Yes. There are a few actions you can take to become (almost) anonymous in a DNA database.
1. Create an email address which you solely use for registering and managing the DNA results
2. Order a DNA test and have it sent to a friend or relative at another address
3. When registering the DNA test, use an alias. Some companies don't want you to use initials, so a "real" name would be better.
