This white paper, by LGC Proficiency Testing expert Heather Jordan, is designed to assist organisations in deciding whether to pursue internally organised or externally provided proficiency testing, by comparing the benefits and required resources for each.

Download to understand these key considerations:

- the benefits of an internally run PT program compared to those of an independent, external PT program;
- the financial implications of conducting PT programs internally compared to participating in an external PT scheme;
- the necessary requirements for an internally managed PT program to provide a laboratory with the same level of confidence in the validity of their measurements as can be provided an external PT scheme;
- the ways in which an internal PT program should be assessed by a third party to ensure that it is being competently managed and organised.

This white paper will equip you with the knowledge you need to ensure that your PT scheme is operating within the scope if ISO/IEC 17025, and that your analytical testing is valid.
