What is Vitamin B12?

Vitamin B12 is an essential nutrient that plays a crucial role in keeping our bodies healthy and energised. Often referred to as the “energy vitamin”, B12 vitamin supports red blood cell formation, nerve function, and DNA synthesis. It’s not something our bodies can produce on their own, so we rely on foods like meat, fish, and dairy products to get enough. For people following vegetarian or vegan diets, or those with certain medical conditions, getting the right levels can sometimes be more challenging.

When your body doesn’t have enough vitamin B12, it can lead to a range of symptoms, from fatigue and weakness to problems with memory and concentration. That’s why spotting a vitamin B12 deficiency early on is so important for maintaining your health and wellbeing. Left untreated, a deficiency can even contribute to nerve damage and other serious complications.

At Medilabs, we understand how important it is to have a clear picture of your vitamin levels. That’s why we offer a quick and reliable vitamin B12 blood test to help you detect any potential issues. Whether you’re experiencing symptoms or simply want peace of mind, our expert team in London is here to guide you every step of the way.

Benefits of Vitamin B12 Testing

·      Early Detection of Vitamin B12 Deficiency

A timely vitamin B12 blood test can help identify a vitamin B12 deficiency before symptoms become severe. Many people don’t realise they are lacking this vital nutrient until fatigue, memory issues, or tingling sensations appear. By uncovering low levels early, you have the chance to make simple changes and prevent long-term health problems.

 

·      Tailored Health Advice

With an accurate vitamin B12 test, you receive detailed insight into your body’s needs. This allows our team to offer clear, personalised advice, whether you need dietary changes, supplements, or further investigations. We believe that no two patients are the same, and a B12 vitamin assessment is the first step towards truly bespoke care.

 

·      Prevention of Complications

Left untreated, a vitamin B12 deficiency can lead to serious complications, such as nerve damage or anaemia. Regular testing ensures you stay one step ahead, safeguarding your long-term health. By booking a vitamin B12 deficiency test with us, you’re making a proactive investment in your wellbeing.

 

·      Peace of Mind for Vegetarians and Vegans

Plant-based diets can sometimes put individuals at risk of low B12 vitamin levels, as this nutrient is mostly found in animal products. A simple test of vitamin B12 provides reassurance, confirming your status and giving you confidence in your lifestyle choices. If a deficiency is detected, you can address it before it affects your health.

 

·      Support for Ongoing Symptoms

Unexplained tiredness, mood changes, or poor concentration can often be traced back to low B12.

Your Vitamin B12 Blood Test Results – Explained

When you receive your vitamin B12 blood test London results from Medilabs, you’ll see a number, usually measured in picograms per millilitre (pg/mL) or picomoles per litre (pmol/L). Here’s how to make sense of those values:

 

1. Normal / Healthy Range

  • 200–900 pg/mL (or 148–665 pmol/L)
    A result within this range generally means your B12 vitamin levels are healthy, and there’s no sign of a vitamin B12 deficiency. You’re likely getting enough B12 from your diet and absorption is normal.

2. Borderline/ Low-Normal

  • 200–300 pg/mL (or 148–221 pmol/L)
    This is a ‘grey area’ where levels are on the lower end of normal. While some people in this range are healthy, others may start to show mild symptoms of vitamin B12 deficiency. Further test b12 vitamin or monitoring may be advised, especially if you have symptoms.

3. Deficient / Low

  • Below 200 pg/mL (or below 148 pmol/L)
    A result in this category means you may have a vitamin B12 deficiency. This could lead to fatigue, neurological changes, or other health problems. It’s important to discuss next steps with a healthcare professional and consider follow-up tests or treatment.

4. High B12 Levels

  • Above 900 pg/mL (or above 665 pmol/L)
    Occasionally, levels above the normal range can occur, sometimes due to supplements, liver conditions, or other medical reasons. High B12 isn’t usually harmful, but it’s important to speak with our team if your b12 vitamin test shows this result, so we can assess the underlying cause.

 

Please note that these reference values may vary slightly depending on the laboratory and specific testing method used. Our expert clinicians will always interpret your results in the context of your overall health, medical history, and symptoms.

If you’re ever unsure what your vitamin B12 test results mean, our team is just a call or message away to provide clear answers and next steps.
