Estimated Completion Time

16 - 18 weeks


Have you ever wondered how a health professional knows how to diagnose an illness? Or what medications to prescribe to a patient depending on the person’s body and their signs and symptoms? Learn about different diagnostic technology used and essential body systems and fluids that need to be understood to make an accurate diagnosis of a disease, condition, or illness. This career field is flourishing, and now is the time to be part of it!

During this course, you will learn career-related skills and earn a badge for this accomplishment. A badge is a digital certification of your career-related learning that you can share on social media or with higher education platforms, colleges, potential employers, peers, and colleagues.
