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.

Only countries where a qualifying company was actually found appear below — a missing country hasn't been researched yet, not ruled out. A company qualifies if it runs (or plausibly runs) a real physical operation, its rating is 3.0★ or higher wherever we could find one (Google preferred; Trustpilot, Yelp, BBB, or a local review aggregator when Google itself wasn't reachable), and nothing about it reads as negative. There's no minimum review count — a handful of genuine positive reviews counts the same as a few hundred. Some of these companies run their local site as part of a wider partner or franchise network rather than a single standalone lab; where that's the case, it's noted in the city field rather than hidden. Listed alphabetically by country, then by company name.
