How your DNA becomes a report.

Human DNA is about 99.5% identical from person to person. However, there are small differences that make each person unique. These differences are called variants.

Your DNA was passed down from your parents—and their parents and so on. Variants can be linked to certain health conditions, traits and ancestry groups.

Your saliva contains DNA from cells in your mouth. We send you a saliva collection kit and instructions for providing your sample.

Our CLIA-certified lab extracts DNA from cells in your saliva sample. Then the lab processes the DNA on a genotyping chip that reads hundreds of thousands of variants in your genome.

Your genetic data is analyzed, and we generate your personalized reports based on well-established scientific and medical research.

Why genetics is only part of the story.

When it comes to your health and traits, DNA is only part of the story. Other variables come into play, including non-genetic factors, such as your environment and lifestyle.

Our process at work.

To ensure quality, your DNA analysis is performed in US laboratories that are certified by CLIA (Clinical Laboratory Improvement Amendments of 1988) and accredited by the College of American Pathologists (CAP).

Here are some of the people behind the science at 23andMe.

"The high quality genetic research we do at 23andMe is possible because of our customers who share their data and want to make a difference."

David H., PhD
Principle Scientist

"I am passionate about genetics because I am fascinated by how humans are different from one another, and what DNA tells us about those differences."

Joanna M., PhD
Senior Director of Research

"Be curious. Ask questions. The more we understand about our fascinatingly complex selves, the better we can take care of each other and the beautiful world we live in."

Joyce T., PhD
VP of Research

Hi. Still have questions about science?

Here are just a few of the things people frequently ask about 23andMe.
If you don't see your question here, get in touch with us.



*The 23andMe PGS test uses qualitative genotyping to detect clinically relevant variants in the genomic DNA of adults from saliva collected using an FDA-cleared collection device (Oragene·DX model OGD-500.001) for the purpose of reporting and interpreting genetic health risks and reporting carrier status. It is not intended to diagnose any disease. The relevance of each report may vary based on ethnicity. Each genetic health risk report describes if a person has variants associated with a higher risk of developing a disease, but does not describe a person's overall risk of developing the disease. These reports are not intended to tell you anything about your current state of health, or to be used to make medical decisions, including whether or not you should take a medication or how much of a medication you should take. Our carrier status reports can be used to determine carrier status, but cannot determine if you have two copies of any genetic variant. These carrier reports are not intended to tell you anything about your risk for developing a disease in the future or anything about the health of your fetus, or your newborn child's risk of developing a particular disease later in life. For Gaucher Disease Type 1, we provide a single report that includes information on both carrier status and genetic health risk. The Parkinson's Disease genetic health risk report (i) is indicated for reporting of the G2019S variant in the LRRK2 gene, and the N370S variant in the GBA gene, (ii) describes if a person has variants associated with an increased risk of developing Parkinson's disease, and (iii) is most relevant for people of European, Ashkenazi Jewish, and North African Berber descent.
