Course Description

Introduces pathophysiology, diagnosis, and monitoring of select human diseases on an organ system basis. Includes: enzymology, acid-base balance, lipid metabolism, liver and cardiac pathophysiology, and protein metabolism. Acceptance into the second year of the MLT Program required. Audit available.

Addendum to Course Description

The course presents a study of clinical enzymology including test methodologies and disease correlation, focusing primarily on interpretation of enzyme data and organ system panels. Principles and applications of blood gas analysis and lipid metabolism will be presented including test methodologies, interpretation of test results, and correlation of test results with various diseases and abnormal conditions.

Intended Outcomes for the course

Upon successful completion students should able to:
 
1. Use an understanding of normal and abnormal test results for enzymes, acid-base balance, and lipids and their correlation with appropriate pathologic conditions to make appropriate and effective on-the-job professional decisions.
2. Apply appropriate laboratory techniques, methodologies, instruments and equipment in the performance of blood gas analysis, and enzyme and lipid testing to affect quality patient care.
3. Adapt laboratory techniques and procedures in a corrective manner when errors and discrepancies in results are obtained to affect resolution in a professional and timely manner.

Course Activities and Design

The material in this course will be presented in a traditional classroom (Campus program), or distance-learning format (Distance learning program). Both traditional and distance learning sections include required laboratory activities. Traditional classroom instruction consists of lecture, discussion, web based instructional media (tutorials, animations, videos, etc.) and other educationally sound practices. Distance learning sections include similar educational practices and are primarily presented in a web based format. Both campus and distance learning sections require periodic campus based laboratory exercises. In addition, the distance learning section may have hospital based laboratory exercises. A laboratory manual will be provided. The laboratory exercises provide an opportunity for students to employ the testing principles and methodologies discussed and 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.

Outcome Assessment Strategies

The instructor will outline the methods used to evaluate student progress and the criteria for assigning a grade at the beginning of the course. Assessment methods may include written and practical examinations and laboratory write-ups. Evaluation of problem solving skills, teamwork, attendance, laboratory performance and communication skills may also be included.
