The public may be misled about the real benefit of these tests and it is often not aware of the limitations of the test. Without consulting a geneticist is also difficult to interpret correctly the test result. Finally, it is found that those who undergo the tests rarely obtain beneficial results, even changing their lifestyle or reducing the state of anxiety.
