How can you use proficiency testing to improve laboratory performance?

1 Choose a suitable PT provider

The first step is to choose a PT provider that offers relevant programs for your laboratory scope and tests. You should consider the frequency, format, cost, and feedback of the PT programs, as well as the reputation and accreditation of the provider. You can consult with your peers, accreditation bodies, or professional associations to find a suitable PT provider for your needs.

2 Enroll in the PT programs

The next step is to enroll in the PT programs that match your laboratory tests and methods. You should follow the instructions and deadlines of the provider and ensure that you have enough resources and staff to participate in the PT programs. You should also inform your staff about the objectives and expectations of the PT programs and assign responsibilities for handling and testing the PT samples.

3 Test the PT samples

The third step is to test the PT samples using the same methods, equipment, and personnel that you use for your routine samples. You should treat the PT samples as if they were real patient samples and follow your standard operating procedures and quality control measures. You should not modify or repeat the tests unless you have a valid reason and document it.

4 Report the PT results

The fourth step is to report the PT results to the provider according to their specifications and deadlines. You should use the same units, formats, and reporting systems that you use for your routine samples. You should not communicate or compare your results with other laboratories before receiving the PT feedback.

5 Review the PT feedback

The fifth step is to review the PT feedback that the provider sends you after analyzing and comparing your results with those of other laboratories. The PT feedback usually includes your performance score, the acceptable range, the peer group statistics, and the comments and recommendations of the provider. You should check the accuracy and completeness of the feedback and contact the provider if you have any questions or concerns.

6 Implement corrective actions

The final step is to implement corrective actions if your PT results are unsatisfactory or inconsistent with your expectations. You should investigate the possible causes of error, such as method, equipment, reagent, or staff issues, and take appropriate measures to prevent them from recurring. You should also document and monitor the corrective actions and evaluate their effectiveness in the next PT cycle.
