Special instructions

Active B12 levels can be affected by use of vitamin B12 supplements. If you are taking an oral supplement then we recommend not taking it for one week prior to the test to ensure an accurate measure of your B12 levels. If vitamin B12 is being prescribed to you by your doctor then you should discuss with them how long to omit B12 supplements for.
This blood test measures levels of vitamin B12 and folate which are essential water-soluble vitamins. It also tests for levels of ferritin, an important measure of iron stores in the body. All these tests are helpful in the diagnosis of anaemia.

Vitamin B12 is a water-soluble vitamin that is found in virtually all meat products and certain algae such as seaweed that helps maintain healthy nerve cells, red blood cells and is also needed to make DNA, the genetic material in all cells. Good sources of vitamin B12 include meat, salmon, cod, milk, cheese, eggs, yeast extract and some fortified breakfast cereals. As this vitamin is found almost exclusively in animal-based products, those who cut out animal products from their diet are at risk of B12 deficiency so checking their B12 levels is very important.

Vitamin B12 deficiency symptoms usually develop gradually but can worsen if the condition goes untreated, they include headaches, fatigue, 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.

Folate is a water-soluble vitamin important for the normal production of red blood cells and in the prevention of neural tube defects such as spina bifida in unborn babies. Folate is found in small amounts in many foods. Good sources include broccoli, Brussels sprouts, asparagus, peas, chickpeas and brown rice. Other useful sources include fortified breakfast cereals, some bread and some fruit (such as oranges and bananas).

Most people should be able to get the required amount of folate by eating a varied and balanced diet with plenty of green leafy vegetables.

Both vitamin B12 and folic acid are necessary to help break down homocysteine in the body. High levels of homocysteine are thought to be a risk factor for cardiovascular disease.
