I've sent my spit off for more genetics tests than I can count.
Each one I've tried so far has offered a different experience, a different approach to how they present the data, or what information they provide — whether it's my great-grand relative or how much Neanderthal DNA I have.
Every so often someone asks me which test I would recommend.
Genetic testing companies have proprietary sets of data and different ways they analyze the data, which can also play a role in decision-making, but to me it all boils down to one question: What do you want to get out of the test?
Let's take the two direct-to-consumer ones I've tried out: AncestryDNA and 23andMe.
23andMe currently offers two versions of its tests:
The $199 version, which comes with both the health and ancestry components.
The $99 version, which will just have the ancestry test.
