Final answer:
A lab technician would be most concerned with CLIA safety standards as they directly handle the processing and analysis of test samples in a medical laboratory.
Step-by-step explanation:
Among the health care workers mentioned, a lab technician would be most concerned with the safety standards established by the Clinical Laboratories Improvement Amendments, or CLIA. Medical or clinical laboratory technologists (such as Medical Technologists and Medical Laboratory Technicians) and phlebotomists are directly involved in the processing and analysis of bodily fluids in the laboratory setting. CLIA standards are critical to their work as they ensure the accuracy, reliability, and timeliness of test results regardless of where the test was performed. The education of these professionals varies, with Medical Technologists often holding a bachelor's degree and certification, while Medical Laboratory Technicians may have an associate degree. Both may be responsible for adhering to laboratory safety protocols, which are designed to protect them as well as patients, ensuring high-quality laboratory practices.
