Book a Ticket to Reliability: Start Your Cannabis Lab Proficiency Journey with LIMS

CloudLIMS - Laboratory Information Management System (LIMS) Software Podcasts

In this podcast, we unravel the significance of proficiency testing (PT) in the cannabis industry with Morgan Keefer, Accreditation Officer II at A2LA.

We dive headfirst into the subject by demystifying PT, exploring its significance in ensuring the accuracy and reliability of cannabis test results. Morgan elaborates on the cannabinoids, microbial, and chemical attributes typically analyzed during PT.

Morgan’s expertise guides the discussion on the PT and interlaboratory comparison (ILC) requirements essential for ISO/IEC 17025 accreditation along with best practices for effective PT preparation. We also discuss the frequency of PT participation mandated by state regulatory bodies, highlighting the diverse timelines across different states.

Keefer explains how PT results are statistically evaluated and interpreted by PT providers to pass or fail a lab. She also discusses the impact of matrix interferences and sample heterogeneity on result accuracy. Furthermore, she provides tips for laboratories failing PT to determine the root cause and plan of action to remedy the failure. The discussion extends to practical examples of how PT has directly enhanced the operational efficiency and credibility of cannabis testing labs. Morgan also shares her foresight on advancements in PT for cannabis labs as testing requirements evolve. The podcast concludes with Morgan emphasizing the importance of informatics tools, including LIMS, in cannabis testing to support PT processes.

Tune in to the conversation for these and more such insights and gain a deeper understanding of the role PT plays in ensuring quality assurance and compliance in the dynamic and rapidly evolving cannabis industry.
