Vitamins are organic compounds necessary to sustain life, most taken from food. A lack of them means the number of healthy red blood cells decreases.
Why get one?
A person who has deficiencies may experience symptoms like:
Fatigue.
Breathing problems.
Dizziness.
Lack of concentration.
Irregular heart rhythm.
What are the Instructions for home use?
Please take your test samples in the morning. Take it at least one hour before any medication.
Also, here are some tips for collecting your sample:
Drink plenty of water, as being well-hydrated will make it easier to collect your sample.
Shower before you take your sample or run your hands under warm water for a few minutes, as this improves blood flow.
Do some exercise (move around, go for a walk, etc.) to get the blood flowing.
Let gravity do some of the work by keeping your arm below your heart level.
Nails that are too long can make it difficult to collect a sample.
Do not shake the sample vigorously, but invert the tube gently 10 times. (gently swirl the tube after each drop of blood)
Do not squeeze the finger.
Re-warm your hands during collection where needed.
2 Biomarkers:
B12 helps produce red blood cells, which carry oxygen around your body.
D: Measures how much D you have in your blood, essential for healthy bones, teeth, and muscles.
How does it Work?
Firstly, order your kit online and once it arrive collect your sample at home.
Then, drop off the Kit in the morning to the Royal Mail Red Street Box. Use the Track24/48 Return Label to the Lab.
Lastly, once your results are ready, we will send you an email with your Result. Also you can view the report in your Dashboard.
How long do the results take?
The target turnaround time for the b12 test for deficiency results is 1 working day from receiving them in the laboratory. A while you wait service upgrade is available for £50.
Please take your sample from Monday to Thursday to avoid delivery delays by Royal Mail over the weekend.
Please click here if you want a Clinic checkup in london for deficiency.. There are 4 locations across London to get your D or b12 checkup. This Vitamin Profile Blood test means you can get both results in 1 order, from a clinic or a home kit.
Good sample management means sending your home sample straight to the laboratory. But please do not keep it at home for several days as it probably arrived spoiled, and you must make the sample again. However, some people keep the sample for weeks and then send it to us.
Please ensure that you activate your B12 deficiency sample in your account. Then, when you take it, we can track its return.

What is the Scientific Data from Instrument and Reagent Supplier?
Technology Method:
Fluorescence quantitative immunoassay
Limit of Detection:
Vitamin B12: 20 pmol/L
Vitamin D: 5.0 ng/L
Accuracy and Precision:
The relative standard deviation from the target value is ≤ 15%. The within-assay CV is ≤ 15%. The between-assay CV is ≤ 15%.
The accuracy of these Vitamin D and B Tests is based on the relative deviation, which is the average deviation from the actual result value.
The precision relies on the within-assay coefficient of variations and the between-assay coefficient. However, the within-assay coefficient of variations is the variance of the result value if the same test is analysed again, and the between-assay coefficient is the variance of the result value if the same sample is reprocessed from the beginning again.
In range results:
Vitamin B12: 118~701 pmol/L
Vitamin D: 30.0~100.0 ng/L

Shared information from a Customer we refer to as Jenny:
What and when should they be supplemented?
Vitamin B12, or cobalamin, is a water-soluble vitamin and, as the term suggests, is soluble in water; it is only partially accumulated in the body. Therefore, it must be regularly ingested through food.
And those who follow or would like to follow a vegan or vegetarian diet may have already heard of this vitamin, as this type of diet may often require specific supplements.
With Dr Martina Anderson, nutritionist at H. Medical Care, we find out what vitamin B12 is for and where to find it.
Vitamin B12:
What is it for?
Vitamin B12 is involved in various roles, which are fundamental for ensuring perfect body functioning. In particular, it is necessary for the metabolism of amino acids and nucleic acids – together with folic acid, it assists in synthesising DNA and RNA – and fatty acids. It is also essential in the production of red cells and the formation of bone marrow. And, it also promotes the transformation of nutrients into energy and reduces stress by increasing good mood.
The nutrition
Vitamin B12 is present in foods of animal origin, where it is found in enzymatic form, therefore linked to proteins, and is made available thanks to some gastric enzymes. We find it in particular in:
meat;
fish;
liver;
milk;
egg;
The amount of vitamin B12 absorbed compared to that present in foods is 60% for meat and milk, 30-40% for fish products and, according to some studies, less than 10% for eggs. Furthermore, about a third of the vitamin is lost during cooking.
The daily requirement of vitamin B12 for adults corresponds to approximately 2-2.4 mcg, generally taken following a normal diet. However, pregnant or breastfeeding women must take a larger quantity to provide the right amount to the fetus.
What does it cause?
It is difficult for those who follow a varied and balanced diet to register a vitamin B12 deficiency; this type can occur in subjects who follow a vegan diet or when the absorption mechanism does not work well in the intestine.
In the case of malabsorption, the causes can be inflammatory diseases, malabsorption diseases (e.g. celiac disease), proliferation of bacteria, drugs, decrease in gastric acidity, especially in the elderly or absence of the intrinsic factor; the latter is, in fact, responsible for the absorption of vitamin B12.
In the case of vegan diets, the deficiency is linked to the lack of foods of animal origin that contain it.
The main consequence of vitamin B12 deficiency is a form of anaemia defined as “pernicious“, resulting from poor production of blood cells, which can cause paleness, weakness, tingling in the limbs and fatigue. In more serious cases, there can also be consequences for the nervous system.
The diagnosis is made through Vitamin blood tests: if a deficiency is suspected, the level of vitamin B12 in the blood is evaluated, and the size of the red blood cells is checked to ensure it is not too high.
Vitamin B12 deficiency should be avoided in pregnant women to avoid harmful consequences on the unborn child.
Vegan Diets
For the moment, there are no processed plant foods that could satisfy human vitamin B12 needs.
Some algae, brewer’s yeast, and some foods of oriental origin such as tempeh (derived from soybeans) and Kombucha (Chinese tea) contain vitamin B12 but in tiny proportions, useless for human needs since they are not assimilable from our organism.
For this reason, those who eat only plant-based foods need to take this vitamin through specific supplements. Consuming fortified foods, i.e., those added with vitamin B12, can also be helpful. Even in newborns of vegan mothers, it is important to start treatment with supplements immediately after birth to prevent deficiency.
What is the relationship with protein?
Vitamin B12, folates, and the vitamin C complex are fundamental as they support and help our body produce proteins. Furthermore, consider that when our body absorbs vitamin B12, it does so using stomach acid, which separates B12 from the proteins associated with foods and binds it to another molecule, facilitating its absorption.
Vitamin B12 plays a very important role in the metabolic process. Promoting the production of red blood cells and facilitating protein metabolism protects the nervous system’s integrity.
What are the symptoms and causes?
A vitamin B12 deficiency depends on poor or inadequate absorption and storage capacity. This deficiency could be avoided in vegan subjects by taking food supplements that compensate for its level.
The diagnosis is usually made by examining the results of blood tests following the appearance of symptoms such as:
Anemia;
Sense of respiratory weakness and muscle fatigue;
Tingling in the hands and feet;
Pallor;
Feeling dizzy;
Confusion;
Walking difficulties
What are the causes and symptoms of excesses?
When vitamin B12 is high, the cause can frequently be attributed to various pathologies that are very serious for our health:
Liver diseases;
Myeloproliferative disorders;
Solid neoplasms;
Kidney failure;
Alcoholism
It is important to remember that the presence of high B12 levels does not inevitably mean the presence of these diseases. Furthermore, an excess of this vitamin brings with it several symptoms of its own:
Tremor;
Swellings;
Excessive nervousness;
Rapid heartbeat;
Kidney problems
Many patients with these symptoms wonder how to lower B12 when
is so high, but it is important to remember that none of these disorders tends to last long, given that the quantity of this excess vitamin is eliminated thanks to urine.
What are the main problems linked to excess?
Nutritionists recommend a daily intake of 2.4 micrograms per adult. If we take a greater quantity of vitamin B12, our body will not be able to dispose of the excess properly, and we risk incurring the following side effects:
Heart failure: Too much vitamin B12 in our body can lead to the heart not pumping blood properly, causing episodes of heart failure. For this reason, patients with heart problems must refrain from taking excessive doses of vitamin B12 (especially in the form of injections), especially if not under close medical supervision.
Hepatic and renal failure. Both liver and kidney cells can be damaged by excess intake of this type of vitamin, causing significant damage to these two organs.
Formation of blood clots. Another negative effect of excess vitamin B12 is that it facilitates the formation of blood clots, which can become very dangerous because they impede normal blood flow. Therefore, people who are familiar with blood clots or stroke should also avoid further intake of vitamin B12.
Vision problems. It is also possible to suffer from blurred vision due to excessive accumulation of this vitamin in the body.
How to lower the levels?
An excess of vitamin B12 can lead to some contraindications. For this reason, it is important to know how to lower it by paying attention to your diet.
To counteract B12 hypervitaminosis, it is advisable to give up some foods of animal origin, such as:
Egg;
Milk and derivatives;
Meat;
Fish
It is important to reduce the consumption of legumes, soy, wheat germ and other products of plant origin that contain this vitamin.
Another key factor in correcting B12 levels is physical activity, which promotes its disposal through sweat. Drinking plenty of water to facilitate its elimination through urine is also recommended.
