What is it?
An essential vitamin for nerve function, red blood cell production and DNA synthesis.
Why it matters for long-term health
Deficiency causes irreversible nerve damage if untreated. Easily missed — symptoms overlap with stress and fatigue.
Longevity and healthy ageing
Adequate B12 protects cognition, mood and energy as we age.
What a high result may indicate
Usually due to supplementation; rarely liver disease or myeloproliferative disorder.
What a low result may indicate
under 200 pg/mL deficient; 200–300 borderline — check methylmalonic acid.

Frequently asked questions
Can I have a Vitamin B12 blood test at home in Dubai?+
Yes — our DHA-licensed nurse draws Vitamin B12 at your home, hotel, villa or office anywhere in Dubai, usually within 60–90 minutes of booking. Your result is then reviewed by a British-trained GP who calls you to explain it in plain English.
Do I need to fast before a Vitamin B12 test?+
Most patients do not need to fast for Vitamin B12 specifically. If we are running a fuller panel (lipids, glucose, insulin) we will advise an overnight fast — our team confirms this when you book.
How quickly will I get my Vitamin B12 result?+
Standard turnaround is 24–48 hours from a DHA-accredited laboratory. Your named British GP then calls you personally with the interpretation and a written wellness plan — not a PDF you have to decode alone.
Is Vitamin B12 covered by insurance?+
Most premium UAE and international insurers reimburse — we provide a fully coded invoice at the visit. Reimbursement typically arrives within 5–10 working days.
