Why genetic testing matters for Alzheimer’s awareness.

Late-Onset Alzheimer’s Disease. You do not have the ε4 variant we tested.
  • Alzheimer’s begins 10-20 years or more before memory loss develops.5 More info Genetic testing can help you identify hidden risks.
  • Strides have been made for Alzheimer’s and its risk factors, many of which are preventable if acted on early.6 More info

Make an informed choice.

You can choose to opt in to our FDA Authorized late-onset Alzheimer's Genetic Health Risk report. We provide you with information you need to make the right choice for you.

For those at risk, we provide recommendations and emerging science on how you can work to lower Alzheimer's disease risk.

Frequently Asked Questions

What health conditions does 23andMe test for?
23andMe offers a variety of health reports like Type 2 Diabetes (Powered by 23andMe Research), Celiac Disease Genetic Health Risk Report*Learn about Considerations and Limitations for Health Predispositions Reports, Carrier Status Reports and Genetic Health Risks, BRCA1/BRCA2 (Selected Variants) Genetic Health Risk Report*Learn about Considerations and Limitations for Health Predispositions Reports, Carrier Status Reports and Genetic Health Risks and many more. to see a list of all the reports offered.
What will 23andMe's Health + Ancestry Service tell me?
Your 23andMe Health reports can tell you how your DNA can impact your chances of developing certain conditions. Wellness reports can help you discover what your DNA has to say about lifestyle factors like diet, exercise, and sleep. And if you're thinking of starting a family, our Carrier Status reports can tell you if you're a carrier for genetic variants linked to certain inherited health conditions.*Learn about Considerations and Limitations for Health Predispositions Reports, Carrier Status Reports and Genetic Health Risks
Is 23andMe diagnostic?
No, 23andMe reports do not diagnose any health conditions or provide medical advice. While having a particular genetic variant can be linked to a higher risk for a condition, it does not necessarily mean you will develop the condition. It is also important to remember that these reports do not cover all possible genetic variants that could influence risk. Other non-genetic factors, such as environment and lifestyle, can also influence risk for these conditions. We recommend that you consult with a healthcare professional if a condition runs in your family, you think you might have the condition or you have questions about any genetic or non-genetic risk factors you may have.

*The 23andMe PGS test includes health predisposition and carrier status reports. Health predisposition reports include both reports that meet FDA requirements for genetic health risks and PRS reports which are based on a genetic model that includes data and insights from 23andMe consented research participants, and have not been reviewed by the FDA. The 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. Each PRS report describes if a person has a certain likelihood of developing a condition, but does not describe a person’s overall likelihood. 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. Warnings & Limitations: The 23andMe PGS Genetic Health Risk Report for BRCA1/BRCA2 (Selected Variants) is indicated for reporting of 44 variants in the BRCA1 and BRCA2 genes. The report describes if a person's genetic result is associated with an increased risk of developing breast cancer and ovarian cancer and may be associated with an increased risk for prostate cancer, pancreatic cancer, and potentially other cancers. The variants included in this report do not represent the majority of the BRCA1/BRCA2 variants in people of most ethnicities. The MUTYH-Associated Polyposis Genetic Health Risk Report is indicated for reporting the Y179C and G396D variants in the MUTYH gene and an increased risk for colorectal cancer. The two variants included in this report are most common in people of Northern European descent. The Hereditary Prostate Cancer (HOXB13-Related) Genetic Health Risk report is indicated for reporting the G84E variant in the HOXB13 gene. The report describes if a person has the G84E variant and if a male is at increased risk for prostate cancer. The variant included in this report is most common in people of European descent, especially in people of Northern European descent. These reports do not include variants in other genes linked to hereditary cancers and the absence of variants included in this report does not rule out the presence of other genetic variants that may impact cancer risk. These reports are for over-the-counter use by adults, and provide genetic information to inform discussions with a healthcare professional. The PGS test is not a substitute for visits to a healthcare professional for recommended screenings or appropriate follow-up. Results should be confirmed by an independent genetic test prescribed by your own healthcare provider before taking any medical action.
