Ferritin Normal Range By Age

Ferritin ranges vary by lab and sex. Common adult ranges are about 30-300 ng/mL for men and 15-200 ng/mL for women.

Ferritin ranges are easy to search for and hard to interpret cleanly. Your age, sex, lab method, inflammation status, and the reference interval printed on the report all matter. A useful starting point is this: common adult ferritin ranges are about 30-300 ng/mL for men and about 15-200 ng/mL for women, but your own lab range comes first.

Overview

Ferritin is the main blood marker used to estimate stored iron. Low ferritin usually means iron stores are depleted. High ferritin can mean increased iron stores, but it can also rise because ferritin is an acute phase reactant during inflammation, infection, liver disease, tissue injury, alcohol use, obesity, autoimmune disease, malignancy, or hyperthyroidism.

That dual role is why a ferritin range chart is only a starting point. The same number can mean different things depending on whether hemoglobin is normal, TSAT is low or high, CRP is elevated, or liver tests are abnormal.

What This Result Usually Means

If ferritin is within your lab range, it often suggests iron stores are not clearly depleted or excessive. If ferritin is below range, iron deficiency becomes more likely. Ferritin below 30 ng/mL generally supports iron deficiency, including iron deficiency without anemia when hemoglobin is still normal.

If ferritin is above range, the next question is whether the elevation looks like inflammation or iron overload. High ferritin alone cannot answer that. Transferrin saturation, serum iron, TIBC, blood counts, and clinical context help clarify the pattern.

Normal Range

Common adult ferritin ranges are about 30-300 ng/mL for men and about 15-200 ng/mL for women. Some references use a common 30-300 ng/mL range, while many laboratories use a lower female range because iron loss from menstruation can lower typical ferritin values before menopause. Use the range printed on your own lab report.

There is no single age chart in the supplied medical references that can be safely applied to every person. Age matters mostly through context: menstrual blood loss, pregnancy, diet, absorption, chronic inflammation, liver health, alcohol use, and medical history can all change how a ferritin value should be read.

What A High Result May Mean

Ferritin above the lab range may reflect inflammation, infection, recent surgery, tissue injury, alcohol use, obesity, metabolic syndrome, hyperthyroidism, liver disease, autoimmune disease, malignancy, lymphoma, repeated transfusions, or iron overload such as hereditary hemochromatosis.

The distinction matters. In iron overload, transferrin saturation is often elevated, commonly above about 45-50%. In inflammation, ferritin may be high while usable iron is limited. That is why a high ferritin number should not be reduced to a single explanation.

What A Low Result May Mean

Low ferritin points to depleted iron stores. The common causes include blood loss, low iron intake, poor absorption, and increased iron needs. Heavy menstrual bleeding, gastrointestinal blood loss, celiac disease, stomach surgery, and pregnancy are examples.

A ferritin below 30 ng/mL generally indicates iron deficiency. This can happen before hemoglobin falls, so a normal CBC does not rule out depleted iron stores.

Related Lab Tests To Check Together

Ferritin belongs with an iron panel and a CBC. Serum iron shows circulating iron but can change with diet and time of day. TIBC and transferrin show iron-binding capacity. Transferrin saturation, or TSAT, is calculated from serum iron and TIBC. TSAT below 20% suggests iron deficiency, while a high TSAT with high ferritin can raise concern for iron overload.

Hemoglobin tells whether anemia is present. MCV and RDW describe red blood cell size and variation. Reticulocytes show marrow response. CRP or other inflammation markers can help interpret a high ferritin result because ferritin can rise during inflammatory states.

Why Trends Matter More Than One Result

Ferritin is more useful when you can see where it has been. A ferritin of 35 ng/mL may mean something different if it was 90 six months ago than if it has been steady for years. A ferritin that falls from 15 to 8 ng/mL is a clearer sign of worsening depletion than a single isolated value.

Trends also matter for high ferritin. A value that spikes during an infection and returns toward range is different from one that stays elevated with high TSAT. Tracking the line over time helps your doctor decide whether to repeat, expand testing, or focus on a likely trigger.

When To Talk With A Doctor

Discuss ferritin with a doctor if it is below 30 ng/mL, above your lab range, changing over time, or paired with fatigue, heavy menstrual bleeding, possible gastrointestinal blood loss, abnormal liver tests, abnormal blood counts, inflammation markers, or a high TSAT.

Also ask if your result is being compared with the correct reference range. Adult male and female ranges can differ, and the lab that performed the test is the best source for the official interval used for that report.

Frequently Asked Questions

What is a common ferritin range for adult men? A common adult male range is about 30-300 ng/mL, though some labs use different limits. Use your own report's range.

What is a common ferritin range for adult women? A common adult female range is about 15-200 ng/mL. Lab methods and population differences can change the printed range.

Is ferritin below 30 ng/mL low? Ferritin below 30 ng/mL generally supports iron deficiency, even if hemoglobin is still normal.

Can ferritin be normal during inflammation? Yes. Because ferritin rises as an acute phase reactant, inflammation can make ferritin look normal or high even when usable iron is limited.

Does ferritin range change with age? Age can affect interpretation through menstrual status, pregnancy, chronic inflammation, liver health, diet, and absorption. The safest reference is the range printed on your report.

Is ferritin 15 too low? A ferritin of 15 ng/mL is below many adult reference ranges and may fit depleted iron stores. Discuss it with a doctor, especially if symptoms or blood loss are present.

What ferritin level means iron overload? Ferritin alone does not define iron overload. Doctors usually look at transferrin saturation, especially values above about 45-50%, along with ferritin and clinical context.

Which tests should I compare with ferritin? Compare ferritin with TSAT, serum iron, TIBC, transferrin, hemoglobin, MCV, RDW, reticulocytes, and inflammation markers when relevant.

How MediLens Helps Track This Over Time

Ferritin interpretation depends on pattern. MediLens helps you scan each report, store ferritin with the iron panel and CBC values, and compare results across dates. When you can see ferritin, TSAT, hemoglobin, and MCV together, a number that once felt isolated becomes part of a clearer trend.

Key Takeaways

Common adult ferritin ranges are about 30-300 ng/mL for men and 15-200 ng/mL for women.
Use the reference range printed on your own lab report.
Ferritin below 30 ng/mL generally supports iron deficiency.
High ferritin can reflect inflammation or iron overload, so TSAT and context matter.
Trends are more useful than one isolated ferritin value.
