Lab reputation
Every lab builds a public win/loss record from dispute outcomes. Permanent, transparent, cannot be edited.

How labs get listed
Labs don't sign up directly. A lab appears when a brand submits a claim referencing their COA. Presence is earned through usage, not partnerships.
The record
WinsDisputes where the lab's results were upheld
LossesDisputes where the lab's results were found inaccurate
Win rateWins / (wins + losses)
- Challenge rejected = lab gets a win
- Challenge upheld = lab gets a loss
- Inconclusive = no change
Why it matters
- Brands choose labs with strong records -- those results are harder to challenge
- Consumers check the lab's record to gauge result reliability
Lab reputation here reflects dispute outcomes within ProofLabel only -- not external accreditation or certifications.
