23andMe is a DNA analysis service providing information and tools for individuals to learn about and explore their DNA, by getting to know their ancestry or which diseases they are prone to have. Fans of self-testing says it’s interesting to find out about your ancestry, useful to know if you’re at increased risk of certain conditions and reassuring to know if you’re not. If the test points to risk, you can take preventive action, for example by losing weight if you’re prone to diabetes. 23andme are changing the way the world does research by allowing everyone to participate in research - online. At home. In the office. Day or night.
