Last Date of Approval: Spring 2022
Total Lecture Hours: 30
Total Lab Hours: 0
Total Clinical Hours: 0
Total Work-Based Experience Hours: 0
Common human parasites, their morphology, life cycles, symptomology, and techniques of identification are covered. Competencies in mycology include studying the changing etiologic role of fungi, knowledge of proper specimen collection, processing, and culture methods. This course will help students gain scientific literacy vital to making important life decisions. The course is designed to help students develop the hands-on and critical thinking skills needed to function as an entry-level medical laboratory technician and satisfies curriculum requirements of the National Accrediting Agency for Clinical Laboratory Sciences.
