batches on file that failed testing
Failures are indexed exactly like passes, because an index that only shows the good news is an advertisement. How the record is kept
The rankings
Brands scored on testing consistency and depth of record, ranked within their own market. Scores are computed per market and are only comparable within one: each market has its own required panels, its own regulator, and its own depth of public archive, so a single cross-market list would rank brands against tests they were never asked to run. Every input behind a score is published on the brand's page.

Coming next
Brands join the ranking once their certificates are ingested and every number can link back to the issuing laboratory. Nothing is scored before that.
