What can a DNA test reveal?
These tests analyze a sample of a person’s DNA and look for specific changes associated with different conditions. Often, test results can help doctors diagnose and predict a person’s risk for developing a disease. Other DNA tests can tell people about whether they’re predisposed to certain traits.
Can DNA tests be used against you?

Can a DNA test show your nationality?
Autosomal testing, Y-DNA, and mtDNA testing can be conducted to determine the ancestry of Native Americans. … Thus, being in one of those groups provides evidence of potential Native American descent. However, DNA ethnicity results cannot be used as a substitute for legal documentation.
What specifically do they look for in the DNA?
What is a genetic test? A genetic test looks at your DNA to find changes (variants) that cause disease or put you at greater risk to develop disease. DNA is the code our bodies use to make genes, and genes are the instructions for our bodies.

Can siblings have different DNA?
Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins.
Do we own our DNA?
Genetic and genomic research requires access to human DNA from biological specimens, which can be stored and used in multiple areas of research. Being able to use samples of tissue however is different from owning them. Case law in Australia states that there is no ownership of the body or body parts.
