Bluecrest crestActive Vitamin B12 Home Test Kit


Vitamin B12 is an important vitamin that is required by the body to keep blood cells and the nervous system healthy. Vitamin B12 is acquired solely through diet as it comes from animal produce such as meat, dairy and fish. Therefore, strict vegetarians and vegans are at higher risk of vitamin B12 deficiency, as well as adults over 50, women, and people with other autoimmune conditions such as rheumatoid arthritis and Graves’ disease.

Bluecrest’s active vitamin B12 test is suitable for all adults, and may be particularly useful for people at increased risk because of their diet or because of medical conditions such as the ones mentioned above.

What is an Active Vitamin B12 Test?

There are two forms of vitamin B12 – ‘active’ and ‘inactive’. The active form can be used by the body, whereas the inactive form cannot. This means that testing general levels of vitamin B12 has its shortcomings since a blood test can show normal levels of vitamin B12 even though the body may not be able to use much of it. Bluecrest’s vitamin B12 test measures the amount of active vitamin B12 in order to avoid such potential misdiagnosis. Thus it provides an accurate view of how much vitamin B12 is available for your body to use. This test can be done in the comfort of your own home as it simply involves taking a blood sample with an at-home finger prick kit.

Frequently Asked Questions

  • Can B12 deficiency cause dizziness?

    Vitamin B12 deficiency can cause a variety of symptoms,  including:

    •       Tiredness
    •       Pins and needles
    •       Muscle weakness
    •       Mouth ulcers
    •       Ringing in the ears (tinnitus)
    •       Memory problems
    •       Depression
    •       Change in mobility and vision

    It is essential to note that such symptoms could also indicate many other health conditions.

  • How much vitamin B12 do you need?

    Adults aged between 19 and 64 need around 1.5 micrograms of vitamin B12 per day.

    In the absence of underlying medical conditions, this should be easily reached with a balanced  diet that includes animal produce. However, vegans and vegetarians may need supplements to get an adequate amount of vitamin B12.

  • What do the results of an active vitamin B12 test mean?

    Levels of vitamin B12  that are higher or lower than the normal ranges do not always indicate that there is an underlying health issue. But any abnormal result should be discussed with your GP to assess whether there is an associated health condition.

    Low levels of Vitamin B12 can lead to anaemia and produce a wide variety of symptoms. Low levels may be a sign of a lack of B12 in the diet or a medical condition affecting its absorption. High levels can be a sign of liver disease or certain blood cancers.

  • How can you manage your vitamin B12 levels?

    Although most B12 deficiencies are caused by an underlying health condition, there are preventative measures that can be taken to avoid deficiencies:

    • Diet: try incorporating more seafood, fish, meat, fortified soy milk and dairy products into your diet to help ensure you are getting a sufficient amount of vitamin B12.
    • Supplementation: People following a strict vegetarian or vegan diet will need to get three micrograms of B12 through eating foods that have been fortified with B12. These foods include some breakfast cereals, soya products and marmite. Alternatively a B12 supplement of at least ten micrograms per day can be taken.

    If your levels of vitamin B12 are abnormal due to an underlying health issue, your GP will need to treat that condition first.

  • What is the difference between vitamin B9 and B12?

    Vitamin B9, also known as folate or folic acid, is often grouped with vitamin B12 as they both have similar functions, and vitamin B12 helps the body use vitamin B9. As for vitamin B12, folate helps the body to form healthy red blood cells. It also has an important role in reducing the risk of certain birth defects such as spina bifida.
