The GeneTests Laboratory Directory and Clinic Directory list information voluntarily provided by laboratories about their tests and services and by genetics clinics about their clinical genetics services. As appropriate, users can search by a disease name, gene symbol, protein name, clinical genetics service and information about a lab/clinic, such as its name, director and location. Clinics in the USA can also be found via a map-based search. Together, GeneReviews and the GeneTests directories support the integration of information on genetic disorders and genetic testing into a single resource to facilitate the care of patients and families with inherited conditions.
