Iron

Serum iron measures iron circulating in the blood at the moment of the draw. It gives different information from the body's stored iron.

Understanding the test

What does the Iron test measure?

Also called Serum Iron

Serum iron may be requested during an assessment of anaemia, iron treatment or possible iron overload. It is often paired with markers of storage and transport.

When it may be requested

A transport measurement

Circulating iron contributes to calculation of transferrin saturation.

An iron pattern during illness

The combination with ferritin can clarify whether low circulating iron reflects low stores or inflammatory changes.

Before your sample

Prepare for collection

SpecimenSerum
Your checklist0 of 2 ready

Choose a fasting morning draw if possible. Meals and recent iron doses can change this circulating measurement; ask the clinician how to time an iron supplement.

A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result

The value varies through the day and after food or supplements. Ferritin and transferrin saturation help distinguish transient variation from a change in iron status.

What can affect it

  • Meals, supplements and timing can affect serum iron substantially.

Discuss the next step

Note the collection time, last meal and last iron supplement, then compare the result with ferritin or binding capacity if available.

Patient questions

Before you book

Why take note of a recent iron supplement?

A recent dose or meal can change circulating iron. Give the team the time of your most recent dose and follow its instructions for your particular order.

Why does this test have to be done in the morning?

Serum iron varies during the day, so a similar morning collection time makes two results easier to compare. A meal or a recent iron supplement can still affect the measurement. Tell the team when you last ate or took iron.

What does a high serum iron level mean?

Most often it follows an iron tablet, multivitamin or infusion taken shortly before the sample. Less commonly it points towards iron overload, such as hereditary haemochromatosis or repeated blood transfusions, or reflects liver injury or red cell breakdown releasing iron into the blood. A repeat fasting morning sample with ferritin and transferrin saturation helps tell these apart.
