General Overview for 2023 Spring Round

An Emerald Badge™ was awarded to participating labs that met the criteria established by the ISO accredited PT manufacturer with input from The Emerald Test™ Advisory Panel. Labs receiving a Badge are recognized for their capabilities through inter-laboratory comparison with their peers for a given test.  The ILC/PT promotes transparency and enhances consumer confidence in the safety and the science which independent testing facilities contribute to the cannabis and hemp industries.

NOTE: The Emerald Test Badge does not imply regulatory compliance or laboratory accreditation. Alteration or misrepresentation of the badge will void the award and jeopardize future participation in the Emerald Test.     

Once again, thank you for participating in The Emerald Test™!
Should you have any questions or suggestions for improving the experience and value to your business, please let us know.
