Portland Community College | Portland, Oregon

This survey course provides an introduction into the field of clinical laboratory science. The role of medical laboratory sciences will be presented in the context of providing quality patient health care.

Upon successful completion of the course students should be able to:

1. Recognize the role of medical laboratory technology in the context of providing quality
2. Discuss the medical laboratory technology profession, career and professional development opportunities.
3. Describe the basic areas of study within the clinical laboratory and how these areas aid in the diagnosis of disease, including: clinical chemistry, immunology, immunohematology, urinalysis & body fluid, microbiology, and hematology.
4. Demonstrate basic clinical laboratory procedures using appropriate laboratory techniques and instrumentation in accordance with current laboratory safety protocols.
5. Calculate, interpret, and report laboratory results in accordance with laboratory protocols.
6. Demonstrate effective written and verbal communication that represents competence and professionalism in the clinical laboratory setting.

The class will be presented by means of lecture/discussion, audio-visual presentations, handouts, demonstrations, web based instructional media, lab exercises and other educational practices. Laboratory exercises will provide an opportunity for students to employ the testing principles and methodologies introduced and will allow for discussion, application and correlation of the concepts presented.  The student is expected to perform all laboratory procedures according to the criteria established by the department.  The course grade will be based on participation and submission of assignments.

At the beginning of the course, the instructor will outline the methods used to evaluate student progress and the criteria for assigning a grade. Assessment methods may include written homework assignments,  discussion and lab activities, and attendance.
