What is an MLT?

Medical Laboratory Technologists (MLTs) are health professionals who perform laboratory analyses and provide information to physicians. They help physicians to diagnose and treat patients, as well as monitor and prevent disease.

Medical Laboratory Technologists operate a variety of complicated instruments. They must have good motor skills, hand-eye coordination and manual dexterity. In addition to technical skills, they must have a strong attention to detail in order to detect subtle change to the microscopic appearance of blood, tissue and bacterial cells. MLTs must also determine the validity of the results they obtain, which requires analytical and critical thinking. MLTs work in an ever-evolving environment, and on occasion need to design new procedures to reflect the rapid pace of change in their workplace. Whether working alone or as a member of a team, the MLT must be able to manage time efficiently and communicate clearly.

Is Medical Laboratory Technology a Career for me?

Medical laboratory technology is a constantly evolving and rewarding career. Within the past 10 year new discoveries have advanced scientific knowledge, the Technologist’s role will continue to change and expand.


Medical Laboratory Technologists perform a variety of different tests and have a wide range of career options. Every day brings a different challenge and new problems to solve.  

Job Satisfaction

Test results have an immediate impact on the care of critically ill patients. Making a real difference in patients’ lives contributes to high levels of job satisfaction among Medical Laboratory Technologists.  


Medical Laboratory Technologists often work independently with minimal supervision. While still a key member of the health care team, MLTs have greater control over their daily routine than many other health care professionals.

MLTs may be certified in the following 3 categories:

MLT - General

Medical laboratory technology - General programs include courses in clinical chemistry, clinical microbiology, hematology, histology and transfusion science  

MLT - Cytology

Diagnostic Cytology Conducts tests on cells, fluid and tissues taken from the body to detect cancer Note: Diagnostic Cytology Certification since June 2017 includes Histology equivalent to MLT General

MLT - Clinical Genetics

Conduct tests to analyze and diagnose abnormalities in chromosomes and DNA.
