Potency Testing Methods

Potency testing methods are standardized laboratory procedures used to measure cannabinoid profiles in cannabis plant material and final products. Common approaches include high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS). These techniques quantify THC, CBD, and other cannabinoids by separating and identifying chemical compounds. Testing methodology significantly influences reported results; different methods may yield varied cannabinoid percentages from the same sample. Breeders and seed companies rely on consistent testing protocols to accurately document strain genetics and guide selective breeding programs. Standardization across testing facilities remains an ongoing challenge in the cannabis industry.

Breeders use standardized potency testing data to identify parent plants with desired cannabinoid profiles and track trait expression across generations. Reliable testing methods enable evidence-based selection for cannabinoid ratios rather than reliance on phenotype observation alone.
