What does performing quality control testing ensure?

1. Accuracy of test results

2. Speed of test completion

3. Cost-effectiveness of supplies

4. Maintenance of equipment

The correct answer is: Accuracy of test results

Performing quality control testing is essential in clinical settings as it primarily ensures the accuracy of test results. Quality control processes involve routinely checking the performance of laboratory tests against established standards. This includes using control samples to verify that the test methods are functioning correctly and are yielding reliable results. Accurate test results are critical for proper patient diagnosis, treatment decisions, and overall patient safety. By demonstrating that the testing process is reliable, quality control testing builds confidence in the results delivered by the lab. While other factors, such as the speed of test completion, cost-effectiveness of supplies, and maintenance of equipment, are important in a healthcare setting, they do not fundamentally pertain to the core purpose of quality control testing, which is to validate and ensure that the test results provided are accurate. Therefore, the emphasis of quality control testing lies in the integrity of results, making it indispensable in the medical field.
