About your ethnic composition

In order to estimate your ethnic composition, we use a reference panel comprising of a range of ethnic groups from Asia and around the world.

Your DNA results have been matched against the reference panel in order to estimate your ethnic composition. All ethnicities might not fully be covered in our reference panel and in such a case, the ethnic group would not be identified in the results provided. Our reference panel will be continuously enriched to ensure most ethnicities are included.

In addition, your ethnic estimate will feature a range of possible percentages by making multiple comparisons of your DNA against our reference panel. While the most consistent and related results will be displayed, the possible range are estimates. This is a very common practice within the industry.

As more users undertake our genetic tests, our panel reference, algorithms and analysis will be enhanced to provide more refined information as well as reflect latest developments, technology updates and new scientific discoveries. We are transparent about our science and look to keep enhancing our algorithms for further accuracy.

Your DNA does not change throughout your lifetime, however based on constant research and development, GeneLife keeps refining and improving its science. This may result in getting the information and content displayed to be refreshed or changed any time, including your results.
