What is it?

The Emerald Test

Inter-Laboratory Comparison and Proficiency Test for Cannabis Testing Labs

The Emerald Test® is an Inter-laboratory Comparison Proficiency Testing (ILC/PT) program for evaluating how accurately  testing labs perform, by comparing how well the lab measures an anonymous sample. These programs are the standard in many testing industries, including environmental, food, pharmaceutical, water, petrochemical, and others. The results provide a benchmark for the industry in general, by elucidating how well the labs perform collectively. The data can also be used by the individual labs to demonstrate proficiency to their customers, or used internally to identify areas in need of improvement. The ILC/PT is often used by state regulatory bodies as a component of certification programs, and is commonly a requirement for various ISO certifications. Finally, the results provide a measure of assurance and reliability to the industry as a whole, and particularly to those who depend on the testing lab’s results for safety, health, and product performance.

The Emerald Test®  is offered twice each year (though individual PT’s are always available).

How it works

The Emerald Test® takes place in the Spring and Fall of each year, with enrollment open for a set period of time.  The components of each test are determined by the Emerald Test Advisory Panel.  Test Samples are manufactured by an ISO 17043 accredited PT provider and require overnight shipping.  After receiving and testing the sample,  labs have a window in which to complete the test and submit their results through an electronic data portal. Data analysis provided by AOCS using software designed to meet requirements of ISO 13528:2015.

Labs will receive their individual results, and once analysis is complete, will receive the overall test results, so as to see how they performed in relation to their peers.  Individual lab data is held in strict confidentiality, however cumulative (anonymous) data of all participants will be used for a variety of analyses, and may be published in appropriate journals and/or websites.  Labs that perform within a specific tolerance will be awarded an Emerald Test Badge, and all participants will be listed on the Emerald Test website.

The Badge

An Emerald Badge will be issued to top performing labs.  The criteria for selecting labs which receive an Emerald Badge is defined by the Emerald Test Advisory Panel.  In previous, single-analyte tests, the badge was awarded to labs which performed at or below =/-10% of the actual value of the test.  However, with multiple-analyte tests,  the calculations become more difficult.  The Advisory Panel has recommended the use of  a Z score of +/-1 to qualify for the badge.  This is a more robust and rational statistical evaluation that will be performed after all of the test data has been received.

Badges come with a one-year license, and can be used on the lab’s website, or for any digital or print marketing campaigns.  Display of the Emerald Test Badge demonstrates to its customers a lab’s proficiency and commitment to excellence.

THE TESTS

The Spring 2016 Emerald Test offered both a Potency Test and a Residual Solvents test. Labs chose to take either or both tests.

EMERALD-PT-BOXThe Potency Test was comprised off a 5-part cannabinoid matrix in 1mL of methanol.  The test contained from 10-1000 µg/mL of THC, THC-A, CBD, CBD-A, and CBN.

 

 

 

Shopify-residual-solvents-Box-400x400The Residual Solvent Test consisted of 5 specific solvents in a matrix of 10, in 1mL DSMO.  Labs were to  identify from10-1000 µg/mL of n-Heptane, n-Hexane, n-Butane, Isobutane, and Isopropyl Alcohol.

 

 

 

In conjunction with the Spring 2016 tests, we also offered:

Submitting and reporting

Once labs completed the test, results were submitted though an online portal.  Labs then received an email with a link with embedded credentials to securely input their results.    All labs must have submitted their results by Friday, April 22, at 5pm EST.

All submitted data was then  transferred to AOCS (American Oil Chemists Society) for processing and analysis using ISO 13528:2015 software and standards for ILC/PTs.  Reports were then  generated and returned to participants by May 13th.
