FAQs

Quality assurance audits should be conducted at least annually, with more frequent internal audits recommended. Additional audits may be necessary for new method validations or in response to significant changes in laboratory operations.

The audit should be performed by qualified quality assurance specialists, experienced laboratory auditors, or accreditation body representatives with expertise in environmental testing methods and relevant regulatory standards.

The checklist covers sample receipt and handling, analytical method validation, instrument calibration and maintenance, quality control procedures, data management and security, proficiency testing participation, and documentation practices.

By providing a comprehensive evaluation of laboratory practices, the checklist helps identify potential sources of error, ensures adherence to standard methods, and promotes continuous improvement in the quality and reliability of environmental testing services.

Audit findings should be documented in a detailed report, shared with laboratory management, used to develop corrective action plans for any identified deficiencies, and incorporated into ongoing quality improvement initiatives.
