Whether you're looking to discover more about your genealogy or gain an insight into your family's medical history, DNA testing kits continue to grow in popularity.
According to a new study by the respected Pew Research Center, approximately one-in-seven American adults have used a mail-in DNA testing service – with many admitting they were surprised by what they learnt.
The vast majority of respondents (87%) were using DNA testing kits to trace their family origins, but a significant proportion (36%) were also interested in their family's medical history.

Who do you think you are?!
The survey reveals that while most people's results roughly lined up with their expectations, a large number of respondents learnt something new through a mail-in DNA test kit.
Specifically, some 38% of participants were surprised by the country or continent their ancestors came from, while over a quarter (27%) said the results of their test revealed a new family connection or relative.
A further 26% of those surveyed said they were intrigued by the medical information they received. According to this part of the study, women were more likely to be surprised by their family's health history than men (33% vs 19%).
Beware the scam artists
The rise of mail-in DNA test kits isn't without its dangers, however.
For many people, the biggest shock from taking a DNA test is likely to be learning about a new cousin that lives across the country – but there has also been a more worrying wise in Medicare scams related to DNA testing recently.
As a result, those interested in learning more about their genetics should either consult their primary care provider for health-related DNA testing, or order a kit from a reputable brand like 23andMe or AncestryDNA.
