Who should take the test?

Vitamin D deficiency is prevalent in our region, particularly during the winter months when the limited exposure to UV light impedes the body’s ability to produce an adequate amount of this essential nutrient. Insufficient vitamin D levels can lead to significant health repercussions.

People who rarely spend time outdoors are at increased risk of a deficiency. This includes, above all, chronically ill, elderly people or people in need of care. Elderly people are also particularly at risk, as their own production of vitamin D declines with age. Risk groups also include people with chronic gastrointestinal, liver or kidney diseases, as they often have poor vitamin D utilization.

The test analyzes your vitamin D level and helps you determine whether you need additional vitamin D, e.g. as a dietary supplement.

How does it work?

Once your order has been processed, you will be sent a blood sample collection kit. You collect your sample from the comfort of your own home and send it right back to our CLIA-certified partner laboratory. We analyze your sample and inform you that your results have been uploaded to your confidential account on our secure website.

What guidance will I get along with my results?

Following the completion of the analysis, you will receive a lab report that includes explanations for the analyzed markers and details on potential symptoms linked to imbalances. Additionally, we strongly advise that you discuss the results you receive from us with your healthcare provider or practitioner.

Moreover, additional information can be found on our website, particularly within various test categories, “health conditions,” and the Frequently Asked Questions (FAQs) section. If you have any further inquiries, please feel free to reach out to us by sending an email to

Test measures
For the Vitamin D Test we analyze:
  • Vitamin D
Vitamin D

Vitamin D describes a group of fat-soluble vitamins of which vitamin D3 is the most important type for humans. Vitamin D plays an important role in bone mineralization by supporting the intake of calcium from the intestines and installation into the bones. Moreover, Vitamin D is involved in important metabolic processes and in the formation of proteins. It can either be produced by the body itself or ingested with food. A sufficient provision through foods is difficult though because only a few foods contain a considerable amount of vitamin D.

People who spend little time outdoors have a higher risk for vitamin D deficiency. This especially includes people who are chronically ill, older, or in need of care. Elderly people are particularly at risk because the vitamin D production of one’s own body decreases with age. Moreover, people with chronical gastrointestinal, liver, or kidney diseases are counted in the risk group because they often have a poor vitamin D utilization.

The symptoms of a vitamin D deficiency are diverse and vary from person to person. On one hand, there can be psychological symptoms such as tiredness and difficulty concentrating; on the other hand, there can be physical symptoms like bone pain, hair loss, and frequent infections. A particularly significant vitamin D deficiency can have severe consequences, such as bone problems or the development of rickets, in the long-term.

A deficiency is defined as the absence of vitamin D over a long period of time and, at the same time, the occurrence of symptoms which indicate a vitamin D deficiency. The level of vitamin D can be affected by strong seasonal fluctuations, which is why the measurement should be repeated after some time to determine if there is a long-term deficiency, as well as to get a full overview of the results.

A vitamin D excess is as damaging as a vitamin D deficiency. Usually, a vitamin D excess does not develop from endogenous production or the absorption through normal foods. However, taking excessively high doses of supplements, eating enriched foods, or taking medications can cause an acute poisoning or an insidious overdose.

Due to the high vitamin D level in the body, an overdose leads to increased calcium levels. This so-called hypercalcemia is followed by symptoms such as sickness, stomach aches, or vomiting. In serious cases, it can also cause kidney damage or cardiac arrhythmia; and in the worst cases, it may even be deadly. Taking supplements should therefore constantly be controlled and should only be taken if there is an actual deficiency.

Symptoms the Vitamin D Test is suitable for:
  • Difficulty concentrating
  • Susceptibility to infections
  • Sleep disorders
  • Fatigue
  • Muscle weakness
  • Hair loss
  • Muscle pain
  • Disturbed bone mineralization
  • Depressive moods
  • Mood swings

Any Questions?

Here are some of the most frequently asked questions regarding this test. Your question is missing? Please contact us at:

When do we speak of a vitamin D deficiency?

A deficiency is described as a lack of vitamin D in the body over a longer period of time while symptoms that indicate a vitamin D deficiency (such as rickets) occur at the same time. Since the vitamin D level is subject to strong seasonal fluctuations, it makes sense to repeat the measurement after some time to obtain a comprehensive picture of the values in order to determine a long-term deficiency.

Can you also have a vitamin D excess?

Yes! An excess of vitamin D is just as harmful as a deficiency. Vitamin D is a fat-soluble vitamin and is stored in the body. Excess vitamin D is usually not possible through the body's own production or intake through normal foods. However, by taking excessive doses of supplements, fortified foods or medications, both acute intoxication and gradual overdose can occur. The latter leads to elevated calcium levels due to the high vitamin D levels in the body. This so-called hypercalcemia can lead to nausea, abdominal pain, vomiting or, in severe cases, kidney damage or cardiac arrhythmias and, in the worst case, can be fatal. Supplements should therefore be taken under constant control and only in the event of an actual deficiency.

Is it possible to cover the vitamin D requirement through food?

It is difficult to ensure an adequate supply through food, since only a few foods contain significant amounts of vitamin D. These include, for example, fatty sea fish, some offal or mushrooms.

Who is at increased risk for deficiency?

People who rarely spend time outdoors are at increased risk of deficiency. This includes, above all, chronically ill, elderly people or people in need of care. Elderly people are also particularly at risk because their own production of vitamin D declines with age. Risk groups also include people with chronic gastrointestinal, liver or kidney diseases, as they often have poor vitamin D utilization.

I am not getting enough blood from my finger, what can I do?

Prepare the blood draw well: Hold your hand a little longer under warm water and circle your arm to stimulate blood circulation. Prick the finger on the side, not directly on top of the fingertip. The middle or ring finger of the non-dominant hand is usually best. When piercing, place your finger on a firm surface to avoid unconscious pulling back. A light squeeze and massage towards the fingertip helps stimulate blood flow.
