Cannabis Lab Locations
Six licensed cannabis testing laboratories across Arizona, Illinois, Massachusetts, New Jersey, New York, and Ohio — delivering fast turnaround and local regulatory expertise in every state we serve.
Accreditations & Certifications
Our cannabis laboratories hold ISO/IEC 17025 accreditation and state-specific cannabis testing licenses, ensuring your results meet the highest standards of scientific rigor and regulatory acceptance.
Biological Potency
Accurate potency testing for THC, CBD, CBG, CBN, and full cannabinoid profiles using validated HPLC methods, providing precise data for label compliance and product formulation.

Cannabinoid Profile Testing
Comprehensive cannabinoid profiling covering more than 20 cannabinoids including Δ9-THC, THCA, CBD, CBDA, CBG, and minor cannabinoids to support full-spectrum product development and state compliance.
Cannabis Terpene Profile Testing
Quantitative terpene analysis of over 40 terpenes by GC-MS, enabling strain characterization, quality control, and consumer-facing transparency for flower, concentrates, and infused products.
Cannabis Pesticide Testing
Multi-residue pesticide screening panels covering hundreds of compounds using LC-MS/MS and GC-MS/MS, meeting all state-mandated action limits and protecting consumer safety.
Cannabis Microbiological Analysis
Microbial safety testing for total aerobic count, yeast and mold, coliforms, E. coli, Salmonella, and Aspergillus species — essential for state compliance across all product categories.
Cannabis Heavy Metals Testing
ICP-MS analysis for lead, arsenic, cadmium, and mercury in cannabis products, providing accurate quantification at trace levels to meet state action limits and ensure consumer safety.
Cannabis Residual Solvents Testing
Headspace GC-MS/FID testing for residual solvents including butane, propane, ethanol, and other Class I/II solvents in concentrates and extracts, ensuring compliant manufacturing processes.
Cannabis Mycotoxin Testing
Sensitive LC-MS/MS detection of aflatoxins (B1, B2, G1, G2) and ochratoxin A in cannabis flower and derived products, supporting grower and processor compliance in states with mycotoxin requirements.
Hop Latent Viroid (HLVd) Testing
PCR-based detection of Hop Latent Viroid, the silent epidemic decimating cannabis yields, enabling early identification and containment before the pathogen spreads through your cultivation facility.
Cannabis Moisture Content Testing
Precise moisture content determination for cannabis flower and biomass, supporting curing optimization, shelf-life prediction, and compliance with state moisture limits for packaged products.
Cannabis Water Activity Testing
Water activity measurement to predict microbial stability and mold risk in cannabis flower and concentrates, providing a rapid quality indicator that correlates directly with shelf-life and consumer safety.
Cannabis Foreign Material Analysis
Visual and instrumental inspection for foreign matter including glass, metal, sand, insects, and other contaminants in cannabis flower and processed products, meeting state visual inspection requirements.
Vitamin E Acetate Testing
Targeted LC-MS/MS analysis for vitamin E acetate (tocopheryl acetate) in cannabis vape cartridges and oils, following the EVALI outbreak guidance from public health authorities.
Cannabis Genetic Sex Testing
Early-stage DNA-based sex determination of cannabis seedlings, enabling growers to identify and remove male plants before they can pollinate female crops and reduce cannabinoid yields.
Cannabis Stability Testing
Real-time and accelerated stability studies for cannabis products including edibles, tinctures, topicals, and flower — supporting label claim substantiation, shelf-life determination, and packaging validation.
Why Regulatory Readiness Matters
Cannabis regulations change frequently. Limits shift, new analytes emerge, and testing requirements evolve. While others scramble to catch up, we anticipate what's coming.
Day-One Implementation
New regulations effective? We're testing to them immediately. No delays, no scrambling, no missed deadlines.
Proactive Monitoring
We track regulatory changes across all our licensed states, identifying trends and preparing for updates before they impact your operations.
Compliance Guidance
Beyond testing results, we provide context on regulatory changes and how they affect your products, helping you stay ahead of the curve.
Licensed in Six States
Physical lab presence in each state ensures we understand local nuances and maintain direct relationships with regulators.
Specialized Testing for Complex Products
Certain testing scenarios require specialized knowledge. These are areas where our experience makes the difference.
Edible Homogeneity Challenges
Edibles with uneven cannabinoid distribution fail compliance and create liability risks. Our specialized sampling and testing protocols identify hot spots and ensure batch consistency before products reach the market.
Multi-Product Testing Expertise
Different product matrices — from beverages to concentrates — demand specific analytical approaches to meet regulatory requirements. Our validated methods handle complex formulations that challenge standard testing protocols.
Challenging Sample Matrices
Complex formulations — from nano-emulsions to high-fat edibles — require specialized extraction and analysis techniques. Our validated methods deliver accurate results where standard protocols fail.
Built on Trust
In an industry where accuracy is everything, our clients choose us because they know our results are dependable. We've earned that trust through consistent performance and transparent processes.
