Ferritin (Iron Levels) Blood Test

What is a Ferritin (Iron Levels) Blood Test?

Your body needs iron to produce healthy red blood cells and transport oxygen throughout your system. Ferritin is a protein that stores iron in your body, and measuring ferritin levels gives a clear picture of your overall iron stores.

A Ferritin Blood Test can detect:

• Iron deficiency (a common cause of tiredness and anaemia)

• Early signs of iron deficiency anaemia

• Iron overload (which can damage organs)

• Causes for symptoms like tiredness, breathlessness, or paleness

Why is this Test Important?

Iron is essential for producing haemoglobin—a crucial protein in red blood cells. If your iron stores are low, your body struggles to make enough healthy red blood cells, which can lead to anaemia and leave you feeling unwell. Low iron levels can be caused by a poor diet, chronic disease, blood loss (such as heavy periods), or digestive disorders affecting absorption.

A Ferritin Blood Test can help:

• Pinpoint causes of fatigue and weakness

• Detect iron deficiency before anaemia develops

• Monitor treatment for iron deficiency anaemia

• Detect iron overload in conditions such as haemochromatosis

What Symptoms Might Indicate You Need This Test?

You may benefit from an iron (ferritin) blood test if you notice:

• Persistent tiredness or fatigue

• Unexplained weakness

• Pale skin

• Shortness of breath, especially during activity

• Palpitations or rapid heart rate

• Hair loss or brittle nails

• Frequent infections

If iron overload is suspected, symptoms can include joint pain, abdominal pain, weakness, or unexplained changes in liver function.
