What's tested?

This test measures the amount of iron carried in your blood and how much iron is stored in your body.

Iron is important in making red blood cells which carry oxygen around your body. It also helps keep your muscles healthy, supports your immune system, and helps your organs work properly. Low iron levels can lead to tiredness, lightheadedness and fatigue.
Shows the amount of iron in your blood. Lower levels can mean you have iron deficiency anaemia, whereas high levels can suggest liver problems.

A protein produced by the liver that transports iron around your body.

Depending on your results, restoring low iron levels can take up to 6 months. That’s why it can be helpful to test regularly to monitor your progress.

If you have too much iron in your body, it gets stored in organs like your liver, heart and pancreas. This build-up of iron can cause heart problems, joint pain and liver disease. Luckily, there are treatments that can reduce the amount of iron in your body and lessen the risk of long-term damage.

If your iron levels are below the normal range, you may be at risk of iron-deficiency anaemia. Symptoms of iron-deficiency anaemia include:

  • tiredness
  • lack of energy
  • headaches
  • difficulty concentrating
  • nail problems
  • restless legs 

If our test finds your iron levels are too low, we'll let you know right away and recommend you make an appointment with your GP.
