What does the vitamin D test measure?

25-OH-vitamin D

25-OH-vitamin D is the primary circulating form of vitamin D and is used to assess the body's vitamin D status. Vitamin D plays a role in areas such as bone health, calcium metabolism, and muscle function.

Common symptoms and when the test may be relevant

A test may be relevant in cases of low sun exposure, limited vitamin D intake, previously low levels, or symptoms warranting a broader medical assessment. Levels often vary throughout the year and, in Sweden, are typically lower after the winter season.

• fatigue
• muscle weakness
• diffuse aches
• skeletal effects in cases of severe or prolonged deficiency

Many people with low levels show no clear symptoms, and the issues listed above can have various other causes.

Who is this test for?

• Those with limited sun exposure.
• Those who want to monitor a previous vitamin D level.
• Those who take vitamin D supplements and want a reading to help assess their status.
• Those who prefer home testing.

How the home lab test works

1. Order the test. You receive a complete sample collection kit.
2. Read the instructions. Prepare the materials and warm your hands to improve blood flow.
3. Collect the sample at home. Prick your fingertip and collect liquid capillary blood in the test tube according to the instructions.
4. Send the sample. Label, seal, and pack the sample, then send it to the laboratory using the return materials provided.
5. Laboratory analysis. The sample is analyzed using a quality-assured laboratory method.
6. View the result digitally. The laboratory result is displayed in your personal health portal.

Before sample collection

Follow the instructions in the sample collection kit. Vitamin D supplements can affect the result. Do not alter prescribed treatment without first consulting a healthcare professional.

Laboratory and quality

The sample is analyzed at a medical laboratory accredited according to ISO 15189. The laboratory's quality assurance also complies with Rili-BÄK, the German medical association's guideline for quality assurance in laboratory medical testing.

• Sample material: liquid capillary blood
• Collection site: at home
• Result: digital laboratory report
• Turnaround time: transport time and the scope of the analysis affect the total time

Results and reference values

You will receive a quantitative result—including the laboratory's unit of measurement and the applicable reference ranges—in your personal health portal. Reference ranges may vary between laboratories and can sometimes be influenced by individual factors. An abnormal result is not a diagnosis in itself.

Important information about the results

The test provides information on the analyzed markers but does not provide a diagnosis and does not replace medical assessment or treatment. Contact a healthcare professional in the event of abnormal results, distinct or persistent symptoms, or concerns.

Do Vitamin D levels vary throughout the year?

Yes. Sunlight contributes to the body's production of vitamin D, meaning levels can vary between seasons.

Can supplements affect the level?

Yes. Vitamin D supplements can affect the measured level and should be taken into account when interpreting the result.

Does the test provide a diagnosis?

No. The result shows your measured level and needs to be assessed within its medical context.
