Why get tested?
To find out whether your blood iron level is normal

When to get tested?
If your doctor thinks that you might have too little or too much iron in your blood. Low iron can cause anaemia, and is usually due to long-term or heavy bleeding, pregnancy, or rapid growth (in children); rarely is it due to poor diet. A high iron level can be due to a genetic condition, extensive blood transfusions, or rarely due to ingestion of an overdose of iron (usually in children).

Sample required?
A blood sample taken from a vein in your arm
