Vitamin D Test

29,00 Free Shipping

Do you have a vitamin D deficiency? Having enough vitamin D is important for both body and mind. Vitamin D is essential for bone health and can have a positive effect on your mood. Additionally, vitamin D is important in maintaining the immune system. However, many people living in Western Europe have insufficient levels of Vitamin D. In the winter this is even more common as there is less daily sunlight and people do not go outside as often. This is why it is wise to regularly check your vitamin D level. Homed-IQ’s Vitamin D test can be easily performed at home, with laboratory certified results in days.

Test method: Finger prick test

About the test

What is a Vitamin D Test?

This test measures the amount of vitamin D in your blood. There are two different forms of vitamin D in the blood: the active form 1,25-dihydroxy vitamin D and the inactive form 25-hydroxy vitamin D, which serves as stock for the active form. To determine whether an individual has enough vitamin D, the inactive form is usually measured.

What’s in the test kit?

This test kit contains instructions for use, lancets to collect a few drops of blood, a blood collection tube, alcohol wipes, band-aids, a protective transport bag and a return envelope to send your sample to our certified laboratory.

What do the results of this test mean?

Vitamin D Deficiency

A vitamin D level below 30 Ng/mL indicates a vitamin D deficiency. This can be caused by different factors, such as getting too little sunlight or insufficient absorption in the intestines. The following measures can be taken to treat a vitamin D deficiency:

  1. Getting more sunlight.
  2. Eating more foods that contain vitamin D. For example, oily fish (salmon, mackerel tuna)
  3. Taking dietary supplements.

Sufficient Vitamin D

If vitamin D levels are above 30 nmol/l, this means that your vitamin D level is sufficient.

Is it wise to take supplements based on this test result?

If your test result shows that you are deficient in vitamin D, we recommend that you first check whether you are receiving enough sunlight. It often helps a lot to go outside for half an hour every day between 11 am and 3 pm. Additionally, take a critical look at your diet. For example, do you eat enough oily fish? Regardless of lifestyle, it is recommended that elderly people, pregnant women, young children, individuals with a dark complexion, and those who do not go outside often take a daily Vitamin D supplement (NHS, 2021). You can get vitamin D supplements from the drugstore.

Frequently asked questions

What is the best vitamin D supplement?

There are many different Vitamin D supplements out there. We recommend asking your doctor or pharmacist for recommendations if you are unsure what type of supplement to choose.

Is this laboratory-certified test more reliable than a rapid vitamin self-test?

Yes. With Homed-IQ’s Vitamin D test you will receive a test report containing a quantitative result and an interpretation of what next steps should be taken. Most self-tests available at drugstores are less reliable as they do not involve laboratory analysis and often only provide a positive or negative result. This provides insufficient information about the precise vitamin concentration in the blood.

What foods naturally contain Vitamin D?

Most fatty fish such as tuna, salmon and mackerel, but also fish liver oil contain vitamin D. Other examples of foods that contain vitamins D2 and D3 are cheese, egg yolks and mushrooms, but in much lower doses.

What are the risks of a vitamin D deficiency?

A long-term vitamin D deficiency causes weaker bones, both in children and adults.

Can I also check the value of other vitamins or minerals?

This test only measures vitamin D levels in blood. If you would also like to test for other vitamins, we recommend that you opt for our Vitamin Deficiency Test. In addition to vitamin D, this test also measures folic acid and vitamin B12 levels in the blood.

How reliable is this vitamin D test?

The sensitivity and specificity for this blood test is almost 100%. Sensitivity is the ability of a test to correctly identify test users with a disease. Specificity is the ability of a test to correctly identify test users without the disease.

What is a normal vitamin D level?

For people under 70 years of age, the target value of vitamin D is 30 nmol/L. For people over 70 years old this is 50 nmol/L

(Gezondheidsraad, 2012).

What percentage of the population is vitamin D deficient?

It is estimated that 30-60% of the population is vitamin D deficient in Western Europe, particularly in the winter months. This is due in part to a climate that does not have much sunlight in the winter months and a lifestyle in which people are not outside for extended periods of time daily.

What causes vitamin D deficiency?

Vitamin D deficiency is most often caused by inadequate exposure to sunlight or a diet lacking Vitamin D rich foods. Vitamin D supplements can help in case of a vitamin D deficiency. It is also possible to have a vitamin D level that is too high, usually from excessive use of supplements. To learn more, read our blog “How much vitamin D is too much?“.

How much vitamin D do you need daily?

The recommended daily intake of vitamin D for most people is 10 micrograms. The safe upper limit for vitamin D has been set at 100 micrograms per day. Some individuals need more vitamin D than they can get from sunlight or food. People with a dark complexion, young children and pregnant women benefit from an additional 10 micrograms of vitamin D per day. Elderly people are recommended to receive an extra 20 micrograms per day (Voedingscentrum).

How do you know if you are deficient in vitamin D?

Vitamin D deficiency may have no noticeable symptoms, but is often indicated by symptoms of fatigue or muscle cramps. Other symptoms can also occur, such as;

  • Hypersensitive or bleeding gums
  • Pain in joints
  • Muscle pain
  • Weakened bones
