Shine a light on your health
The VitaminD Test from Zinzino is a simple self-test that, after taking capillary blood from a finger, allows for the analysis of vitamin D levels using the Dried Blood Spot (DBS) technique. If our goal is to analyse vitamin D levels, it is scientifically proven that the DBS technique is just as accurate as taking a venous blood sample. Only 1 to 2 drops of blood from the fingertip placed on Whatman® filter paper are needed, and the procedure takes less than a minute. VITAS Analytical Services in Norway will analyse your current vitamin D level and the result is anonymous. The level may vary throughout the year depending on sun exposure, diet, where you live, and supplements. Therefore, the recommended interval between tests is 120 days. Your personal test ID will give you detailed personal recommendations based on your vitamin D level.

How does it work?

1. Take the test
Simply start by pricking your finger and collecting 1–2 drops of blood on the filter paper.

2. Activate your test
Register your test by entering your Test ID and filling out the form. All data is anonymous.

3. Embark on the journey
Take advantage of a clear starting point for your journey to normal immune system function. Gently adjust and maintain optimal vitamin D levels throughout the year.

4. Wait for analysis VITAS Analytical Services has more than 25 years of experience with cutting-edge knowledge and technology, ensuring that your sample is analysed independently and your personal data is protected.

5. Get results Your results are available within 10-20 days and presented in our clear graphical representation.

6. Re-test your levels Vitamin D intake from sunlight fluctuates in many parts of the world during the year, and restoring your condition usually takes 3–4 months associated with taking vitamin D supplements, depending on the dosage and your personal condition. We recommend that you take a new test every 4 months to monitor your progress and make sure you have reached and maintained optimal vitamin D levels.

What do we measure
There are various methods for assessing the vitamin D status in your body. We use a proven procedure to ensure that our analysis is more accurate. The 25-hydroxyvitamin D test is the best way to determine vitamin D levels because it measures 25(OH)D, also called calcifediol, in your blood. The test takes into account all three sources of vitamin D - food, supplements and skin synthesis. Then it determines whether your vitamin D level is optimal, too high, or too low. Normal amounts of vitamin D are measured in nanograms per millilitre (ng/ml) or nanomoles per litre (nmol/l). Nmol/l is the most common way to report vitamin D status. However, in the USA and some other countries, the same levels are measured using ng/mL. Therefore, when presenting the test results, you have the option to choose in which unit of measurement the result should be displayed.

Performing the test

1. The Zinzino Test is an approved in vitro diagnostic product for personal home blood sampling.
- First, wash your hands with soap, rinse them thoroughly with warm water and dry them.

2. Remove the sample card from the paper envelope. Keep the envelope for later use. Detach the part of the sample card marked KEEP and photograph the test identification number. You can only see your test results if you have the anonymous test identification number. Place the card on the table with the side with two circles facing up.

3. Stimulate blood flow by circling your entire arm or shaking your hands downwards for 20 seconds.

4. Remove the single-use lancet. Remove the transparent safety cap and the lancet is ready for use. Clean the tip of your finger (middle finger recommended) with an alcohol swab. Place the lancet against the lower part of the fingertip, facing the collection sheet on the table. Press the top of the lancet towards your finger until you hear a click. The lancet will automatically make a small prick in your finger.

5. Do not touch the filter paper with your fingers.

6. Gradually drip blood into each circle until they are filled. Gently squeeze your finger and wait for a drop of blood to drip into the circle. If one drop of blood does not fill the circle, immediately drip another drop from your finger into it. Leave the sample card in a horizontal position at room temperature for at least 10 minutes to allow the samples to dry thoroughly.

7. Place the sample card back into the paper envelope. Then place the paper envelope into the metallic bag and seal everything. IMPORTANT: Do not remove the desiccant bag from the metallic bag.

8. Place the sealed metallic bag into the large envelope with the laboratory address. NOTE! Before placing the envelope in the mailbox, you must affix the correct number of postage stamps to the envelope. Register your test code at www.zinzinotest.com. You will also be able to view your test results on this website later. Your results will be available in 10–20 days. IMPORTANT: Keep the part of the card marked KEEP. You can only see your test results if you have the anonymous test identification number.
