Vitamin D test

Vitamin D is an essential nutrient that supports your body in several ways. It helps with the absorption of calcium and phosphorus, which is important for strong bones and teeth. Vitamin D also plays a role in normal muscle function and contributes to a healthy immune system, your body’s natural defence against illnesses and infections.

There are also indications that vitamin D may influence your mood and brain health. A deficiency can sometimes cause symptoms such as fatigue or low mood. Vitamin D deficiency is relatively common in Western Europe, particularly during autumn and winter or among people who spend little time outdoors.

Would you like to know whether your vitamin D level is adequate? With our laboratory test, you can check this quickly and easily from home, without having to visit a doctor or clinic.

About the test

Vitamin D test explained

Taking the Vitamin D test is quick and easy. Warm your hands, for example with warm water. Clean the puncture site with the supplied wipe and use the included lancet to prick your finger. Let the blood drip into the tube one drop at a time and take your time. Then close the tube securely and send it back easily and free of charge using the enclosed return envelope.

Results

Test results provide a snapshot in time and can be influenced by factors such as diet, lifestyle, medication and the time of sample collection. Abnormal values do not automatically mean that you have a medical condition.

About vitamin D

How do you get vitamin D?

Your body can obtain vitamin D in several ways. The most important source is sunlight. Although vitamin D itself is not present in sunlight, your skin produces it when exposed to sunlight. The ultraviolet (UV) rays from the sun cause your body to produce vitamin D.

You can also get vitamin D from food. Fatty fish (such as salmon, mackerel and herring), eggs, mushrooms and fortified products such as some breakfast cereals, dairy products or plant-based milk and orange juice can contribute to your intake.

For people who get little sunlight, for example during winter or due to an indoor lifestyle, it can be difficult to get enough vitamin D from food alone. In such cases, a deficiency can develop. Regular monitoring, for example through a test, can help identify deficiencies early. This allows you to adjust your sun exposure, improve your diet or take a supplement.

Why do a vitamin D test yourself?

A vitamin D self-test has several advantages. You do not need to make an appointment with a doctor and can take the test whenever it suits you. The test is easy to perform at home and the results are often available quickly.

At Labtest.nl, all vitamin D samples are analysed in a certified laboratory.

Benefits at a glance:

  • Your sample is analysed by a certified laboratory
  • The test is easy to perform yourself
  • You quickly gain insight into your vitamin D level

Why consider a vitamin D test?

It is always a good idea to keep an eye on your vitamin D level. During the winter months, many people get less sunlight and therefore produce less vitamin D. By testing regularly, you can see how your levels vary throughout the year. This can help you determine whether you may need additional vitamin D.

If you experience symptoms such as fatigue, muscle weakness, low mood or frequent illness, it may also be useful to test your vitamin D level. This can help you determine whether you have a deficiency or whether something else may be causing your symptoms.

Biomarker summary

Vitamin D: Essential for good health

Frequently Asked Questions Everything about Vitamin D test

A vitamin D test is not necessary for everyone, but it can be valuable if you have symptoms or are at risk of a deficiency. This may include fatigue, muscle pain, or a reduced immune response.

Such a test provides insight into your vitamin D level. Sometimes symptoms may appear to be caused by a deficiency, while the actual cause lies elsewhere. With a reliable test, you can determine whether you truly have a deficiency or, on the contrary, an excess, allowing you to take targeted action. If you are unsure, it is always advisable to discuss your test results with a doctor.

There are many vitamin D supplements available. This can make it difficult to determine which supplement is most suitable for your situation. It is important to consider the correct dosage and form of vitamin D. If you are unsure, ask your doctor or pharmacist for advice.

Yes, the laboratory test from Labtest.nl is much more accurate than most rapid tests available at pharmacies. With Labtest.nl, your blood sample is professionally analysed in a certified laboratory. You receive a detailed report with your exact vitamin D level, allowing you to take targeted action if needed.

Many home tests available in stores only provide a positive or negative result, without showing exact values. This provides less insight into how severe a possible deficiency may be. If you want to know exactly where you stand, a laboratory test is the best choice.

ViVitamin D naturally occurs in a limited number of foods. The richest sources are:

  • Oily fish such as salmon, mackerel, herring, and tuna
  • Fish liver oil (such as cod liver oil)
  • Egg yolks
  • Cheese
  • Certain mushrooms (especially when exposed to sunlight)

The amounts found in eggs, cheese, and mushrooms are lower than in fish. Therefore, it can sometimes be difficult to get enough vitamin D from food alone, especially during winter or if you get little sunlight. In such cases, a supplement may help.

A long-term vitamin D deficiency can have negative effects on your health. Some important risks include:

  • Brittle bones or bone loss (osteoporosis), which increases the risk of fractures
  • Delayed growth and skeletal problems in children (such as rickets)
  • Muscle weakness and muscle pain, which can increase the risk of falls in older adults
  • Reduced immunity, making you more susceptible to illness
  • A possible role in low mood or depressive symptoms

A deficiency is not always immediately noticeable, but it can cause damage in the long term. If you are unsure or have persistent symptoms, it is advisable to have your vitamin D levels tested and discuss the results with your doctor.

This test from Labtest.nl only measures your vitamin D level in your blood. If you would also like to check your vitamin B12 and folic acid levels, you can choose our vitamin deficiency test. This test measures your vitamin D, B12, and folic acid levels all at once. This gives you a broader insight into your nutritional status.

In the Netherlands, a large part of the population has a vitamin D deficiency, especially during winter. Research shows that:

  • During the winter months, around 59% have vitamin D levels that are too low
  • During the summer months, this is still around 35%

According to some experts, the actual percentage may be even higher, with up to 90% of people potentially having insufficient vitamin D levels.

Despite this, a deficiency is often not recognised or tested. Only a small percentage of doctors (around 5%) routinely perform vitamin D testing. As a result, symptoms may sometimes go unnoticed, even though a deficiency is relatively easy to treat. If you have symptoms or are unsure, it is advisable to have your vitamin D levels checked.

The vitamin B12 test we use is highly accurate and reliable. The test has a sensitivity and specificity that are close to 100%.

  • Sensitivity means that the test is very good at detecting a vitamin B12 deficiency when it is present.
  • Specificity means that the test can reliably confirm that there is no deficiency when this is actually the case.

You can therefore rely on a trustworthy result, provided that the test is performed and analysed correctly. At Labtest.nl, this is done in an ISO 15189-certified laboratory.

A vitamin D deficiency is quite common, especially during winter. Research shows that in the Netherlands, around 59% of people have insufficient vitamin D levels in winter. In summer, this is still around 35%. The main causes are limited sunlight exposure, a diet low in oily fish, and not using supplements when there is an increased need. A supplement can help, but be aware: too much vitamin D (often due to excessive use of supplements) can also be harmful.

For most people, the recommended daily amount is 10 micrograms of vitamin D. Some groups need more, for example:

  • People over the age of 70: 20 micrograms per day
  • People with darker skin, young children, and pregnant women: an additional 10 micrograms per day

The maximum safe amount is 100 micrograms per day. If you spend little time outdoors or get little vitamin D from your diet, a supplement may help. If in doubt, always consult your doctor.

A vitamin D deficiency is not always immediately noticeable, but it can cause symptoms. Common signs include:

  • Persistent fatigue
  • Muscle cramps or muscle pain
  • Joint complaints
  • Painful or sensitive teeth and gums
  • Weaker bones or more frequent bone fractures

Are you unsure whether you are getting enough vitamin D? You can have this tested or discuss it with your doctor. A deficiency is especially common during winter or when you get little sunlight.
