Medical Laboratory Technology | Tyler Junior College

Medical Laboratory Technology

Medical Laboratory Technology is a profession which combines the challenges and rewards of both medicine and science. Medical Laboratory Technicians perform a wide variety of laboratory procedures and work in both public and private laboratories serving the health care sector.

Medical and clinical laboratory technicians specialize in work to determine the presence, extent or absence of disease. They do this by performing a full range of routine laboratory procedures from simple blood screens to more complex tests to detect diseases such as cancer, coronary artery disease, and diabetes.

The Registered Medical Laboratory Technician is an allied health professional who is qualified by academic and practical training to provide service in medical and clinical laboratory science.
