From the expert

The Advanced Vitamin B12 Blood Test is a profile of tests designed to thoroughly investigate vitamin B12 deficiency. Not only does it examine the levels of active vitamin B12 in the blood, it includes a full blood count to identify whether a lack of vitamin B12 is affecting the size of the red blood cells (which affects their oxygen carrying capacity), as well as tests for folate (vitamin B9) and ferritin (iron status) which can cause similar symptoms.

Vitamin B12 is an essential water-soluble vitamin that is found in virtually all meat products and certain algae such as seaweed. It helps maintain healthy nerve cells and red blood cells and is also needed to make DNA, the genetic material in all cells.

The human body stores several years' worth of vitamin B12, however, those with pernicious anaemia, vegetarians, vegans and those who have recently had gastric bypass surgery are all at a greater risk of a vitamin B12 deficiency. Vitamin B12 deficiency symptoms usually develop gradually but can worsen if the condition goes untreated, they include headaches, feeling faint, pale skin and palpitations. Pernicious Anaemia (an autoimmune condition) prevents absorption by stopping the production of intrinsic factor and is the leading cause of Vitamin B12 deficiency.
