About the Vitamin B12 (Total)

The Vitamin B12 (Total) is an individual blood test offered at Medical and Dental in Central London. A venous blood is collected by a registered nurse during an appointment lasting approximately 20 minutes. Results are typically available within 1 day" and are delivered securely via email.

Vitamin B12 (cobalamin) is a water-soluble vitamin that is essential for the formation of red blood cells, neurological function, and DNA synthesis. It is primarily obtained from animal-derived foods including meat, fish, dairy, and eggs. The body stores vitamin B12 in the liver, and deficiency may take years to develop. When levels fall below the normal range, it can lead to megaloblastic anaemia and neurological changes. Individuals following a vegan or vegetarian diet, those over 50, and people with gastrointestinal conditions that affect absorption may be at higher risk of deficiency. A blood test measures the circulating level of B12 in the bloodstream.

Who May Consider This Test

The Vitamin B12 (Total) may be relevant for a range of individuals. The following are common reasons people choose to have this test:

  • Individuals following a vegan or vegetarian diet
  • People over 50, as absorption can decrease with age
  • Those experiencing persistent fatigue or low energy
  • Individuals with gastrointestinal conditions affecting absorption
  • People taking long-term proton pump inhibitors (PPIs) or metformin
  • Anyone experiencing tingling, numbness, or cognitive changes
