ISO 20776-3 Quality Control for Antimicrobial Susceptibility Testing

The ISO 20776-3 standard provides a comprehensive framework for quality control in antimicrobial susceptibility testing (AST), which is critical for ensuring reliable and accurate results. This service focuses on the implementation, monitoring, and validation of AST procedures to meet the highest regulatory standards.

Antimicrobial resistance (AMR) poses a significant threat to public health globally. The development of resistant bacteria can lead to treatment failures and increased morbidity and mortality rates. By adhering to ISO 20776-3, laboratories can ensure that their AST results are robust and reliable, thereby contributing to the global effort in combating AMR.

The standard mandates a series of quality control measures designed to minimize errors and ensure consistency across different testing methods. These include proficiency testing schemes, internal quality controls, and the use of standardized reference strains. The implementation of these practices not only enhances the accuracy of AST but also ensures that results are comparable with those from other laboratories.

ISO 20776-3 emphasizes the importance of traceability in AST. This means that all test results should be linked to a specific batch and method, ensuring that any discrepancies can be traced back to their source. The standard also requires regular calibration and validation of equipment used in AST, which is crucial for maintaining high-quality standards.

Another key aspect of ISO 20776-3 is the establishment of robust quality management systems (QMS). These systems help laboratories maintain consistency in their testing processes, ensuring that results are reliable and reproducible. QMS also facilitates continuous improvement by identifying areas where performance can be enhanced or errors minimized.

The standard includes detailed guidelines on how to handle critical factors such as specimen preparation, inoculation methods, incubation times, and interpretation of results. Each step is designed to minimize the risk of error, ensuring that the final results are accurate and reliable. This level of detail is particularly important in AST, where even small variations can lead to significant discrepancies.

ISO 20776-3 also addresses the issue of proficiency testing (PT). PT schemes are used to evaluate the performance of laboratories by comparing their results with those from other participating laboratories. This ensures that all laboratories involved in AST are meeting the same standards and provides a benchmark for continuous improvement.
