Independent Laboratory
Your test is analyzed by an independent and GMP-certified laboratory. The fact that Vitas is GMP-certified means that they follow good manufacturing practices. They are a contract laboratory for chemical analysis with 25 years of experience, providing high-quality chromatographic analysis based on cutting-edge knowledge and technology. Included with the blood test is a Vitamin D test ID that only you can see. Neither the lab, nor Zinzino knows who submitted the test. At zinzinotest.com your results will be displayed when you enter your vitamin D test ID. If you have completed the questionnaire, you will have access to the complete analysis. If you have not completed the questionnaire, you will see your vitamin D status in nmol/L only.
Your answers matter
The best option is to answer the questions at the same time as you take the blood test. You can then access all your results very easily once the analysis is done.
Any doubts? Don’t worry, you can see vitamin D status without answering the questions – you can see for yourself there is no change in your results even after the questions have been answered.
By answering these quick questions, you will have access to all the analytical result for your vitamin D status, as well as various information about your risk factors but even more importantly, you will contribute to making it possible for scientists to use the database in future science projects.
Certified Test Kit
The Zinzino Dried Blood Spot Test is certified to comply with the European regulation 98/79/EG and is certified according to ISO 13485 on in vitro diagnostic (IVD) medical devices. This means the test and all its components are in compliance with applicable laws and regulations, and so the Kit has the CE mark on it.
