Skirton H, Goldsmith L, Jackson L, O’Connor A. Direct to consumer genetic testing: a systematic review of position statements, policies and recommendations.

In healthcare settings, genetic tests to determine whether an individual had inherited a genetic mutation are ordered by a health professional, and the results are interpreted and conveyed to the patient by that person. However, direct to consumer genetic testing (DTCGT) has enabled individuals to purchase genetic tests and receive results without the intervention of a health professional. To inform a set of guidelines for consumers and health professionals, we undertook a systematic review of position statements, policies and recommendations on the use of DTCGT. We performed a search of seven databases and the Internet for relevant documents. The search terms were ‘direct to consumer’ and ‘genetic test', and documents in English published from 2002 to 2011 were included. The search retrieved 314 items, of which 14 were eligible for review. Five themes were derived from thematic analysis: motivation for use, potential benefits, potential harms, recommendations to guide consumers and need for research. The authors of these documents described more potential harms than benefits, but, although some stated that direct to consumer testing should be actively discouraged, others supported consumer rights to make autonomous choices. Further research into the impact of direct to consumer testing on health services and consumers is required to inform policies.
