Microbial’s Testing

the emerald test highgrade labs


Microorganisms and bacteria are everywhere in our world. They often can grow under the same conditions as cannabis and if consumed, these contaminants could lead to serious illness.

Highgrade Labs microbial screening ensures organisms’ presence are below a threshold considered safe for consumption.

What is our testing process?

We use both 3M Petrifilm plates and an Agilent AriaMX real-time PCR to test for microbial contamination. Call your state lab to talk about what specific microbial tests are required for you and how we test for them.

What products can we test?
