Ferritin Test: Normal Range & Signs of Low Ferritin

A ferritin test is a blood test that measures the amount of stored iron in your body. Normal ferritin levels typically range from 15-200 ng/mL in women and 30-500 ng/mL in men. Levels below this range often indicate low ferritin, a common cause of fatigue, pale skin, hair loss, and shortness of breath, and can progress to iron deficiency anemia if left untreated.

If you've been feeling unusually tired, dizzy, or short of breath, your doctor may order a ferritin test alongside a full iron profile test to check whether low iron stores are the cause. This guide breaks down what the test measures, how to read your results, normal ferritin ranges by age and gender, the warning signs of low ferritin, what high ferritin means, and how much a ferritin test typically costs.

What Is a Ferritin Test?

A ferritin test, also called a serum ferritin test, measures the amount of ferritin - a protein that binds and stores iron inside your cells - circulating in your blood. Because ferritin levels rise and fall in proportion to your body's total iron reserves, doctors use this test as an early marker of iron deficiency or iron overload, often before other symptoms of anemia appear on a standard complete blood count (CBC).

Unlike a simple iron test, which only measures the iron currently circulating in your bloodstream, ferritin reflects your body's long-term iron "savings account." This is why a ferritin blood test is usually ordered together with an iron profile test that also includes:

• Serum iron

• Total iron-binding capacity (TIBC)

• Transferrin saturation (%)

• Complete blood count (CBC) / hemoglobin

Doctors commonly order this panel to investigate unexplained fatigue, restless legs, hair thinning, heavy menstrual bleeding, suspected hemochromatosis (iron overload), or to monitor chronic conditions such as kidney disease, liver disease, and certain inflammatory disorders.

How Does a Ferritin Test Work?

A ferritin test works like any standard blood draw and takes only a few minutes:

• A phlebotomist draws a small blood sample from a vein in your arm.

• The sample is sent to a lab, where it's analyzed using an immunoassay technique that detects ferritin protein levels.

• Results are typically available within 24-48 hours, and reported in nanograms per millilitre (ng/mL), also written as µg/L.

Most labs don't require fasting for a ferritin test, though your doctor may ask you to fast for 8-12 hours if it's being run alongside a full lipid or glucose panel. It's best to avoid iron supplements for 24 hours before the test and to mention any recent infection, since ferritin can temporarily rise during inflammation, skewing results.

Ferritin Test Normal Range

Ferritin blood level reference ranges vary between laboratories, but the commonly accepted normal ranges are:

Signs of Low Ferritin

What Does Low Ferritin Mean?

Low ferritin means your body's iron stores are running low, even if your hemoglobin still looks normal on a basic blood test. Left untreated, low ferritin frequently progresses to iron deficiency anemia. Common causes include heavy menstrual periods, pregnancy, poor dietary iron intake, frequent blood donation, gastrointestinal blood loss, and malabsorption conditions like celiac disease.

Common Signs & Symptoms of Low Ferritin

• Persistent fatigue or low energy, even after adequate sleep

• Pale skin or pale inner eyelids

• Shortness of breath during light activity

• Frequent headaches or dizziness

• Brittle nails and unusual hair shedding

• Restless legs syndrome, especially at night

• Cold hands and feet

• Difficulty concentrating ("brain fog")

• Unusual cravings for ice, chalk, or dirt (a condition called pica)

• Rapid or irregular heartbeat

If you're experiencing several of these symptoms, a low ferritin blood level is worth ruling out - especially for women of reproductive age, endurance athletes, vegetarians/vegans, and frequent blood donors, who are at the highest risk.

What Does High Ferritin Mean?

High ferritin can mean two very different things, so context matters. It may signal genuine iron overload (hemochromatosis), where excess iron builds up in the liver, heart, and joints. Or, more commonly, it can simply reflect inflammation, since ferritin behaves as an "acute phase reactant" that rises temporarily during infections, liver disease, obesity, heavy alcohol use, or certain cancers.

Signs sometimes associated with high ferritin include joint pain, fatigue, abdominal pain, and in advanced iron overload, skin bronzing or discoloration. Because elevated ferritin has so many possible causes, doctors usually pair it with transferrin saturation and liver function tests to pinpoint the real reason before starting treatment.

Ferritin Test vs Iron Profile Test: What's the Difference?

People often search for an "iron test" or "iron profile test" when they actually mean a ferritin test - but they're not identical:

• Serum iron test: Measures iron currently circulating in the blood at that exact moment; fluctuates throughout the day.

• Ferritin test: Measures stored iron reserves; far more stable and a better long-term indicator.

• Iron profile test: A full panel that includes serum iron, TIBC, transferrin saturation, and often ferritin together for a complete picture.

For most people investigating fatigue or suspected anemia, doctors recommend the complete iron profile test rather than ferritin alone, since it distinguishes true iron deficiency from inflammation-driven changes.

For added convenience, home sample collection is available across serviceable locations. You can book your Ferritin Test online or visit your nearest Simira Diagnostics center.

How to Improve Low Ferritin Naturally

Mild to moderate low ferritin can often be improved through diet and lifestyle changes, though moderate-to-severe deficiency usually needs supplements prescribed by a doctor:

• Eat iron-rich foods: red meat, poultry, fish, lentils, spinach, and fortified cereals

• Pair plant-based iron (non-heme iron) with vitamin C-rich foods like citrus or bell peppers to boost absorption

• Limit tea and coffee around mealtimes, as tannins reduce iron absorption

• Address the underlying cause - heavy periods, GI bleeding, or malabsorption - rather than iron alone

• Recheck ferritin levels 8-12 weeks after starting treatment to track progress

Conclusion

A ferritin test is one of the simplest, most informative blood tests for catching iron deficiency early - often before symptoms of anemia show up on a standard blood count. Knowing your normal ferritin range, recognizing the signs of low ferritin, and understanding what high ferritin means can help you and your doctor act early. If you're experiencing fatigue, hair loss, or unexplained weakness, book a ferritin blood test or a complete iron profile test to get clarity on your iron health.
