The PathoSEEK™ Microbial Safety Testing Platform is the only method designed for and validated on cannabis flower, extracts, and a variety of infused products. The PathoSEEK platform uses qPCR technology, an established safety testing method in the food industry and medicine that has been used in several peer-reviewed studies.
Medicinal Genomics validated its PathoSEEK tests on a variety of cannabis matrices (flower, extract, and infused products) and provides extensive validation data upon request.
Every PathoSEEK test reaction includes an internal cannabis control, which gives assurance that each reaction has proceeded correctly and results can be trusted. No other cannabis microbial testing platform includes internal cannabis controls.
PathoSEEK kits include an optional decontamination protocol that prevents genetic material from a previous test from contaminating subsequent test runs. The DREAM™ PCR decontamination protocol simplifies lab operations by eliminating the need for isolated pre- and post-PCR cleanup areas to prevent cross-test contamination. Read More
We chose to use qPCR for microbial screening of cannabis at Digipath Labs for two reasons. First, Medicinal Genomics had already done the hard part, ie. creating the reagent kits for each microbial category and completing the validation on cannabis matrix to arrive at the more recognizable CFU/g conversion. That helps state regulators begin to understand the relationship of genomic screening to conventional plating methods such as 3M’s petrifilms. Second, there are many limitations with conventional plating methods (e.g. 3M’s petrifilms and BioMuirieux’s tube-based system). Medicinal Genomics' qPCR-based microbial detection platform allows for 48-hour turnaround of testing results and has built-in flexibility for the ever-changing state-by-state microbial testing guidelines. More importantly, qPCR provides an archived digital record of raw test results for those operating under ISO 17025 accreditation.
We chose PathoSEEK because it is more specific and faster than plate counting methods. All interactions with the Medicinal Genomics team have been positive and helpful. I would recommend the PathoSEEK platform to labs looking for a microbial testing platform because it’s designed for and validated on cannabis products.
Medicinal Genomics offers a variety of testing kits that cover each of the microbial tests that are required by the various state regulatory agencies. Medicinal Genomics also offers multiplex kits, which allow labs to test for multiple targets in one reaction, saving on time and labor, while increasing instrument run sample capacity by 33%.

*All Medicinal Genomics chemicals and reagents are manufactured in a facility certified to ISO 9001 standards.
Medicinal Genomics has done extensive research into the microbiome of the cannabis plant and shared its findings through peer-reviewed papers, articles, and videos. The hope is that these materials will educate the cannabis community about the many advantages of qPCR as a microbial testing method.
