Medical Laboratory Technology
Question Bank
Course Introduction
Medical Laboratory Technology introduces students to the essential principles and practices involved in the clinical laboratory setting. The course covers the fundamental techniques of specimen collection, handling, and analysis across various laboratory disciplines such as hematology, microbiology, clinical chemistry, immunology, and blood banking. Emphasis is placed on the operation and maintenance of laboratory equipment, adherence to quality control standards, and the critical role laboratories play in the diagnosis, treatment, and prevention of disease. Students also explore laboratory safety, professional ethics, and data management, preparing them for roles within healthcare teams and further studies in medical laboratory science.
