The Science Behind Canna DNA Testing
"How can we trust the test's accuracy?"
70 different peer-reviewed publications were used as a foundation for the guidance provided in the report. A very conservative estimate of 2 months per publication would yield a total of 112,000 hours of research (40 hours in a day * 5 work days a week * 4 weeks per month * 2 months * 70 publications) behind the test.
All the interpretations and conclusions are based on peer-reviewed scientific studies. This link is an excellent starting point for explaining and understanding pharmacogenomics, which is the main basis of this test, at least the pharmacogenomics (metabolism) traits.
This was published in 2023 in Current Issues in Molecular Biology which has a very decent impact factor of 3.
