Laboratory Testing

Laboratory testing in cannabis refers to the analytical processes used to measure cannabinoid profiles, terpene composition, microbial contaminants, pesticide residues, and heavy metals in cannabis samples. These standardized tests employ techniques such as high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and microbial culture methods to provide quantitative data about plant chemistry. Laboratory analysis has become foundational to cannabis breeding, allowing cultivators and breeders to document genetic expression across growing environments and validate strain lineages through cannabinoid and terpene fingerprinting. Testing data informs selective breeding decisions by identifying which parent plants and offspring express desired chemical profiles consistently.

Breeders use laboratory testing to track chemotype stability across generations, compare cannabinoid and terpene ratios between parent lines, and confirm genetic purity in hybrid crosses. Detailed testing records enable breeders to establish reliable strain standards and make informed selection decisions based on measurable chemical traits rather than subjective observation alone.
