One warning that has been circulation for a number of years: “Don’t open the closet because it might contain a skeleton” appears to be true in a recent case. If you are thinking about having your DNA analyzed, you might pause to consider a recent case in England:

A woman has been left heartbroken after a DNA test revealed a harsh truth about her family - shattering her bond with them forever.

Speaking on her behalf, her auntie explained how she ordered a 23andMe test because she was curious about her genealogy and family heritage.

But when the results came in, her entire world started crashing down around her as she came to realise her 'life was a lie'. She said on Reddit: "I know that everyone is curious about their genealogy and it seems a harmless (and could be useful in the case of genetic health issues) test – but it's also important to remember that DNA testing can unearth family secrets that it serves no one to unearth.

"I saw this in my family when a niece did a 23andMe and found out her father was not her bio-father. The mom was shocked although she had been having an affair, she had made a conscious decision to end it because she wanted a stable family for her child. She had no idea that she was pregnant with the other person's child. She was deeply in love with the man but refused to break up the marriage over it."

Yes, it could happen to you.
