Quality Assurance

Science Driven – Patient Focused

At Eastern Analytical Labs, we believe that good science leads to reliable results. We follow all the ISO/ISE 17025:2017, Federal, and MCA requirements for cannabis testing. The safety of the end-user patient drives our process.  This includes:


Equipment - All testing equipment is maintained to the highest standards. There are three levels of acceptable maintenance: Operational Qualifications (OQ), Performance Qualifications (PQ) and System Stability Check (SST).  At Eastern, our equipment is Operational Qualified at the highest level to ensure our systems function like new.

Laboratory Personnel - Our personnel is highly-educated and well-trained.  (See their bio’s).  In addition, our lab team goes through regular proficiency testing on all methods used.

Quality Control of Samples – Each process is fully documented as to how to conduct the test, including pre-testing calibration, and each employee is required to follow the process. This ensures repeatability, correct extraction, measurement, and results and that there is no carryover from previous analysis.

Reference Materials and Chemicals Used – The safety and quality of the materials used are of prime importance.  At Eastern, we only use materials supplied by qualified, reputable, certified, and accredited suppliers.  In addition, EAL audits its suppliers regularly to ensure compliance.
