Direct-to-consumer (DTC) genetic tests, especially those for health-related purposes, are prohibited unless conducted with medical oversight to ensure informed consent and appropriate counseling. [65] This is due to concerns about the potential misuse of genetic data and privacy violations.
Some elective genetic and genomic tests require a physician to order the test to ensure that individuals understand the risks and benefits of testing as well as the results. Other DNA-based tests, such as a genealogical DNA test do not require a physician's order.
Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing .

[1] It is best known for providing a direct-to-consumer genetic testing service in which customers provide a saliva sample that is laboratory analysed, using single nucleotide polymorphism genotyping, [2] to generate reports relating to the customer's ancestry and genetic ...
GeneTree later returned to genetic testing in conjunction with its Sorenson parent company until it was acquired by Ancestry.com in 2012. [12] In 2007, 23andMe was the first company to offer saliva-based direct-to-consumer testing, [13] and the first to use autosomal DNA for ancestry testing.
The tests offered can vary significantly from one lab to another, including genes and alleles tested for, phenotype assignment, and any clinical annotations provided. With the exception of a few direct-to-consumer tests, all pharmacogenetic testing requires an order from an authorized healthcare professional.
Kit for genealogical DNA testing by 23andMe. Common specimen types for direct-to-consumer genetic testing are cheek swabs and saliva samples. [15] One of the most popular reasons for at-home genetic testing is to obtain information on an individual's ancestry via genealogical DNA testing and is offered by many companies such as 23andMe, AncestryDNA, Family Tree DNA, or MyHeritage.
