What is the function of external quality assessment programs?

The function of external quality assessment programs is primarily to provide proficiency surveys and lab inspections. These programs are designed to assess the accuracy and reliability of laboratory test results by comparing them against standardized benchmarks. This process ensures that laboratories maintain high-quality standards and comply with regulatory requirements.

By participating in proficiency surveys, laboratories receive samples to test and report results, which are then evaluated to verify the accuracy of their testing methods. This allows labs to identify any potential issues in their testing processes and implement corrective actions as needed. Additionally, lab inspections help ensure compliance with safety regulations, quality control measures, and operational standards, which are critical for maintaining overall laboratory performance and credibility.

This focus on proficiency and inspection aligns with the broader goals of improving laboratory quality and reliability, thereby supporting better health outcomes for patients indirectly through improved laboratory accuracy and trustworthiness.
