How to find a good DNA testing company in South Wales


Finding a reputable & trustworthy testing lab can be difficult. With so many companies out there offering so many products, it's hard knowing where to start.

If you are based in Cardiff or the surrounding South Wales area, we recommend checking out this company or this one.

Always be sure to use an accredited DNA testing lab - specifically the ISO/IEC 17025 standard, which applies to testing and calibration laboratories.

According to the ISO website:

"ISO/IEC 17025 enables laboratories to demonstrate that they operate competently and generate valid results, thereby promoting confidence in their work both nationally and around the world. It also helps facilitate cooperation between laboratories and other bodies by generating wider acceptance of results between countries. Test reports and certificates can be accepted from one country to another without the need for further testing, which, in turn, improves international trade."
