DNA is commonly used to confirm identity,
but it also is a powerful source of information that can reveal details of

Diagnostic tests can reveal predispositions for conditions ranging
from breast cancer to diabetes, Alzheimer's, and heart disease, while paternity
and ancestry tests can bring shocking and unwelcome revelations about family history.
