Of course, most DNA used by law enforcement in the U.S. does not come from direct-to-consumer DNA tests. The federal government and many states collect DNA samples from suspects of violent crimes after arrest or due to probable cause. These samples are added to the Combined DNA Index System, or CODIS, which is a national database for forensic information.
If the company responsible for running your test is sold, whatever you signed loses significance due to the privacy policies of the company. Despite most of these privacy policies stating they will notify you of any changes, you would have to keep in constant contact with the company to ensure you were actually aware of these changes. The people willing to do this would be far and few between. Unfortunately, even if your name is not located within the database, this does not mean other databases cannot be used to determine your identity. In one specific case, a woman had a DNA test run. She found out she had a half-sibling. Although she was very excited about this news, this type of information would devastate numerous individuals.
If you want to keep things really simple then we recommend 23andMe as it offers the best all-round DNA testing kit. It offers a mix of everything including family matching, ancestry percentages and optional heath insights. If you’re more interested in your genealogy then the AncestryDNA kit provides more detail along a gene pool and family tree. The National Geographic Geno 2.0 DNA kit is the best kit for connecting your genes to history going back up to 100,000 years.

DNA tests give you an educated estimate of your ethnic makeup and help inform genealogical research by verifying existing family trees and informing future avenues of investigation. Additionally, there's a possibility you'll find living DNA matches - distant cousins and other relations - who could share their family history with you to build a bigger picture of your family tree.


If you opt in to DNA Relatives, you will be able to send and receive invitations to connect with other customers who share DNA with you. You can choose whether to respond to these invitations or not, and your DNA relatives have the same choice. We cannot guarantee that they will respond to your sharing invitations or messages. Regardless of whether you both agree to share, you will be able to see their birthplace, locations of their ancestors and surnames, if they have chosen to add this information to their profile. If you both accept sharing invitations, you will be able to see ancestry reports and overlapping chromosome segments.
We provide sample collection kits for all our tests. Paternity testing, relationship tests and most of our other tests entail the easiest and most painless method of sample collection using oral swab samples. Visit our collection guide for information about how to collect your own samples from home using our DNA test kit. Thanks to state-of-the-art genetic identification systems we are able to perform testing with many other samples such as hair, garments and toothbrushes. The discreet DNA samples section has more information on the types of totally non-invasive samples that can be tested.
It’s easy to do these tests; it’s usually just a case of collecting your own samples at home, filling in short, basic questionnaires, posting the packages, and then logging on to interactive websites for confidential results (all the kits I tested used outside laboratories). With an array of price ranges and options, from one-off DNA-blitzes to targeting specific health areas, to fitness/wellness tracking, it’s no surprise that these kits are proving to be very big business and the field is primed to get even bigger, with a global market estimated to be worth around £7.7bn by 2022.
