We are different


Dialed in for reliable results

Our lab is pursuing ISO accreditation through PJLA, a leading accreditation entity for testing and calibration laboratories.

Good science, like good business, is about reliable results. We’re actively pursuing ISO 17025 accreditation to show we’ve got our processes dialed (full accreditation expected in January). Reliability is a big benefit to any cannabis business. The safety of your end users — not to mention the success of your business — comes down to being able to offer a predictable experience. That’s what we offer.

Emerald Test: Cannabinoids Emerald Test: Microbial Emerald Test: Solvents

Tested for top performance

Protect your business’ prospects by working with an honest, scientifically reliable Seattle cannabis testing lab.

The Emerald Test® is the leading inter-laboratory comparison proficiency test for cannabis. It now measures the accuracy of participating labs’ microbial, residual solvent, and cannabis potency tests. Following a successful spring 2016 test for potency, we re-tested in all three areas and placed among the top-performing labs nationwide in all three areas. Bottom line: we can protect the health and safety of your end users — and the success of your business.

Logo: Puyallup Tribe of Indians

Rooted in meaningful tradition

Proudly serving the State of Washington with cannabis testing, we’re the first tribally affiliated cannabis testing lab in the U.S.

Our tribally-sanctioned lab came about in part to ensure safe medical marijuana for cancer patients within the Puyallup Tribe itself, which is why our lab is located within the tribe's cancer center. Known for being “a generous people,” the Puyallup tribe also sees our cannabis lab as an opportunity to support a more natural way of managing pain and a way to promote safety within Washington's emerging cannabis industry.
