Which item is NOT listed as a key component of a Quality Assurance program?

• A. Instrument and equipment maintenance
• B. Calibration
• C. Proficiency Testing
• D. SOP documentation

Answer: (B)

Quality Assurance focuses on the systems and processes that ensure work is performed consistently and producing reliable results. Things like having documented procedures (SOP documentation), keeping instruments and equipment well maintained, and participating in proficiency testing are all core QA elements because they shape how work is planned, controlled, and validated across the lab. Calibration, while essential to ensure measurement accuracy, is typically viewed as a quality control or instrument-management activity rather than a QA component. It’s the technical step that verifies an instrument’s readings against known standards, directly ensuring accuracy of results but not defining the overall process controls that QA establishes. In the framework implied by this question, calibration isn’t listed as a key QA component, which is why it’s the best choice for the item not included. The other options—SOP documentation, instrument/equipment maintenance, and proficiency testing—are standard QA elements because they underpin documented procedures, ongoing operation reliability, and external performance assessment.
