Medical Laboratory Science

Available at: Kingston


Medical Laboratory Technologists conduct sophisticated diagnostic tests on blood, body fluids and tissues to provide important information used in detecting illness and monitoring health. They enjoy rewarding careers where they use their skills to; measure chemical components in blood and body fluids, detect diseases in blood cells, perform blood typing and cross-matching for blood transfusion, detect and identify infections caused by bacteria and fungi, and prepare surgical and autopsy tissues for analysis. Medical Laboratory Technologists represent one of the largest groups of professionals in health care.

The final year of the program occurs inside the laboratories of partner hospitals and private institutions and is arranged by the College. Students are expected to finance clinical placement costs (tuition, travel, room and board). Start date and location for third year placement are determined by program and clinical site requirements. Locations may include: Kingston Health Sciences, Brockville General Hospital (rotations at Kingston Health Sciences), Quinte Healthcare (Belleville Site), Mount Sinai Hospital, LifeLabs (Belleville site, rotations at Quite Healthcare), EORLA (Eastern Ontario Regional Laboratory Association) Ottawa sites including: The Ottawa Hospitals (Civic, General and Riverside Campuses) with possible rotations at Children’s Hospital of Eastern Ontario (CHEO), The Montfort (Hospital), and Queensway Carleton Hospital, Sick Kids (Toronto), and Grand River/St. Mary’s Hospitals, Kitchener. 

Graduates are eligible to write the general certificate exams of the Canadian Society for Medical Laboratory Science. 

This program is not open to International students.
