What documentation should be retained for QA/QC records and for how long?

• A. Retention of calibration records only is required.
• B. Calibration records, MQC results, method validation, instrument maintenance, and training records; retention typically governed by policy or regulatory requirements (years).
• C. QA/QC documents should be kept indefinitely.
• D. Retention is determined by lab size and is not standardized.

Answer: (B)

Retention of QA/QC records is driven by policy and regulatory requirements, not by lab size or a vague rule. A solid approach is to keep a comprehensive set of documentation that demonstrates quality and traceability over time: calibration records to prove instrument accuracy and traceability; MQC results to show ongoing control and performance; method validation to confirm that procedures work for their intended use; instrument maintenance to document service, repairs, and reliability; and training records to verify that personnel are competent to perform the work. The length of time you keep these records should follow your organization’s policy and any applicable regulations or accreditation standards, which typically specify a multi-year retention period or retention for the life of the instrument plus an established window for audits. This combination ensures the data remains available for quality reviews, investigations, and compliance checks.
