Bests & Worsts Reviews from Amazon

This DNA test from 23andMe gives you a huge amount of raw data. If you're looking for medical information (not just ancestry), you are getting your money's worth. However, due to FDA regulations, they aren't allowed to interpret it for you beyond some very basic (and frankly unhelpful) reports. This is true for all DNA testing companies when it comes to medical information. The good news is that you can upload your 23andMe data to other websites and receive detailed reports. Promethease.com gives you detailed reporting for just $5 - everything from vulnerabilities to diseases, to genes associated with personality traits. Another commenter mentioned the MTHFR mutations, which are associated with many chronic illnesses. Geneticgenie.org will run your 23andMe results specifically related to these genes, and the report is free. And if you can afford it, the best way to interpret your results is to make an appointment with a genetic counselor, who you can find through NSGC.org. So, you're paying for the data with this test, and it's just a few extra steps to understand the data.
