  • You have low vitamin B12 and wish to investigate the cause
  • You are experiencing symptoms of B12 deficiency and have an increased risk of pernicious anaemia
The Vitamin B12 Check Ultra is a profile of tests designed to thoroughly investigate a 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.

This test also examines whether autoantibodies to intrinsic factor and gastric parietal cells are present and elevated which could indicate whether an autoimmine condition (pernicious anaemia) is causing B12 deficiency.
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.
