Being an important part of quality assurance, proficiency testing measures the analytical performance of laboratories. This enables you to compare and monitor your performance against other laboratories, and demonstrate your precision of analysis to involved parties.

Proficiency testing (PT; similar to inter-laboratory comparison or ring trial) is a measure to ensure that your laboratory produces accurate results. Regular participation in proficiency testing programs is required for laboratories that want to comply with international standards such as ISO/IEC 17025. Trilogy Analytical Laboratories in the Netherlands and India offers laboratories the possibility to participate in proficiency tests.

As a PT provider, Trilogy Europe, designs and manages all aspects of their PT schemes. Listed below are the PT schemes available for 2019.
