Announced or in pre-launch and not confirmed as operating. Services, prices and turnaround times are labelled as planned, not currently available. Not ranked.
Pre‑launch — website preview; operation not confirmed. The company's site is labelled a “Website preview”: online ordering is not yet open, and payments and customer accounts are not active. It asks customers to make contact before sending or dropping off samples, and describes report delivery as planned. PAL could not confirm that testing is currently being performed. The listed price and target turnaround apply once ordering opens.

The PAL Testing Evidence Score (v1) awards up to 30 points for information a testing business publishes about itself, shown on a 0–10 scale:
Anything we could not find earns no points and is shown as “Not found in public sources” — it is not treated as a “no”. Only laboratories that perform the analyses themselves, are operating, accept outside samples, have a confirmed facility in the country and document at least two of purity, identity and quantity testing are ranked. Coordinators, manufacturers with analytical services, global networks and planned facilities are listed separately without a number.
By the PAL Testing Evidence Score: up to 30 points for facility transparency, analytical scope, quality and reporting, and ordering transparency, based only on what each business publishes on its own website. Ties are broken by the number of documented testing services, then by name.
Country pages only include businesses whose own website places a facility in United States. Accepting or collecting samples from a country is not the same as testing there.
A laboratory runs the analyses itself. A testing coordinator takes orders and forwards samples to partner laboratories. Coordinators are listed separately and are not ranked against laboratories.
No. PAL Pro adds profile features for verified owners. It does not change any finding, score, eligibility or position.
It is listed without a number when it is not an independent laboratory, is not yet operating, its facility location is not confirmed, or it documents fewer than two of purity, identity and quantity testing. The reason is shown on its card.
