Vitamin B12 (Total) – Private Testing in London
The Vitamin B12 (Total) is available at Wimpole Street Medical and Dental, our CQC-registered clinic in Marylebone, London W1G. This test is priced at £66. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample, and results are typically available within 1 day.
Vitamin B12 (cobalamin) is essential for nerve function, red blood cell formation, and DNA synthesis. Deficiency can cause macrocytic anaemia and irreversible neurological damage if untreated.
Who Should Consider the Vitamin B12 (Total)?
Vegetarians, vegans, and those with restricted diets (B12 is found almost exclusively in animal products). Older adults, as absorption decreases with age. Those with fatigue, tingling, numbness, memory problems, or anaemia. Patients taking metformin or proton pump inhibitors long-term.
Active B12 (holotranscobalamin) measures the fraction available for cellular uptake and is a more accurate marker than total B12, particularly for borderline deficiency.
A trained nurse collects the blood sample by standard venepuncture, a straightforward procedure that typically takes around five minutes. Our clinic is on Wimpole Street, directly opposite Wimpole Street tube station (Piccadilly, Circle, and District lines). No GP referral is needed — book online or call 020 7183 0692.
