IGS was established to facilitate foreign patient access to cutting-edge US-based genetic testing, variant interpretation, and evidence-based medical management guidance.

In addition to serving individual patients (and their local physicians) in pursuit of genetic testing solutions, we also help guide local physician, pharmacy, and/or health care marketing groups in local promotion of US-based genetic testing and analysis services.

Finally, IGS lends its lab expertise via consulting and partnership arrangements to develop and build local genetics labs in foreign markets, in order to improve local access to genetic testing.
