Ferritin Basics

Discover how ferritin tells you about iron stores and why a simple extra test can reveal hidden fatigue.

Ferritin test basics

Think of iron like cash. Haemoglobin is the money in your wallet, ready to deliver oxygen. Ferritin is the savings account. When iron drops, the body uses the savings first, so ferritin falls before haemoglobin. That’s why doctors often order ferritin alongside a full iron panel.

Normal range varies

Ranges vary by lab, sex, and age. Women usually have lower numbers because of periods and pregnancy. If you’re pregnant or on hormonal birth control, your lab may use a slightly different lower limit. Always compare your result to the range printed beside it, not a generic web value.

High ferritin threshold

A ferritin reading of three hundred or higher often signals something beyond simple iron deficiency, prompting a deeper look. This threshold can appear in chronic inflammation or liver disease, not just iron overload.

Low ferritin signs

Low ferritin can be part of the puzzle behind fatigue, breathlessness, and even extra hair in the brush. It’s not the only cause, but it’s worth checking when you feel run down. Other triggers like crash dieting, stress, or recent illness can also cause shedding, so consider the whole picture.

Inflammation masks iron

Ferritin is an acute-phase protein, so inflammation, infection, fatty liver, or obesity can push it up even if iron stores are low. A normal reading may mask a deficiency. A simple CRP test can flag this hidden inflammation, guiding you to the right follow-up.

The one tip

If your ferritin looks okay but you’re still tired or losing hair, ask your doctor to add a CRP test. CRP reveals inflammation, helping you interpret ferritin correctly.
