When there are unexpected results, we work with clients to identify root causes and determine the right corrective actions. Regular clients receive this consulting support from our lab experts at no additional charge.
Cannabinoid and Terpenes are considered to be the physiological active constituents in cannabis, therefore, profiling these two components is typically essential. Select additional tests as needed or discuss with our representative to understand which tests are right for your products.

We currently quantitate for 10 cannabinoids. Our current method for potency utilizes a solvent extraction with homogenization, followed by quantitation on an HPLC/UV chromatography system.
CBD – Cannabidiol
CBG – Cannabigerol
THCV – Tetrahydrocannabivarin
CBDA – Cannabidiolic Acid
CBGA – Cannabigerolic Acid
CBN – Cannabinol
Δ9-THC – delta 9 Tetrahydrocannibinol
THCVA – Tetrahydrocannabivarinic Acid
Δ8-THC – delta 8 Tetrahydrocannibinol
THCA-A – Tetrahydrocannabinolic Acid
Terpenes are the organic compounds that provide the flavor, scent and aroma of cannabis plants. They can enhance the cannabinoids and play an important role in the therapeutic effects that different strains offer.
Moisture content is the percentage of water in the sample. Typically, cannabis should fall between 6% and 15% moisture content. A higher moisture content puts the sample at risk for microbial contamination.
Foreign Matter Inspection
A foreign matter inspection will determine if there is anything in the cannabis sample that is non-usable. This includes large foreign particles, hair, insects, mold colonies, or any other foreign particles.
Microbial Screen (or Microbial Safety Testing)
The microbial screen uses RT-qPCR (quantitative real-time polymerase chain reaction) to quantify bacteria found in the sample. This assay tests for TYMC (total yeast and mold), TAMC (total aerobic microbial count), E. coli species and Salmonella species. We use RT-qPCR over traditional plating methods because we are able to detect and quantify more species present in the sample in a shorter amount of time.
Mycotoxins are metabolic products of plant spoilage fungi that induce toxic responses when consumed. We test for the most relevant mycotoxins, aflatoxin and ochratoxin. Aflatoxin is produced by Aspergillus species and is a group 1 carcinogen, proven to cause cancer. We specifically test for aflatoxin B1, B2, G1, and G2. Ochratoxin A is a toxin produced by Aspergillus and Penicillium species. Ochratoxin is a group 2b carcinogen. Use of UPLC-MS/MS for highly sensitive mycotoxin detection and identification.
Water activity determines the susceptibility of cannabis to microbial contamination. Higher water activity means that the water in the sample is freely available for microorganisms to use.
Heavy Metal Screen:
Some elemental impurities have a high degree of toxicity and are of public health significance. Test will screen for heavy metal contaminants in medical cannabis.
Lead, Arsenic, Mercury, Cadmium, Chromium, Barium, Silver, Selenium
Residual Solvent Test
Some producers of cannabis products use solvents to extract and/or concentrate the active ingredients of cannabis, a list of residual solvents are tested for based on common extraction and concentration techniques in the industry.
(m,p-Xylene and o-Xylene)
Pesticide Residue Analysis
Tests for compounds named in the American Herbal Pharmacopoeia that are commonly used in cannabis cultivation. Use of UPLC-MS for highly sensitive pesticide detection and identification.
Aren’t all test labs about the same?
Atlantic Test Labs grew out of the pharmaceutical industry and adheres the strict Maryland testing regulations.
