Genetic testing of any form sometimes uncovers things that people are not ready for, like the presence of a genetic disease, or the discovery that your karyotype is not what you thought it was, or the finding that the man you think is your father actually isn’t. That’s one reason why genetic counseling is recommended in conjunction with testing; people argue that these kinds of tests shouldn’t be used lightly or played for cheap stunts like they are on “Maury,” where people get paternity test results live on air for shock value.
