Vitamin K2+D3 Test

– Vitamin K2 Test now also includes Vitamin D3 results!

With the help of a simple self-administered device, you can quickly receive your serum-concentration of vitamin K2 (MK7) and vitamin D3 level (25-OHvitaminD3). The vitamin K2 “concentration-number” in your blood gives you an indication of your relative risk to develop cardiovascular diseases and/or weak bones. In turn, 25-OHvitaminD3 is a metabolite of vitamin D3, which is considered the best indicator of vitamin D status in the body.

The blood sample collected on the filter paper is extracted and analysed according to international standards for vitamin K2 and D3 testing by Vitas AS Laboratory in Oslo, Norway. Your results can be securely accessed on after 15 – 20 business days.

Important to remember

When you receive your Vitamin K2+D3 Test, there are a few things you need to be aware of. Carefully follow the user manual in your Test Kit on how to perform the blood test.

The blood sample collection card contains an ID number. In our new Vitamin K2+D3 Test, the ID number is already placed on the blood sample card – both on the part that you tear off and keep, and at the part, you send to the laboratory. Your test is, therefore, completely confidential. It is crucial to retain the part with your ID number since you will need this number later to check your result on
