Anaemia

Iron

In short

  • Iron is an essential mineral needed for the production of haemoglobin and the transport of oxygen throughout the body.
  • Your body obtains iron from food and uses it to produce red blood cells and support normal energy metabolism.
  • An iron deficiency can cause symptoms such as fatigue, dizziness, shortness of breath, headaches and reduced concentration.
  • Iron levels that are too high or too low can have various causes and do not always cause symptoms directly.
  • An anaemia test can measure and assess the amount of iron in the blood.
  • Iron is often measured together with ferritin and haemoglobin to provide a more complete picture of your iron status.
  • Measuring iron can help investigate anaemia, persistent fatigue or a suspected iron deficiency.
  • Would you like to know whether your iron level is within the normal range? An anaemia test can provide quick and reliable insight.

What is iron and what role does it play in the body?

Iron is an important mineral that your body needs to function properly. It is mainly found in your blood, where it helps transport oxygen to all parts of your body. Iron is also needed for the production of certain proteins and for the proper functioning of your muscles and immune system.

What does a low or high iron level mean?

A low iron level means that your body does not have enough iron. This is also known as iron deficiency and can lead to anaemia. A high iron level is less common but can be harmful because excess iron can accumulate in organs such as the liver and heart.

What symptoms can be associated with an abnormal iron level?

If your iron level is too low, you may feel tired, weak or dizzy. You may also experience headaches, pale skin, shortness of breath or heart palpitations. If your iron level is too high, you may experience abdominal pain, joint problems, fatigue or a brownish discolouration of the skin. Sometimes high iron levels cause no noticeable symptoms for a long time.

What can cause iron levels to increase or decrease?

Iron levels can be low due to blood loss (for example, from menstruation or bleeding), insufficient iron in your diet, or because your body does not absorb iron properly. Iron levels can be elevated due to inherited conditions (such as haemochromatosis), excessive use of iron supplements, or certain liver diseases.

When should you consider having your iron level measured?

It may be advisable to have your iron level measured if you have symptoms that could indicate iron deficiency, such as fatigue, pale skin or shortness of breath. It may also be useful to have your iron checked if you experience significant blood loss, are pregnant or have a chronic condition.

How is iron measured and how should you interpret the result?

Iron is measured using a finger-prick blood test. Often, not only iron itself is measured, but also other related values, such as ferritin (iron stores) and transferrin (the protein that transports iron). Your doctor compares your result with the normal reference values. If your iron level is too low or too high, your doctor can discuss what this means for you and whether anything needs to be done.

What conditions can be associated with an abnormal iron level?

A low iron level can be associated with anaemia, chronic blood loss or problems absorbing nutrients (such as coeliac disease). A high iron level can occur with haemochromatosis (an inherited condition), liver disease or excessive use of iron supplements.

How can an abnormal iron level be improved or treated?

If your iron level is too low, you can eat more iron-rich foods, such as red meat, green leafy vegetables, legumes and nuts. In some cases, your doctor may prescribe iron supplements. If your iron level is too high, it is important not to take additional iron, and your doctor may recommend treatments such as phlebotomy (removing blood) or medication. Treatment depends on the underlying cause of the abnormal level. Always discuss the most appropriate approach with your doctor.
