DNA testing, also called genetic testing, is a medical test that checks the changes that occur in a person’s DNA.
According to MedlinePlus, these tests can determine if someone has a high risk of developing a health condition. People can also use a DNA test to learn about their genetic ancestry. For this purpose, a person’s DNA is compared to genetic references from large groups of people from various populations. If pieces of their DNA match the reference samples, the test can estimate or confirm an individual’s genetic ancestry from that population.
The National Human Genome Research Institute lists some
- helping doctors to provide the correct medication and dosage
- checking the severity of a disease
- detecting if a person has a genetic disorder to provide early treatment
- identifying gene changes that an individual’s children may inherit

How do DNA test kits work?
People who order a DNA test online will receive their kit through the mail.

If a person receives results that suggest they are at risk of developing a health condition, they can discuss their results with a healthcare professional.
How much do DNA test kits cost?
DNA test kits vary, but they can cost up to $135 if a person opts for more detailed reports, extra features, or there is an additional fee that covers shipping and laboratory work.
People can buy genetic tests to learn about their genetic ancestry, find new DNA relatives, build family trees, or check if they have a high risk of developing a disease or passing this risk on to their children.
