The confidence interval indicates the level of variation in the metabolite profile. For example, a confidence interval of ≥95% to <98% indicates that the variation in the metabolite profile is within 2%–5% of the registered product sample for a specific product matrix.

The IQ ratings apply to those products demonstrating consistent “batch-to-batch” testing evidence, which achieve confidence intervals of at least 90% as specified in the Purity-IQ CAPS requirements. Product certification will be granted only to those products contained in the Purity-IQ Global Registry – Cannabis data library.
