Question 65

Verifying date of expiration is essential when performing quality control for CLIA waived testing.

Ensuring that the reagents and materials used in testing are within their expiration date is crucial for maintaining the integrity and accuracy of the test results in CLIA waived testing.

A) Ensuring the sterility of the testing medium

While ensuring sterility is important in laboratory settings, it is not specifically highlighted as a critical requirement for quality control in CLIA waived testing. The focus of quality control in this context is more on the validity of the reagents and their expiration rather than sterility alone.

B) Transporting specimens

Transporting specimens is a procedural step that is important for maintaining sample integrity, but it does not directly relate to the quality control measures required for CLIA waived testing. Quality control is more concerned with the validity of the tests themselves rather than the logistics of specimen handling.

C) Confirming the requisition order

Confirming the requisition order is a necessary administrative step but does not play a direct role in the quality control process for CLIA waived testing. Quality control focuses on ensuring that the tests performed are accurate and reliable, which is not addressed by merely confirming orders.

D) Verifying date of expiration

Verifying the date of expiration is essential as it ensures that all reagents and testing materials are still effective and reliable. Using expired materials can lead to inaccurate test results, making this step critical for maintaining quality control in CLIA waived testing.

Conclusion

Verifying the date of expiration is a fundamental aspect of quality control for CLIA waived testing as it directly impacts the reliability of test results. Other options, while important in different contexts, do not address the specific requirements for ensuring the accuracy of CLIA waived tests, making option D the definitive correct choice.
