23andMe is a privately held personal genomics and biotechnology company based in Mountain View, California, that claims to be developing new methods and technologies that will enable consumers to understand their own genetic information. The company is named for the 23 pairs of chromosomes in a human cell. 
Main categories on the corporate website: The Spittoon (blog), Ancestry (Relative Finder, global origins, ancestral lineage), Health (carrier status, disease risks, drug response), how it works (spit kit), Research. 
There is one DNA test available which genotypes around 570,000 SNPs of the human genome with a Illumina OmniExpress Plus customized chip. The test provides ancestry and health information in the United Kingdom, Ireland and Canada. In other countries the test currently only provides ancestry information.
The corporate website under sign up provides a free demo account to check the product features.
Ancestry / genetic genealogy
For genetic genealogists the following DNA test results are interesting:
- Autosomal DNA + X-DNA: very good data to trace deep and recent ancestry and find relatives is provided. The test in v3 delivers about 956,000 SNPs on the 22 autosomes and the X-chromosome. This is about 10% of the existing human SNPs  and currently a very good coverage.
- Paternal line - Y chromosome (Y-DNA): basic data for surname projects (paternal clans) and male related prehistory migrations is provided. About 2,000 SNPs are tested and the result mapped to a haplogroup tree with medium resolution (corresponds largely with the outdated YCC tree of 2008). External tools can help to update the Y-DNA haplogroup nomenclature, but can hardly increase the resolution of v3 results.
- Maternal line - mitochondrial DNA (mtDNA): basic data for female related prehistory migrations is provided. About 2,500 SNPs (~15% of mtDNA) are tested and the result mapped to a haplogroup tree with good resolution. External tools can update the assignment to a mtDNA haplogroup and sometimes increase the resolution of v3 results.
All DNA test results can be downloaded as raw data. The various file formats (v2, v3) are widely recognized by external tools.
A range of different chips have been used for the 23andMe test since the introduction of the service:
- v1: November 2007* v2: September 2008, ~555K SNPs* v3: November 2010, >900K SNPs* v4: November 2013, ~570K SNPs
Scientists and genealogists

The 23andMe scientists have published a number of papers in scientific peer-reviewed journals using data from 23andMe customers who have consented to have their information used for research purposes. See the list of 23andMe publications for details.
External tools, further investigation of raw data
With the raw data a variety of tools can be used to explore your DNA further.
Autosomal DNA (atDNA) and full genome
- Autosomal DNA tools
- Admixture analyses. Complementary and sometimes refining to Global Similarity, e.g. Doug McDonald BGA, Dodecad Ancestry Project, Eurogenes, etc.
- mtDNA haplogroup nomenclature: James Lick's mthap - utility for analysing mtDNA haplogroup data (based on latest PhyloTree.org, Beta Test of new versions)
- Y-DNA SNP identifying: YDNA SNPs Comparison Project (Adriano Squecco, daver.info) since v2 new SNP have been found, but with v3 and in 2012 the potential of new discoveries seems low.

Focused on genetic genealogy topics.
- April 2006: 23andMe was founded by Anne Wojcicki and Linda Avey.
- Nov. 2007: The initial cost of 23andMe's product for US-consumers was $999 (580,000 SNPs using Illumina technology).
- Jan. 2008: the service was extended to Canada and most countries in Europe.
- Sep. 2008: the test was updated from V1 to V2 and the cost reduced to $399. This was possible with the Illumina HumanHap550-Quad+ chip, capable to read about 600,000 SNPs (expanded range) from all Chromosomes and the mtDNA.
- Sep. 2009: Co-founder Linda Avey leaves 23andMe to focus on Alzheimer's Research. 
- Nov. 2010: 23andMe introduced an alternative pricing option of $199 with a required one-year subscription of $5 a month. The newly introduced V3 test reads almost 1,000,000 SNPs with the Illumina OmniExpress Plus customized chip (base OmniExpress 733,202 SNPs). For both ancestral lineages (mitochondrial DNA and Y-DNA) over 2000 SNPs are recorded making possible Haplogroup Discovery of over 750 maternal lineages and over 500 different paternal lineages.
- March 2011: the pricing was changed to $99 with $9/month (for at least one year). This subscription would provide subscribers with updates on discoveries made about their DNA over time. A single-fee payment of $399 without the commitment continues also to be available.
- June 2011: On the SCGS-Meeting 23andMe stated to have tested about 75,000 individuals.
- June 15, 2011: 23andMe announced in three and a half years of service their database has grown to include the DNA data of more than 100,000 people. Other statistics include 60,000 users had completed on average 10 surveys, 100,000 community forum posts, more than 60,000 pairs of relatives have been discovered, 57% of 23andMe users are male, 47% share their data with other users, and 12% have multiple ancestries.
- Sep. 27, 2011: 23andMe announced at Health 2.0 in San Francisco a limited enrollment pilot program for current members called Exome 80x. The test will measure 50 million base pairs of the participant's exome at a cost of $999. This new test will not be good for ancestry as the test focuses on the exome and will not measure much of mitochondrial or Y-chromosome DNA.
- Nov. 2011 technical status info: v3-only raw data download has 960,520 SNPs (1,764 for Y-DNA and 2,459 for mtDNA). Relative Finder looks for segments of DNA from a common ancestor (IBD = Identical By Descent). Segments of at least 7 cM (centiMorgans) and at least 700 SNPs are reported. Additional segments need to be at least 5 cM and have at least 700 SNPs.
- Dec. 2011 / Jan. 2012: major discussions about changes of terms for expired PGS subscription customers. Together with customer wishes for more ancestry and genealogical functions a "Ancestry Ambassador Group" was founded, to further the interests of the genetic genealogy community and to promote autosomal DNA testing for genealogy. Members are CeCe Moore, Dr. Ann Turner, Larry Vick, Dr. Tim Janzen, Andrea Badger and Shannon Christmas. 
- May 10, 2012: The subscription model was eliminated and a single $299 price introduced. Before: $99 with required 1-year subscription to 23andMe's Personal Genome Service® billed at $9 per month (incl. updates on discoveries made about DNA over time). There was also a Prepaid option for $207 which includes the subscription for 1 year. The third option was a lifetime subscription for $399. 
- December 11, 2012: Ancestry Composition (Ancestry Painting 2) released with much more detail comparing to 22 reference populations builded upon customers and public data sets. Company has more than 180,000 customers and sets growth goal of one million customers: single price drops to $99.
- April 25, 2013: 23andMe has genotyped more than 250,000 customers.
- May 2013; The ancestral composition of 23andMe's database is as follows: about 65% are of northern European ancestry; 6% African American; 5% eastern Asian; 4.5% Latino; 3.7% southern European; 2.6% South Asian.
- November 2013: 23andMe introduces the V4 chip (577,382 SNPs) test which tests for significantly less variants then V3 (967,000 SNPs) and is not compatible for transfer to FTDNA Family Finder.
The company has received Series A, B, C and D funding from several prominent technology and health science companies, strategic angel investors and venture capital firms: 
- May 2007 Series A $9M  : Google Ventures $3.9M, wikipedia:Genentech, New Enterprise Associates, MDV - Mohr Davidow Ventures (sold their stake to invest in Navigenics)
