Lab Testing Profiles

Lab testing profiles document the chemical composition of cannabis samples through standardized analytical methods, typically measuring cannabinoids (THC, CBD, CBN), terpenes, residual solvents, microbial contaminants, and heavy metals. These profiles provide objective data points independent of sensory description, enabling breeders and cultivators to correlate genetics with measurable compound ratios. Testing standards vary by jurisdiction and laboratory, affecting reproducibility and comparability across results. Modern cannabis genetics work increasingly incorporates lab data to track consistency within strain families and identify phenotypic variation. Terpene profiling from lab analysis has become a primary tool for documenting aromatic chemotypes within seed lines, complementing traditional breeding records.

Breeders use lab testing profiles to stabilize desired cannabinoid and terpene ratios across generations, establishing strain baselines and selecting parents that reliably produce target chemical profiles. Systematic testing also helps identify chemotypic consistency within seed populations and track genetic drift over successive generations.
