Final answer:
The correct answer is 'Quality assurance', which ensures test result accuracy by monitoring test procedures in the medical office.
Step-by-step explanation:
The correct answer to the question is b. Quality assurance.
Quality assurance is the process of implementing measures to ensure that the test procedures performed in a medical office are accurate and reliable. It involves monitoring and evaluating the entire testing process to identify and address any potential errors or deviations in the procedures.
Quality control, on the other hand, focuses on monitoring the test results themselves to ensure their accuracy and reliability. Quality improvement involves making changes to improve the overall quality of the testing process. Peer review, as mentioned in the reference question, refers to the formal process through which scientific research is checked for originality, significance, and quality before being accepted into scientific literature, and is not specifically related to test procedures in a medical office.
