As a public service to cannabis laboratories, resultrust offers a national, at-cost inter-laboratory comparison (ILC) program to fulfill ISO quality requirements. Known by most scientists as round robins, an ILC is central to ensuring consistent, accurate analysis across scientific facilities.

We use third-party manufactured, DEA exempt reference materials in order to conduct the program nationally. In order to aid transparency, the administrative collection and dissemination of ILC performance data and reports is shared by laboratories willing to share in these duties.

This program is open to all cannabis testing facilities. Please click here to download the application for the next series.
