Medical Laboratory Technologists (MLT)

Medical Laboratory Technologists (MLTs) are an important part of the health care professional team. Using a variety of complex instruments, they analyze tissue samples, blood and other body fluids as a part of the diagnostic procedure. MLTs provide the results of these sophisticated tests to physicians, allowing them to make accurate diagnosis and if needed, appropriate treatment.
