23andMe is a privately held personal genomics and biotechnology company based in Mountain View, California. The company is named for the 23 pairs of chromosomes in a normal human cell. The company had a previously fraught relationship with the US Food and Drug Administration due to its genetic health tests, but as of October 2015, DNA tests ordered in the US include a revised health component, per FDA approval. 23andMe has been selling a product with both ancestry and health-related components in Canada since October 2014, and in the UK since December 2014.
