Medical Laboratory Technology
Mock Exam
Course Introduction
Medical Laboratory Technology is a comprehensive course that introduces students to the fundamental theories and practical skills required for diagnosing diseases through laboratory analysis. The course covers essential topics such as clinical biochemistry, microbiology, hematology, immunology, and pathology, emphasizing both manual and automated techniques for specimen collection, processing, and analysis. Students will learn about laboratory safety protocols, quality control, and the interpretation of laboratory results, gaining hands-on experience with modern diagnostic equipment. By the end of the course, students will be equipped with the knowledge and competencies necessary to support healthcare teams in the accurate identification and monitoring of medical conditions.
