Our lab. CLIA-certified.

Your DNA analysis is performed in US laboratories that are certified to meet CLIA standards—the Clinical Laboratory Improvement Amendments of 1988.

A CLIA-certified lab must meet certain quality standards, including qualifications for individuals who perform the test and other standards that ensure the accuracy and reliability of results.

We use leading technology to genotype your DNA—a custom version of the lllumina Global Screening Array.

See stories that inspire us.

23andMe was founded in 2006 to help people access, understand and benefit from the human genome.

We have more than five million genotyped customers around the world.

Due to applicable regulations, 23andMe only offers an Ancestry + Traits Personal Genetic Service in international markets and health reports are not available. The service is in English only. It requires submitting a saliva sample using our saliva collection kit that you send to the lab for analysis.

Our Ancestry + Traits Service helps you understand who you are, where your DNA comes from and your family story. We analyze, compile and distill your DNA information into reports on your Ancestry Composition, Ancestry Detail Reports, Traits, Haplogroups, and Neanderthal Ancestry. We also provide a DNA Relatives tool to enable you to connect with relatives who share similar DNA, and an automatic Family Tree builder.

Our rigorous quality standards include:

  • All saliva samples are processed in CLIA-certified and CAP-accredited labs
  • Genotyping is a well-established and reliable platform for analyzing DNA
  • Our team of scientists and medical experts uses a robust process to develop reports to ensure validity
