Our in-house pesticide chemist, Kyle Shelton, helps us perform medical marijuana tests with industry-leading expertise.

When it comes to the success of your medical marijuana business or grow operation, nothing could be more important than using a reputable medical marijuana lab. Testing ensures your protection from a compliance perspective, but it's also critical to the health of immune-compromised people who use cannabis as medicine.

Our industry-leading science team and state-of-the-science equipment make us the go-to choice for medical marijuana lab testing. Seattle's medical marijuana community deserves a testing lab that takes accurate testing as its sacred duty. We are very close to being able to provide testing for heavy metals and full I-502 cannabis testing for medical cannabis. Stay tuned for updates.

Moisture & Water Activity - $25

Our method for testing moisture content in cannabis uses both a loss on drying technique to determine percent moisture, and measurement of water activity. Water activity is measured using an Aqualab DUO 4TE, the industry standard for dew point moisture analysis. USP <1112> outlines water activities required to support microbial growth.

Mycotoxin Testing - $50

Mycotoxins are known carcinogenic compounds produced by molds. We use an enzyme-linked imunnoassay (ELISA) and LC/MSMS to detect and verify the presence of Aflatoxin B1, B2, G1, G2, and Ochratoxin A in cannabis flower.

Pesticide Testing (150 analytes) - $249

Pesticides are commonly used to protect crops from diseases and pests. However, no pesticides have been validated for use on cannabis flower, which leads to people misusing and overusing these harmful products. In order to achieve accurate quantitation of pesticide residues, we use a Shimadzu 8050 LCMS Triplequad to detect 150 pesticides required in WA State for 502 and DOH accreditation.

Heavy Metal Testing

We perform metals analysis using a Shimadzu ICP-MS 2030 (Inductively Coupled Plasma Mass Spectrometer). Digestions are accomplished on an Anton Paar Multiwave GO. Our metals list covers the WA State DOH required heavy metals arsenic, cadmium, lead, and mercury in addition to a broad panel of inorganics. Methods include USP <221> and <222>, EPA 200.8, and a modified EPA 6020.
