CMLA Quality Control & Assurance in Laboratory Practices

Question 1

Why is quality control important in laboratory testing?

Accepted Answer

To ensure accuracy and reliability of results.

Answer

Quality control is crucial in laboratory testing to ensure the accuracy and reliability of results. It involves a set of procedures designed to monitor the performance of analytical methods and equipment, identifying and correcting errors. This commitment to quality directly impacts patient diagnosis, treatment, and overall healthcare outcomes.

Question 2

What is the role of calibration in quality control?

Accepted Answer

To ensure equipment accuracy and precision.

Answer

Calibration plays a vital role in quality control by ensuring equipment accuracy and precision. It involves adjusting an instrument to provide measurements that are consistent with a known standard. Regular calibration guarantees that the equipment produces reliable and trustworthy results, which is essential for accurate diagnoses.

Question 3

What should be done if a quality control test result falls outside the acceptable range?

Accepted Answer

Investigate the cause and correct the problem.

Answer

If a quality control test result falls outside the acceptable range, it is imperative to investigate the cause and correct the problem before proceeding with patient testing. This indicates a potential issue with the equipment, reagents, or technique that could lead to inaccurate patient results. Addressing the problem ensures the reliability of all subsequent tests.

Question 4

How often should quality control tests be performed in a laboratory?

Accepted Answer

As specified by laboratory protocols or at each shift.

Answer

Quality control tests should be performed as specified by laboratory protocols or at each shift to ensure continuous monitoring of test performance. Regular QC checks help detect potential issues with equipment, reagents, or technique early on. This proactive approach maintains the reliability and accuracy of patient results over time.

Question 5

What should be done if quality control procedures reveal an equipment malfunction?

Accepted Answer

Stop using the equipment until it is repaired or recalibrated.

Answer

If quality control procedures reveal an equipment malfunction, it is critical to stop using the equipment until it is repaired or recalibrated. Continuing to use faulty equipment would compromise the accuracy and reliability of patient test results. This action ensures patient safety and maintains the integrity of the laboratory's diagnostic services.
