The Emerald Test™ is an Inter-Laboratory Comparison Proficiency Test (ILC/PT) Program that provides cannabis and hemp testing facilities with Proficiency Tests (PTs) to help meet their internal Standard Operating Procedures (SOPs), regulatory compliance, and ISO/IEC accreditation needs.

Introduced in 2014, The Emerald Test™ has consistently been offered twice per year, and is the longest running program of its kind. To ensure the quality of the PTs used in the Program, and the accuracy of the results, all PTs are produced by ISO 17043 accredited manufacturers. And in addition to those offered in the Program, individual PTs can be purchased at any time throughout the year.

Through the participation of labs around the world, The Emerald Test™ helps cannabis and hemp testing laboratories demonstrate competency, validate their measurement processes, and affirm their ability to meet regulatory requirements for licensure. (courtesy of
