374 Labs passes third party proficiency test

Accurate test results are paramount in any laboratory setting. As the State of Nevada continues to develop a proficiency testing program, 374 Labs elected to participate in, and has recently completed, an independent third party proficiency examination through Emerald Scientific.

The Emerald Test®, offered semiannually, is an ISO 17043 accredited proficiency program intended to standardize the accuracy and reporting of potency results across the industry. The goal of the Emerald Test®, as stated on their website, is “Consistent, accurate and quantifiable lab test results expected by state agencies, dispensaries, growers and consumers.  Without it, confidence at all levels will be eroded.”  The single-blind sample submitted to participating laboratories consists of a cannabinoid matrix bearing unknown quantities of THC, THC-A, CBD and CBN. Participating labs must analyze this sample and report results directly to Emerald Scientific.

374 Labs participated in the 2015 round of potency proficiency testing and earned the Emerald Certificate on the first attempt.
 
The results reported by 374 Labs were within ± 2% of the actual value for the sample. What does a ± 2% rating really mean? An accuracy rating of 2% is based on percentage deviation of the reported analytical result from the real value of the sample, not deviation of absolute weight percent. For example, if the actual THC concentration in the sample was 20% by weight, a 2% accuracy rating would entail a reported analytical result between 19.6% - 20.4%. A paper published by the Society of Cannabis Clinicians in 2011 regarding the accuracy of potency testing found the range of reported results among cannabis labs participating in  a ring test to be 20%, which, when applied to the above hypothetical true THC concentration, would result in reported analytical results between 16% - 24%. A link to the complete paper regarding the accuracy of potency testing can be found here:

While no proficiency program has yet been implemented in the State of Nevada for potency, or for any other required assays, 374 Labs remains committed to offering the highest level of service to its customers and patients.
