'''Genetic testing''', also known as '''DNA testing''', analyzes an individual's genome to identify variations in DNA sequence and chromosome structure. Personal genetic information can be used to provide insights into ancestry, carrier status for heritable diseases<ref>https://en.wikipedia.org/wiki/Medical_genetics</ref>, prediction of disease risk, and other human traits<ref>https://en.wikipedia.org/wiki/Human_genetics</ref>. Due to the high costs of whole genome sequencing, various technologies (e.g. microarray testing) are commonly used to more efficiently target analysis of specific regions or variations <ref>https://www.cdc.gov/genomics/gtesting/genetic_testing.htm</ref>. While genetic testing is used and regulated in a clinical context, ''Direct-To-Consumer'' (DTC) companies also offer products focused on providing ancestry and health insights. | '''Genetic testing''', also known as '''DNA testing''', analyzes an individual's genome to identify variations in DNA sequence and chromosome structure.
