Wimpole Street, Marylebone
People looking into iron storage protein and kidney function in Marylebone are usually looking for the Haemosiderin (Urine). It belongs to our iron and ferritin group and needs an early morning urine sample, which a nurse or phlebotomist collects at 22 Wimpole Street, Marylebone once the clinic opens on 1 October 2026. The laboratory typically returns a result in 2 weeks, and the standard price is £128 with no members’ tier.

What Haemosiderin (Urine) measures
The catalogue tags the Haemosiderin (Urine) with iron storage protein, kidney function and urine test. Those terms describe the territory the test covers; the notes below explain what an iron and ferritin result can and cannot tell you.
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 Haemosiderin (Urine)
- 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: early morning urine sample.
Who considers Haemosiderin (Urine)
- 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 Haemosiderin (Urine) 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.
