DNA can be used to determine a wide variety of things, including a person’s likely ancestry and whether they’re predisposed to certain health conditions. This is why 23 And Me’s new test can come in handy.
Learn More About Ancestry
One of the main reasons some people submit to DNA ancestry testing is to find out more about their ancestry. This may be particularly beneficial to people who know little to nothing about their family tree, such as those who are adopted. It isn’t easy to trace back a family history using genealogy alone, so even those who know a bit more about their family history may receive useful information.
Learn About Potential Disease Risk
The other potentially valuable information provided by a test is whether a person carries the genes that make them more likely to develop certain health conditions or pass the potential for these health problems to their children. Some of the conditions with genetic markers include Parkinson’s disease, Alzheimer’s disease, cystic fibrosis, and sickle cell anemia. Genetics may also determine whether a person is more likely to have metabolic issues, a predisposition to addiction, or reactions to medications.
Take Preventative Measures
Once a person knows that they may be more genetically predisposed to a certain condition, they can make diet and lifestyle changes to help limit their risk for these conditions. They can also speak with their doctors regarding any necessary screening they may need to try to catch the condition as early as possible if they do get it.
In some cases, people know they have a family history of a certain condition and don’t know whether they’re genetically inclined to get this condition themselves. Having genetic testing can be a way to potentially lessen their worries if it turns out that they don’t have the gene related to that condition, such as Alzheimer’s disease.
Even if it turns out that they may have a genetic predisposition, they can at least make preparations to make things easier if and when they do become ill or incapacitated. This includes things like making a will and a living will and arranging for who will be responsible for making decisions for them when they are no longer able to do so themselves.
