How accurate is 23andMe?

At the laboratory, lab technicians extract this DNA and run it through a machine that searches for each of the 700,000 SNPs that 23andMe is looking at.

Why are my ancestry and 23andMe results different?

This is pretty common with DNA ancestry tests and it isn’t just a 23andMe thing. Companies like Ancestry.com or MyHeritage will give these sorts of results too. … These differences mostly come from how the computer algorithm splits up the DNA into thousands of windows, analyzing one window at a time.
