About 1st Choice Labs

1st Choice Labs performs the required tests per the Michigan Marijuana Regulatory Agency (MRA) safety compliance facility guidelines. Test methods are selected based upon many factors including both internally and externally validated performance characteristics and statistics. Method performance must be documented and verified to meet all required performance criteria and must be evaluated by an independent, third-party ISO 17025:2017 accreditation body.

Each instrument method is built for the requirements set by the MRA. Variables such as column type, length, diameter, inlet temperature, oven temperature programing must each be selected to achieve chromatographic separation of all required analytes. Methods must be fully validated with all analytes meeting minimal acceptance criteria, including limits for precision and recovery, before being added under 1st Choice Labs scope of approved testing.
