A QC plan for a new method should include which items?

• A. Marketing strategy and public relations plan
• B. Control materials, target ranges, frequency, acceptance criteria, EQA, documentation
• C. Patient consent and privacy forms
• D. Inventory of non-lab staff training

Answer: (B)

A QC plan for a new method focuses on ensuring that the method’s results are reliable and traceable over time. The essential elements are control materials to verify ongoing accuracy, target ranges or control limits to define what counts as acceptable results, the frequency of QC checks to know when to run controls, acceptance criteria that specify when a result passes or fails, participation in external quality assessment to compare performance with other laboratories, and thorough documentation to record control results, investigations, and corrective actions. Control materials provide a consistent benchmark to detect shifts or biases; target ranges define the tolerance for results; frequency determines how often you monitor performance; acceptance criteria establish the decision thresholds for action; EQA offers external validation of performance; and documentation ensures traceability and compliance with quality systems. Other options don’t fit because marketing plans, patient consent/privacy forms, and non-lab staff training inventories are not part of monitoring and assuring the analytical method’s performance.
