Proficiency Testing: An Important Component of a Testing Laboratory’s Quality System
Left to their own devices, many testing laboratories would operate in relative isolation from other laboratories, missing opportunities to compare their data with others. The risks associated with that approach include flawed or bias data.
Proficiency testing provides an opportunity for a laboratory to compare its data with that of other laboratories and have an independent appraisal of the laboratory’s data compared to reference values or to the performance of other laboratories. The results from such participation provide laboratory managers with either a confirmation that the laboratory’s performance is satisfactory or an alert that investigation of potential problems within the laboratory is required.
When proficiency testing is an ongoing program, participation also provides laboratory management with continuous monitoring of the comparability of the laboratory’s data and of its continuing effectiveness in the relevant tests involved. If competent performance is demonstrated, this leads to a number of other potential benefits such as:
- Identifying testing problems;
- Comparing methods or procedures;
- Validating new methods;
- Comparing prep technicians or analysts capabilities;
- Improving the performance of a method, prep technician or analyst;
- Educating staff;
- Instilling confidence in staff, management and clients;
- Satisfying regulators and accreditation bodies.
Ask your testing laboratory how many proficiency tests and inter-laboratory studies they participated in last year, then ask about their scores.
