Vitamin B12 is essential for normal red-blood-cell formation, nervous-system function and cellular repair. Low levels can contribute to anaemia, fatigue, weakness and neurological symptoms.
B12 is found mainly in animal-derived foods, so testing can be particularly relevant for people following a plant-based diet or anyone with a condition that may reduce vitamin absorption. The result measures the amount of vitamin B12 circulating in the blood and can support the investigation of deficiency.

What gets tested?
The biomarkers included in this profile are grouped below so you can see exactly what is being assessed.
Vitamins
Vitamins are required for normal cell function, growth and development. Measuring selected vitamins can help identify deficiencies that may contribute to common symptoms and health problems.
Vitamin B12
Vitamin B12 is required for normal red-blood-cell formation, DNA synthesis and nervous-system function. Deficiency can cause anaemia and neurological symptoms and is more common with reduced dietary intake or impaired absorption.

Your report
How do I read my results?
Laboratory results are provided with reference ranges which are based on the normal test results of a large group of healthy people from the same age group and gender as yourself.
Sometimes, healthy people get results outside the reference range, while people with health problems can have results in the normal range. If your results fall outside the reference range, or if you have symptoms despite a normal result, you may require more testing or wish to discuss the result with your GP. Alternatively you can book an appointment with one of our Private GP for £49 if you would like to discuss your results in more detail.
For simplicity, we provided your results graphically, so they are easy to understand. Any result flagged amber is outside of the standard range. Normal results are in green.
