Providers · North America

North America

Independent labs and regional operators, by country — separate from the multi-country networks already listed on the main Providers page, which aren't repeated here. Mexico is covered on the Central America & Caribbean page, alongside its immediate neighbors rather than here.

All countries in this region were reviewed. The directory lists providers that met the selection criteria at the time of research. Public ratings and review counts are included where they could be found in open sources. There is no minimum review count. Providers that are not listed may contact us to request a review and possible inclusion. Listed alphabetically by country, then by company name.
