PT program overview

Introduction

Supelco is a global proficiency testing (PT) provider that manufactures best-in-class food, clinical, environmental and pharmaceutical PT products. The PT portfolio allows our customers in many different market segments to assess performance of laboratory employees and instrument and control the accuracy and precision of methods. The Supelco PT portal offers significant performance data to monitor and prove competency to customers and accreditation bodies. We have a vast portfolio of environmental PT schemes with "fit-for-purpose" samples to help you meet the needs of the laboratory.

Our proficiency testing (PT) program is a benchmark to:

  • provide staff with an insight into their laboratory′s performance, to verify the accuracy and reliability of their testing process
  • provide a comparison of performance with that of other laboratories, nationally and internationally
  • test and educate staff, provide a better understanding of the impact of incorrect results and identify areas where there may be problems
  • provide an independent evaluation of laboratory performance
  • demonstrate to clients, colleagues and accreditation bodies that there is a commitment to quality
