Monitor iron deficency anaemia (low iron levels)

Monitor and improve your iron levels with a home blood test, personalised insights, and GP advice.

What is iron deficiency anaemia?

Iron is a nutrient that helps transport oxygen around your body. If you don’t get enough iron, it can lead to iron deficiency anaemia. Your iron levels can drop if:

  • your diet is low in iron — vegan and vegetarian diets are sometimes low
  • you have a gastrointestinal disorder — like coeliac disease or Crohn’s disease

Heavy periods can also cause your levels to drop.

Symptoms of iron deficiency anaemia

If you have iron deficiency anaemia, symptoms can include:

  • extreme tiredness and weakness
  • pale skin 
  • shortness of breath
  • dizziness
  • heart palpitations

Long-term, iron deficiency anaemia might lead to issues like an irregular heartbeat or an increased susceptibility to infections.

Monitor your iron levels with a blood test

A blood test can help you track your iron levels and improve your health.

Arrow

Ferritin

Ferritin stores iron and releases it when your body needs it. So your ferritin levels are a useful indicator of your body's iron status. Low levels can indicate that you have iron deficiency anaemia.

Arrow

Total iron binding capacity

A total iron-binding capacity (TIBC) test measures your blood's capacity to bind and transport iron. This can help indicate if you’re deficient in iron.

Arrow

Transferrin saturation

Transferrin is a protein that transports iron around the body. A transferrin saturation test measures the amount of iron bound to transferrin. This helps check for iron deficiency.

Arrow

Unsaturated iron binding capacity

Unsaturated iron-binding capacity (UIBC) is the amount of iron binding sites on transferrin (transports iron around your body) that aren't bound to iron. If you’re deficient in iron, your UIBC will be high.
