Overview
What Does a Medical Laboratory Scientist Do?
Medical Laboratory Scientists (MLS), also known as Clinical Laboratory Scientists, are healthcare professionals who perform complex laboratory analyses that are essential for diagnosing diseases, monitoring treatment effectiveness, and assessing overall patient health. Working behind the scenes in clinical laboratories, you'll analyze biological specimens such as blood, urine, and other body fluids using sophisticated equipment and techniques across multiple disciplines including chemistry, hematology, microbiology, immunology, and molecular biology. This career is ideal if you have a strong interest in science and research and prefer a work environment with minimal direct patient interaction while still making a significant impact on patient care.
