About the Job

NOC: 3211
Occupation: Medical Laboratory Technologists
Category: Health Occupations

Nature Of Work:

Medical laboratory technologists (MLTs) play a pivotal role in health care. It has been estimated that 85 percent of medical diagnostic decisions are made on the basis of laboratory results.

MLTs collect and handle laboratory specimens, conduct complex laboratory tests and experiments/studies, analyze specimens, and interpret quality-control data to verify the accuracy and precision of test results for use by health-care practitioners in diagnosis, treatment, and prevention of disease.

General MLTs may specialize in one, or perform duties in all, of the following disciplines: Microbiology, Chemistry, Histology, Transfusion Science, and Haematology. General MLTs analyze blood, urine, and other body fluids (Chemistry); prepare tissue sections for detection of disease (Histology); differentiate blood cells and detect blood disorders/diseases (Haematology); perform blood group, type and compatibility tests for transfusion purposes (Transfusion Science); and identify and perform susceptibilities on a broad range of disease-causing (pathogenic) and opportunistic micro-organisms such as Staphylococcus aureus and Mycobacterium tuberculosis (Microbiology).

MLTs with subject certification perform duties in diagnostic cytology or Clinical Genetics. Cytotechnologist MLTs observe and detect changes in cells associated with cancer. Clinical Genetic MLTs perform tests on chromosomes, DNA, and RNA to allow detection of genetic diseases (specimens include body fluids and tissues).

All MLTs may be involved in research and development plus molecular testing. MLTs train and supervise other laboratory personnel such as MLT students, medical residents, registered nurses, and other health-care professionals.

Skills:

This work demands accuracy and close attention to detail. You must have good manual dexterity and be comfortable working with instruments and technology, including information technology. Good communication skills and the ability to work with various health professionals are important. Although teamwork is essential, an MLT must be self-sufficient and able to work independently, be capable of critical thinking, and exercise good judgement. You must be flexible, open to change, and willing to keep pace with rapid developments in the field.

Other Considerations:

Depending on the size and type of institution, people in these occupations may be required to work evenings, weekends, or holidays.
