Our Mandatory Testing Services

VRX Labs provides all California BCC phase I, II, and III mandated testing services to our customers, including Cannabinoids, Residual Solvents, Processing Chemicals, Pesticides, Microbiological Impurities, Mycotoxins, Water Content, Foreign Materials, Heavy Metals, and Terpenes. Minimum batch size is specified by the state as the minimum threshold required. When appropriate due to clear crop heterogeneity, VRX Labs will counsel customers on the statistical significance of large batch sampling, describe methods by which it may be optimized, and offer solutions that maintain results robustness.

Benefits of Testing for VRX Customers and Product Consumers

Accurate Profiling and Labelling

VRX Labs will analyze the cannabinoid and terpene contents to provide accurate information for growers to fine-tune the flavor and potency of their cannabis products. Accurate profiling will give consumers the confidence needed when selecting the right product to purchase.

THC, CBD, and CBG are the compounds that give cannabis its potency.  We test for all major cannabinoids (up to 14 different compounds) so we can provide producers with accurate labeling information.

The potency for dried harvested cannabinoids will be reported as a percentage. For manufactured cannabis products such as oils and edibles, the potency of cannabinoids will be reported in milligrams per gram.

Terpenes are responsible for the specific aroma and flavor of each individual cannabis strain. The unique odors and tastes of terpenes help consumers differentiate one strain from another and understand what they like or dislike. VRX Labs will provide growers and producers with a precise measurement of terpenes present, which will help sophisticated consumers choose a more satisfying product.

Genetic profile analysis will identify the following plant profiles:

Plant Type I Plant Type II Plant Type III Plant Type IV
THC-Dominant THCa:CBDa Hybrid CBDa-Dominant CBGa-Dominant
CBDa:- CBDa:+ CBDa:+ CBDa:-
THCa:+ THCa:+ THCa:- THCa:-

 

Precision is important when identifying CBD-dominant seeds. Genetic markers are used to find seeds within a population that are programmed to produce high amounts of CBD. A marker is selected on the genome of a cannabis DNA strand based on its proximity to the desired CBD genetic trait. The genetic information contained at the site of the marker is used to find members of the same population that share CBD-dominant genes.

Consumer Product Safety

Safety tests performed at VRX Labs include analysis for pesticides, heavy metals, debris, solvents, processing chemicals, and microbiological impurities.  The latter is especially important as legal cannabis is now available for purchase by a large proportion of the population, including older individuals and immunocompromised patients.
