Within the iron and ferritin range at Wimpole Street, the Transferrin is the test to consider when the question concerns iron transport, liver function and anemia detection. It costs £98, and once the Marylebone clinic opens on 1 October 2026 a nurse or phlebotomist takes the venous blood sample (serum), with the laboratory typically reporting in 1 day. Medical services are for patients aged 16 and over, self-referral with no GP referral needed, and the laboratory report is delivered to your secure portal.

What Transferrin measures
Transferrin is most often requested in connection with iron transport, liver function and anemia detection, which is why it sits within the iron and ferritin group at Wimpole Street.
Iron studies look at how much iron is stored (ferritin), how much is in transit (serum iron and transferrin) and how full the transport protein is (transferrin saturation, calculated from iron and total iron-binding capacity). Ferritin on its own is the most widely used single measure of iron reserves. The same panel is used in reverse to look for iron overload, where stores are too high rather than too low.
Preparing for your Transferrin
- 1A morning sample after an overnight fast gives the most reliable serum iron and saturation, because iron in food raises levels for a few hours.
- 2Do not take an iron tablet on the morning of the test; take it afterwards.
- 3Mention any recent infection or inflammation, as ferritin climbs during illness and can mask low stores.
Sample for this test: venous blood sample (serum).
Who considers Transferrin
- People often consider iron testing if they feel exhausted, short of breath on stairs or notice their heart racing more than usual.
- Heavy periods, pregnancy planning or a recent birth are common reasons for checking stores.
- Runners and endurance athletes frequently monitor ferritin because training increases losses.
- Anyone eating little red meat, or donating blood regularly, may wish to know whether reserves are keeping up.
- A family history of haemochromatosis, or unexplained joint pain and fatigue, can prompt a check for overload instead.
Understanding your Transferrin results
Low ferritin with low transferrin saturation typically indicates depleted iron stores, while a low haemoglobin alongside it suggests the shortage has progressed to anaemia. Ferritin above the reference range may reflect inflammation, liver strain or genuine overload, and transferrin saturation helps to separate these. Because ferritin is also an inflammation marker, a clinician interpreting your report will want to consider your CRP and history before suggesting a next step.
Iron results are influenced by recent meals, inflammation and time of day, so borderline values are often repeated under standardised conditions before any change is made.
