Let's Go Back To The Basics
There are quite a few DNA testing labs available to the public now. And, many of the labs use their own specific criteria for testing your DNA and giving you the results. DNA testing is still in it's infancy, and many more years will be needed to perfect the science to the point where the results they can offer is more difinitive than now.
The most specific results can now be obtained when one gets a "Genetic Genealogy" test done. A Genetic Genealogy test can tell you if you're related to someone else who has also tested, in a genealogical time-frame. (within the last 5000 years, or so.) That means, a mitochondrial DNA test (mtDNA) or a Y-DNA test. (the Y chromosome tracks the male, or father-to-son DNA line) mtDNA testing can give results that track the mother-to-daughter line (but, I should mention that mothers give mtDNA to all of their offspring)
"Anthrogenealogy" DNA tests are less specific. They are the tests that look at your autosomal DNA (sometimes referred to as "Admixture"), and also mtDNA and Y-DNA tests that are designed to determine your "Haplogroup", sometimes only from one line of your ancestors. These tests are designed to help determine the origin of your distant ancestors (outside of a genealogical time-frame...or, more than about 5000 years ago).
Certainly, I'm no expert on DNA testing, but I do understand the differences between the DNA testing offerings. My suggestion to everyone considering DNA testing, is to read all that you can find about the science, and to determine why you want to be tested.....to determine if you're related to someone else who has or will test, or to help determine where "some" of your ancestors "may" have lived.
But, if you have lots of money to spend any way you choose, you can disregard all of what I've said.
