Inherited Iron Overload Risk Test
Checks the three HFE gene variants — C282Y, H63D and S65C — behind hereditary haemochromatosis, the inherited tendency to absorb and store too much iron.
Everything you need to know about Inherited Iron Overload Risk Test
Hereditary haemochromatosis is one of the most common genetic conditions in people of Northern European descent, and one of the most under-diagnosed: iron builds up slowly over decades and the early symptoms — tiredness, joint pain, low mood, reduced libido — are easy to put down to other things. Left unchecked, excess iron can damage the liver, heart, pancreas and joints.
This test looks at the three HFE variants responsible for most cases. Knowing you carry two copies (or one of the higher-risk combinations) means your iron can be monitored with simple blood tests and, if it rises, managed very effectively. A genetic test looks at the DNA you were born with. It tells you about inherited likelihood, not certainty: a variant can raise your risk without meaning you will develop the condition, and a clear result does not remove the everyday risk everyone carries. Results are explained to you by our clinical team, and we will say when a conversation with your GP or a genetics service is the right next step.
