, whether too low or too high, can be early indicators of various underlying health issues. While low levels usually point to iron deficiency, high ferritin may be a sign of inflammation or iron overload.

Low Serum Ferritin

Low ferritin often appears before haemoglobin drops, making it a crucial early marker of iron deficiency. It may be caused by:

• Poor dietary iron intake

• Heavy menstrual bleeding

• Frequent blood donation

• Malabsorption conditions (e.g., celiac disease)

• Chronic illness or inflammation

• Pregnancy-related iron demands

What is Dangerously Low Ferritin?

A serum ferritin level below 15 ng/mL is generally considered very low and may require iron supplements or treatment.

High Ferritin Levels

Elevated ferritin can indicate:

• Inflammation or infection

• Liver disease or alcohol-related liver damage

• Hemochromatosis (a condition causing iron overload)

• Chronic conditions such as rheumatoid arthritis or cancer

High ferritin levels must be interpreted alongside other blood tests like serum iron, TIBC, and CRP to rule out inflammation versus actual iron overload.

Maintaining Healthy Ferritin Levels

Balanced ferritin levels are essential for overall health, energy, and immune function. Both low and high ferritin can be managed with the right combination of lifestyle, diet, and medical supervision.

Tips to maintain normal ferritin levels:

• Include iron-rich foods in the diet: green leafy vegetables, lentils, legumes, nuts, seeds, red meat, and fortified cereals.

• Pair iron sources with vitamin C (such as citrus fruits or tomatoes) to boost absorption.

• Avoid excessive tea or coffee around mealtimes, as they can hinder iron absorption.

• Follow prescribed supplements carefully, avoid self-medicating with iron, especially if ferritin is already high.

• Treat underlying conditions (such as chronic infections or inflammation) that may affect iron metabolism.

• Engage in regular physical activity to support overall metabolism and blood health.

Maintaining ferritin is not only about diet, it also involves managing chronic conditions and improving overall health through lifestyle changes.

Frequently Asked Questions (FAQs)

What is ferritin and why is it important?

Ferritin is a protein that stores iron in the body. It helps ensure there’s enough iron available for vital functions like oxygen transport, energy production, and immunity.

What is the normal serum ferritin level for females?

The normal ferritin range for adult females is typically 11 to 307 ng/mL, but may vary slightly depending on the lab and age. During pregnancy, levels may drop and require monitoring.

What are the symptoms of dangerously low ferritin levels?

Symptoms include extreme fatigue, breathlessness, hair loss, brittle nails, pale skin, and in severe cases, irregular heartbeat or weakness during physical activity.

Can ferritin levels be low even if haemoglobin is normal?

Yes. Ferritin is often the first to drop in iron deficiency, even before haemoglobin is affected. That’s why it’s useful for early detection.

What causes high ferritin levels in the blood?

High ferritin may be due to infections, inflammation, liver disease, iron overload (hemochromatosis), or excessive iron supplements. It’s important to evaluate alongside other tests.

Is fasting required for a ferritin test?

No, fasting is not usually required. However, it’s best to follow the lab or doctor’s instructions before the test.
