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).

More on: our lab.

A CLIA-certified and CAP-accredited 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.

The analysis we perform is called genotyping. Our genotyping looks at hundreds of thousands of specific locations on your DNA. These locations are known to vary between individuals, and some are associated with certain conditions, traits, or ancestry.

We use leading technology to genotype your DNA—a custom Illumina HumanOmniExpress-24 format chip.

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
Principal 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."

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.

A variant is a difference in the DNA sequence between two individuals. Variants can cause specific diseases, contribute to diseases or traits (along with the environment), or have no effect. Variants can be passed down from parent to child.

The analysis we perform is called genotyping. Genotyping looks at specific locations in your DNA and identifies variations. These variations make you unique.

In choosing these specific locations, we focus on the variations that are known to be associated with important health conditions, ancestry and traits. Genotyping is a great way to start understanding how your genetics can impact your life.

23andMe refers to the 23 pairs of chromosomes in your DNA.

*The 23andMe PGS test uses qualitative genotyping to detect select clinically relevant variants in the genomic DNA of adults from saliva for the purpose of reporting and interpreting genetic health risks and reporting carrier status. It is not intended to diagnose any disease. Your ethnicity may affect the relevance of each report and how your genetic health risk results are interpreted. 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. The test is 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, how much of a medication you should take, or determine any treatment. 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, the health of your fetus, or your newborn child's risk of developing a particular disease later in life. For certain conditions, we provide a single report that includes information on both carrier status and genetic health risk.
