Rate This:Determining Your Risk of Alzheimer's with a Home Testing Kit
Do you have a genetic predisposition to late-onset Alzheimer's? Now you can find out using a home genetic testing kit made by California-based 23andMe Inc. The US Food and Drug Administration just approved the company's Personal Genome Service, which allows people to send saliva samples to be professionally tested for genetic predispositions for Alzheimer's and nine other illnesses. Keep in mind, having a genetic predisposition doesn't mean you're guaranteed to get sick -- these diseases are rare even among people with dispositions -- but home genetics testing can spark important conversations with doctors.

The testing kit is delivered by mail and easy to use. Essentially all you do is spit into a tube and then mail it to a 23andMe lab using the included, prepaid package.
After mailing your saliva sample to the lab, you should receive an email within six to eight weeks saying your results are ready to view in your online account.
The home genetics kit by 23andMe can detect predispositions for late-onset Alzheimer's, which is the most common form of the disease. People who get late-onset Alzheimer's are usually 65 and older and might not have family histories of the disease. These kits don't identify predispositions for early onset Alzheimer's.
To have a genetic predisposition to a disease doesn't mean you'll get it -- lifestyle and environmental factors almost always play much larger roles. These diseases are rare even among people with these dispositions. However, people who have these dispositions might want to talk to their doctors about their results.
Researchers have not found guaranteed prevention strategies to stop Alzheimer's from happening. The two biggest risk factors are age and genetics, and neither can be changed. However, studies have indicated that healthy lifestyle choices -- such as eating a good diet and exercising regularly -- can reduce the occurrence of Alzheimer's.
The company 23andMe was told by the FDA in 2013 to stop selling its home genetic testing kits. Since then, 23andMe conducted numerous surveys to prove that customers could understand the results of their genetic tests. That was the deciding factor in the FDA's recent decision.
There is still much debate in the medical community about the accuracy of genetic testing, and that includes these tests. That's partly why the FDA is requiring the 23andMe tests to include information about how to access genetic counseling services.
