From 1991 to the end of 2019 the PTC schemes were operated under the management of the Canadian Association for Laboratory Accreditation (CALA). At the end of 2019, the operation of these schemes was transferred from CALA to PTC.
What makes PTC different?
We provide personalised service that is unique to your needs. PTC provides four samples per round of testing, twice a year. Samples are not concentrated so they arrive ready for analysis. This reduces the chance of error and provides for more accurate test results. Reports are sent in a timely manner and contain all the information needed to maintain accreditation and if required, take corrective action.
Why is Proficiency Testing Important?
Proficiency Testing helps laboratories monitor the quality of their testing methods and procedures by providing all participants in the study with the ability to confidentially compare their results to each other. The detailed data helps laboratories identify problem areas, take corrective action and then verify results as part of their ongoing participation in proficiency testing and commitment to quality service.
