DNA test kits allow individuals to learn more about their ancestry and genetic makeup by analyzing DNA samples. These at-home testing kits make it easy for anyone to participate by requiring only a simple saliva sample that is then sent off to an accredited lab for analysis. At the lab, specific genetic markers from the sample are examined and used to provide reports on ethnicity estimates and potential relative matches.

How DNA Testing Works

DNA, or deoxyribonucleic acid, is the building block of life that is found in almost every cell within the human body. It contains the genetic instructions that make each person uniquely them. DNA testing works by examining specific locations, or markers, within a person's DNA that can reveal ancestral information. Certain genetic markers are characteristic of particular populations and geographical regions.
