You can explore Genetic Test Providers (GTPs) and other health screening/program providers by location. We continually update the list of GTPs to include both those participating in HGTD and non-participating providers. Please Note: "Participating" genetic test providers have voluntarily contributed data on their business or research lab, as well as data on tests they offer. "Non-participating" genetic test providers are those we believe to be active but who do not currently participate in the HGTD database, and we may have missing or not up-to-date information on non-participating GTPs. Listing in the HGTD Database does not represent an accreditation or endorsement by the IPFD.
