About this test

What is the Vitamin B12 test?

Vitamin B12 is a key vitamin that works alongside folic acid or Vitamin B9 to ensure your blood and nerve cells are healthy. Vitamin B12 works with enzymes to process proteins, carbohydrates, and fats, to control the energy you produce. Eggs, milk, cheese, and fish, particularly shellfish are a good source of vitamin B12.

A lack of vitamin B12 (a vitamin B12 deficiency) can result in a wide range of symptoms including rashes, mouth sores, memory loss, and depression. You may be more at risk if you are vegan, drink heavily, are over 50, or experience any digestive problems.

A high intake of folic acid can hide a vitamin B12 deficiency. If a vitamin B12 deficiency is left undetected, it can cause neurological damage. If you have been suffering from the symptoms listed above or have any concerns about your vitamin B12 levels, a Better2Know test could be for you.

What is the Better2Know testing process?

The Better2Know vitamin B12 test requires a small blood sample which can be taken at a clinic of your choice. This will be collected from your arm. Once the blood sample is taken, we will send it directly to our accredited country laboratory for analysis.

How will I receive my test results?

We pride ourselves on our quick turnaround time, the results of your vitamin B12 test will be available within one day of your sample arriving at our country accredited laboratory. Better2Know handles your results with the strictest confidence and your results will be available to access online as soon as they are ready via a secure patient login area on the Better2Know website.

What should I do when I receive my results?

If your vitamin B12 test reveals a deficiency in this vitamin, do not hesitate to contact our team to arrange an appointment with a Better2Know doctor or nutrition specialist, or you can contact your own GP. Our friendly health advisors can facilitate the arrangement of a face to face doctor's consultation or call before or after your test once you have received your results. Some of the health problems resulting from a vitamin B12 deficiency can be irreversible if left undetected, so an early diagnosis is important with the longer it goes untreated, the greater the risk of more permanent damage.
