Final answer:
A Certified Medical Assistant cannot perform a CBC test with a point-of-care testing device as it requires equipment like a laboratory centrifuge and analysis by a licensed laboratory technician.
Step-by-step explanation:
A CMA (Certified Medical Assistant) cannot perform a CBC (Complete Blood Count) test with a point-of-care testing device. CMAs are trained to carry out a variety of tasks in the medical office, including administrative and clinical duties. However, when it comes to laboratory tests like a CBC, which require detailed analysis and use of a laboratory centrifuge and other specialized equipment, these are typically conducted by a licensed laboratory technician or a phlebotomist. The CMA may draw the blood and prepare the sample, but the actual testing and analysis are beyond their scope of practice.
