A genealogical DNA test looks at a person's genetic code at specific locations. Results give information about genealogy or personal ancestry. Generally, these tests compare the results of an individual to others from the same lineage or to current and historic ethnic groups. The test results are not meant for medical use. They do not determine specific genetic diseases or disorders (see possible exceptions in Medical information below). They are intended only to give genealogical information.

Famous quotes containing the words test and/or dna:
“First follow Nature, and your judgment frame
By her just standard, which is still the same;
Unerring Nature, still divinely bright,
One clear, unchanged, and universal light,
Life, force, and beauty must to all impart,
At once the source, and end, and test of art.”
—Alexander Pope (16881744)
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
