Hiring a DNA Testing Company
DNA testing has become an accepted tool for identifying ancestors and for verifying genealogical leads. It is also used frequently to learn about our deep ancestry. Testing your family DNA sometimes results in finding cousins who may have more genealogical information than you.

DNA Testing Companies[edit | edit source]
The main five main companies for genetic genealogy are 23andme, Ancestry, FamilyTreeDNA, LivingDNA, and MyHeritage. All five of these companies sell DNA kits, predict your ethnicity results, generate a list of your genetic relatives who are also in the database, tell you the amount of centimorgans you share with each match, and predict the relationship between the two of you, let you see lists of people who match you and someone else on your match list, let you add your family tree, and allow you to download your raw data. All of them use a microarray to test between 620,000-665,000 SNPs and all have a base price on their basic autosomal DNA test between $79 and $99. All five companies are highly reputable and will do a great job if you choose to buy a DNA test from them.
In addition to these five companies, GedMatch is also a key genetic database. GedMatch, however, does not sell DNA kits, you must buy a kit from another company and then upload your DNA raw data file into GedMatch.
If you are looking for someone you gave up for adoption, it is important to get your DNA in all the databases. That way you have the best possible chance of finding the one person you are looking for.
