DNA tests are one of the hottest gifts of the season, but you may want to think twice about sticking one under the tree this year.
Some psychologists are warning people that they may be stirring up some family drama with those tests.
"We might find out information that we're not prepared for," clinical psychologist Jephtha Tausig-Edwards, Ph.D, said.
Because on top of finding out cool stuff like your ethnic background, you could find out something less cool.
Like you have siblings you never knew about ... or your parents aren't really your parents.
"Everyone is looking for the idea of fantastic news. What people are less prepared for are long lost relatives or family secrets that may be more disturbing and upsetting," Tausig-Edwards said.
There's actually an online support group of more than a thousand people who have discovered shocking things about their parents as a result of these DNA tests.
