I swabbed my cheeks and spat in vials to test the top seven ancestry DNA test kits and uncovered surprising details about my heritage in the process. I found that Ancestry.com’s DNA test is the best because it is affordable, contains personalized results and has the largest database of any company on the market. If you’re interested in paternity testing, Paternity Depot is our top choice because it’s the most affordable and offers great accuracy. DNAFit is the best health and fitness test because you get your results in 10 days. If you’re testing your dog, Wisdom Panel 4.0 is the most affordable and tests the most dog breeds.
