Overview of the Iron Status Test
The Iron Status test is a five-marker blood profile providing a detailed assessment of circulating Iron, Iron storage and the proteins responsible for transporting Iron through the bloodstream.
Testing Iron alone can be difficult to interpret because circulating Iron varies during the day and can be influenced by food intake, supplements, inflammation and other physiological factors.
This profile therefore combines Iron with Ferritin, Total Iron Binding Capacity, Transferrin and Transferrin Saturation.
Ferritin provides information about stored Iron, while Transferrin and TIBC help assess the blood's Iron-carrying capacity.
Transferrin Saturation calculates how much of the available Iron-transport capacity is currently occupied.
Looking at these markers together provides substantially more information than Ferritin or serum Iron alone.
The Iron Status test costs £169.
Professional blood collection is available in clinic for an additional £35 or through an at-home phlebotomy visit for an additional £60.
What Does the Iron Status Test Check?
The Iron Status profile measures 5 biomarkers covering Iron storage, circulating Iron and Iron transport.
Ferritin
Measures the body's principal Iron-storage protein and provides information about available Iron reserves.
Iron
Measures the concentration of circulating Iron in the blood at the time of collection.
Total Iron Binding Capacity
Measures the total capacity of circulating proteins, principally Transferrin, to bind Iron.
Transferrin
Measures the principal protein responsible for transporting Iron through the bloodstream.
Transferrin Saturation
Calculates the proportion of available Transferrin Iron-binding sites that are occupied by Iron.
Who May Benefit From the Iron Status Test?
The profile may be useful where Iron deficiency, abnormal Iron handling or excessive Iron accumulation is being considered.
People with persistent fatigue or weakness - Iron deficiency is one possible contributor to low energy.
People with previously low Ferritin - A complete Iron profile provides more context than Ferritin alone.
Women with heavy menstrual bleeding - Ongoing blood loss can reduce Iron stores.
People with suspected Iron-deficiency anaemia - Iron studies can complement a Full Blood Count.
People with dietary restrictions - Reduced Iron intake can increase the risk of deficiency.
People with gastrointestinal conditions affecting absorption - Iron deficiency can occur when absorption is impaired.
People taking Iron supplements - Testing can help assess current Iron status and reduce unnecessary supplementation.
People with unexpectedly high Ferritin or Iron results - Transferrin Saturation and TIBC can provide important additional context.
How to Prepare
Do not stop medically prescribed Iron replacement without advice from the clinician responsible for your treatment.
Acute infection or inflammation may affect Ferritin interpretation.
Symptoms and Reasons to Consider the Iron Status Test
Iron imbalance can produce a range of symptoms, although many are non-specific.
Persistent tiredness - Low Iron availability can reduce normal oxygen delivery and energy metabolism.
Dizziness or weakness - These can occur with Iron deficiency or anaemia.
Shortness of breath on exertion - Anaemia is one possible cause and requires appropriate assessment.
Pale skin - Can occur where Iron deficiency has progressed to anaemia.
Hair thinning or increased shedding - Low Iron stores may be relevant in some people.
Reduced exercise tolerance - Iron deficiency can affect physical performance.
Restless legs - Low Ferritin can sometimes be associated with restless-leg symptoms.
Heavy menstrual periods - Recurrent blood loss is a common cause of Iron depletion.
Iron symptoms overlap with many other medical conditions.
A Full Blood Count is often useful alongside Iron studies when anaemia is suspected.
High Ferritin does not automatically indicate Iron overload because Ferritin can also increase with inflammation, liver disease and other conditions.

Occasional repeat analysis or sample issues can extend reporting.
Understanding Your Results
Iron markers are most useful when interpreted together.
Low Ferritin commonly indicates reduced Iron stores.
Low circulating Iron together with increased TIBC and low Transferrin Saturation can support Iron deficiency, although the complete pattern and clinical context matter.
Ferritin can increase during inflammation, which means a Ferritin concentration within or above the reference range does not always exclude restricted Iron availability.
Raised Transferrin Saturation may require further assessment where excessive Iron accumulation is suspected.
A Full Blood Count, inflammatory markers, liver tests or genetic testing may be recommended depending on the pattern.
Why Book With London Blood Tests?
London Blood Tests provides a complete Iron profile rather than relying on one isolated measurement.
Five Iron biomarkers - Storage, circulating Iron and transport are assessed together.
Ferritin included - Iron reserves are measured.
Transferrin and TIBC included - Iron transport capacity is assessed.
Transferrin Saturation included - The proportion of Iron-binding sites currently occupied is calculated.
Useful for deficiency and overload assessment - The complete pattern provides broader information.
Flexible phlebotomy - Choose in-clinic collection for +£35 or an at-home phlebotomist for +£60.
Fast turnaround - Results are generally expected within approximately one working day.
Clear pricing - The Iron Status test costs £169, with collection charged separately.
