The required sample size for microbial contamination testing is dependent on the size of your harvest batch or production batch per 4-110 – Regulated Marijuana Testing Program: Sampling Procedures.


We perform our microbial contaminant testing on QIAGEN qPCR instrumentation for E.coli and Salmonella screening and traditional culture plating for Total Yeasts & Molds.

Having the right equipment is critical, but it is only one piece of the Agricor Validated Laboratory System. Our lab is the ONLY cannabis testing facility set to the same standards of a Pharmaceutical Laboratory. By following Good Laboratory Practices (GLP) we deliver the most accurate results in the industry.
