Personalise your Active B12 test
UKAS Accredited lab analysis
Feeling tired and weak? Check your vitamin B12 levels with our home blood test kit. A lack of active B12 can cause lethargy and fatigue and this test will give you a quick and accurate result.

B12 is essential for the formation of healthy red blood cells. Low levels of this essential vitamin can leave you feeling tired and weak, while prolonged deficiency can lead to anaemia. B12 is absorbed through diet, mainly animal sources such as meat, fish and diary. Deficiency can therefore be common amongst those following a plant based diet and also pregnant women as their requirement will increase. A recent study found 1 in 12 women under 39 to be B12 deficient.
This test includes four key markers which are crucial in assessing your iron status. Iron helps to maintain a healthy immune system, aids energy production and is essential for the production of healthy red blood cells. Low levels of iron will result in fatigue and eventually lead to iron deficiency anaemia.
This test includes three key markers which are essential for maintaining strong bones; vitamin D, magnesium and calcium. Those at greater risk of poor bone health include athletes, particularly those involved in low impact sports and women over 45 due to the onset of the menopause.
Calcium is important in helping to build and maintain strong bones and teeth. Too little calcium can lead to an increased risk of bone fractures and oesteoporosis. Calcium absorption can be inadequate due to low vitamin D and fluctuations in hormones.
Cortisol is a steroid hormone which is essential for survival and helps the body use sugar and fat which can be converted into energy. It is often referred to as the fight or flight hormone as levels rise in response to stress. Consistently high levels can lead to high blood sugar levels, muscle weakness and weight gain.
Creatine Kinase is an enzyme found mainly in the brain, skeletal muscles and heart. It has an important role to play in energy production and muscle contraction. A creatine kinase test is useful in detecting muscle inflammation and damage.
Measure three key female fertility hormones: oestrodial, FSH and LH. A useful test for women who are either trying or planning to have children, or those who want to check their levels as they transition through the menopause.
A ferritin test measures the amount of iron stored in the body and is critical in keeping the body's iron level balanced. Low ferritin levels are often caused by iron deficiency which can make you feel tired and weak and lead to anaemia.
Folate (also knowns at vitamin B9) plays an important role in the formation of new healthy red blood cells. Folate is closely linked to vitamin B12 and iron, low levels of which can make you feel tired and lead to anaemia.
Follicule stimulating hormone (FSH) is an important fertility hormone and regulates the function of the reproductive system in both men and women. Low levels of FSH can therefore cause fertility problems in both men and women and can indicate a malfunction in the ovaries or testes. FSH levels rise in women as they transition towards the menopause.
A full blood count test measures the components of blood including red and white blood cells and platelets. The test includes the measurement of haemogloblin and haematocrit vital for carrying oxygen around the body. This is a useful test for identifying the cause of dips in energy and assessing your immune function.
High sensitivity c-reactive protein (hs-CRP) is a measure of the general level of inflammation within the body. High levels are associated with increased risk of developing cardiovascular disease and stroke.
This lipid panel measures both 'good' HDL cholesterol and 'bad' LDL cholesterol together with total cholesterol and triglycerides. If your body has more cholesterol than it needs, it can build up on the artery walls increasing your risk of developing heart disease.
Magnesium is an essential trace element supplied to the body through diet. It is important in maintaining good health and performs a wide range of functions including maintenance of strong bones, keeping blood pressure normal, muscle contraction and energy production.
Oestradiol (oestrogen) is a steriod hormone and plays a key role in the reproductive, cardiovascular and bone health of females. Levels will naturally reduce in women with age and will start to decrease during the peri-menopause stage. Low levels can cause mood swings, fatigue and a decrease in bone density leading to an increased risk of oesteoporosis.
Omega 3 and 6 are fatty acids that play a vital role in reducing the risk of inflammation and, in turn, protecting your body against heart disease. It is important to get the balance between each fatty acid right. Unfortunately, far too many of us have diets that contain too much Omega 6 fatty acid (up to 10 times more) which puts the body at an increased risk of heart disease and type 2 diabetes.
Progesterone is a female hormone which is primarily produced during ovulation. If taken at the correct time in the menstrual cycle (day 21), this test is used to indicate whether ovulation has occurred.
Prolactin is a hormone produced by the pituitary gland. Slight increases can occur as part of a stress reaction. However, if your level is consitently high this can cause supression of other pituitary hormones such as FSH and LH. High levels are expected during breat feeding as main role of prolactin is to produce milk.
Check you thyroid is functioning correctly by testing the body's three main thyroid hormones: TSH, FT4 and FT3. It is estimated that 1 in 20 people have some kind of thyroid problem, with a higher incidence amongst women. Problems with your thyroid function can lead to fatigue, weight gain, mood swings and difficulty in sleeping.
A thyroxine (T4) test is used to check that the thyroid is performing properly. An overactive thyroid can cause too much thyroxine to be released into the bloodstream. Whilst an underactive thyroid can lead to too little thyroxine being produced which can cause a decrease in your metabolic rate resulting in weight gain and fatigue.
This tests measures the amount of total testoterone in the body. Low testosterone levels in men can lead to poor libido, reductions in energy and lack of motivation to train. While high testosterone levels in women can often be caused by a condition known as Polycystic Ovary Syndrome. High levels in men are particularly beneficial in sports which require strength. Levels in men will decline with age.
Vitamin D plays an essential role in our health including the development and preservation of healthy bones, boosting our immune system, our muscle function, energy levels and helping to reduce inflammation. Most of the body's vitamin D is produced in the skin following exposure to sunlight, so people living in the UK are more prone to be deficient in this vital vitamin.
