Vitamin B12 Check

About this test

Vitamin B12 is transported in the blood bound to proteins - it is only the vitamin B12 that is bound to holotranscobalamin that is active in our cells. This test measures both active B12 (which represents about 20% of total B12) and total B12 to give a thorough picture of B12 status. 

Who is this test for?

This test is for individuals who wish to check or monitor their vitamin B12 levels. It is useful for people who may have had normal vitamin B12 results but are still suffering symptoms.

Vitamins

Vitamin B12 is important for production of red blood cells which carry oxygen around the body - low levels can cause anaemia with associated symptoms of lack of energy and fatigue. It is also involved in metabolism and the nervous system and prolonged lack of vitamin B12 may cause nerve damage. Vitamin B12 is almost entirely found in animal foods. 

Raised levels of vitamin B12 can indicate a blood or liver disorder.

Low levels are seen in people with pernicious anaemia, an autoimmune disease which prevents the absorption of vitamin B12 or through dietary restriction e.g. a vegan diet.
