Proficiency Testing for Oil

Proficiency testing is a powerful quality assurance tool that enables laboratories to monitor their performance and compare their results against similar laboratories.

How data is generated and used during proficiency testing:

  • Samples are shipped to participating laboratories based on the shipping deadlines.
  • These samples are processed by the testing laboratory using normal cannabis testing procedures.
  • Results are submitted to PTC by the deadlines indicated in the instructions.
  • Detailed confidential results are reported back to the testing laboratory.
  • Sample summary report containing detailed summary statistics and graphical representation of the data.
  • Laboratories can then compare their results against every other laboratory participating in the same round.
  • The data can be used to reinforce testing methods or allow laboratories to identify and make adjustments to their procedures.
  • Subsequent rounds of proficiency testing to provide continuous validation or refinement to your adjustments, can be continued.
