Low Iron Stores Linked to Fatigue and Hair Loss: Ferritin Blood Testing in High Demand at Leading London Clinic

London, UK – With growing public awareness around the limitations of routine iron panels, a rising number of patients in the capital are turning to London Blood Tests for targeted ferritin blood testinga crucial yet often overlooked marker for iron storage, chronic fatigue, and low energy.

Unlike general iron tests that measure what’s circulating in the blood, a ferritin blood testevaluates the body's iron reserves. Ferritin, a protein that stores iron, can reveal hidden deficiencies or inflammatory patterns that go undetected in standard screenings. At London Blood Tests, clinicians report that ferritin testing is now one of the most requested investigations among patients experiencing unexplained fatigue, hair loss, poor immunity, or difficulty concentrating.

“Many patients arrive at our clinic having been told their blood tests are ‘normal,’ yet they still feel unwell,” says Gabriela Brewer, founder of London Blood Tests. “Ferritin on a blood test often provides the missing piece. It allows us to identify low iron storage long before anaemia develops and help patients take action before symptoms escalate.”

Clinicians at the London-based facility highlight that blood test ferritin results can also point to underlying inflammation or liver stress when elevated making it a valuable marker in complex diagnostic cases. Women, athletes, and individuals with high stress levels or plant-based diets are among the groups most commonly affected by depleted ferritin levels.

With fast turnaround, clear result interpretation, and no GP referral required, London Blood Tests continues to support proactive patients who want answers without delay. The clinic offers a discreet, same-day ferritin blood test UK service with appointments available throughout the week.
