Testing turns a physical batch into a document a shopper can review. Understanding the steps makes the resulting report easier to interpret.
Sampling
A sample is drawn from a defined batch. Sampling procedure matters, because results are only as representative as the sample taken.
Preparation and analysis
Samples are homogenized and extracted, then analyzed. Cannabinoid profiles are commonly measured with chromatography methods; contaminant panels use different instrumentation appropriate to each analyte class.
Quality controls
Laboratories run calibration standards, blanks and control samples. Accreditation to a standard such as ISO/IEC 17025 indicates an assessed quality system, and is usually stated on the report.
Reporting
Results are issued as a certificate of analysis tied to the batch, with test dates, methods and limits. A report is a snapshot of a sample at a point in time, not an ongoing guarantee.
