Medical laboratory sciences (MLS) is a health care profession with special expertise in laboratory medicine.
Medical laboratory scientists, sometimes referred to as medical technologists (MT) or medical laboratory technicians (MLT), are vital members of the health care team who play a central role in the detection, diagnosis and treatment of disease. To accomplish this, medical laboratory scientists must have a thorough understanding of a wide range of subjects including hematology, clinical chemistry, immunohematology (transfusion medicine), clinical microbiology, and immunology. Laboratory scientists appreciate investigative work and problem solving and are counted on to provide physicians with information critical to the successful diagnosis and treatment of patients. Medical laboratory scientists and technicians are employed by hospitals, clinics, research facilities, universities, and in lab-related commercial industry.
