Shine a light on your health
Zinzino’s VitaminD Test is an easy self-test for analyzing the vitamin D levels in capillary blood obtained from a fingertip using a Dried Blood Spot (DBS) technique. A DBS is scientifically proven to be as accurate as a venous blood sample when vitamin D status is to be analyzed. All it requires is 1 to 2 drops of blood from the fingertip on a Whatman® filter paper and it takes less than a minute to complete. VITAS Analytical Services in Norway will analyze your current vitamin D status and the result is anonymous. The status can vary throughout the year depending on sun exposure, diet where you live, and food supplementation. Therefore the recommended test interval is 120 days. Using your personal test ID you will get in-depth personalized recommendations based on your vitamin D status in order to optimize it.
What we measure
There are different methods to assess stores of vitamin D in your body and we use best practice to ensure our accuracy of analysis is superior. A 25-hydroxyvitamin D test is the best way to monitor vitamin D levels as it measures the 25(OH)D, also called calcidiol, in your blood.
The test reflects all three sources of vitamin D; from food, supplements and skin synthesis, and determines if your vitamin D levels are optimal, too high or too low.
The normal range of vitamin D is measured as nanograms per milliliter (ng/mL) or nanomoles per liter (nmol/L). Nmol/L is the most common way of showing the vitamin D status. However, in the US, and a handful of other countries, the same levels are measured using ng/mL. Therefore, when the test results are presented, it is possible to select which measurement unit to be shown.
How does it work?
Start by simply pricking your finger and putting 1–2 drops of blood on a filter paper.
Register your test by entering your test ID and filling out the form. All data is anonymous.

Vitamin D uptake from sun exposure varies in many parts of the world throughout the year, and restoring your status generally takes 3–4 months of consuming vitamin D supplements, depending on the dose and your individual status. We recommend taking a new test every 4 months to track your progress and ensure you reach and maintain your optimal vitamin D status.
