Avg purity

±0.33%

Std dev

Test breadth

What fraction of this lab's COAs report each test type. Real third-party labs typically run a consistent panel; sparse coverage on safety tests (endotoxin, sterility) is a common signal of HPLC-only purity work.

Endotoxin (LAL)0%

Sterility (USP <71>)0%

Observed signals

Purity standard deviation is unusually low across this lab's COAs. Real chemistry has variance.
Less than 10% of this lab's COAs include endotoxin testing. Likely an HPLC-only workflow.

Lab credibility is recomputed daily from the COA corpus. Score inputs: COA count, vendor breadth, purity distribution width, and fraction of COAs covering endotoxin + sterility tests. Heuristic — we're continually refining the weights.
