Medical Laboratory Science

Medical Laboratory Scientists (also known as Clinical Laboratory Scientists or Medical Technologists) are highly skilled laboratory scientists who perform and evaluate laboratory procedures using a variety of sophisticated instruments. They perform, supervise and provide consultation for laboratory analyses on blood and various body fluids to obtain data from which a diagnosis is made and appropriate therapy initiated. The major disciplines in laboratory science are:

  • Hematology
  • Immunohematology (blood banking)
  • Microbiology
  • Immunology
  • Urinalysis
  • Mycology
  • Parasitology

An individual may specialize in one of these disciplines or remain a generalist, depending on the type of laboratory and the needs of the facility in which they are employed. A career in medical laboratory science provides opportunities for work that are both personally rewarding and challenging.

As cost consciousness in health care delivery has increased, Medical Laboratory Scientists have become increasingly valuable to the health care system. This is because Medical Laboratory Scientists are knowledgeable about cost effective ways to deliver quality care and are trained to make the kinds of decisions that make effective lab services possible. Medical Laboratory Scientists assume positions of increasing responsibility in clinical laboratories and within institution management structure. Their functions include managing the laboratory and directing the work of others performing complex laboratory analyses and making judgments about the quality of laboratory results before they are reported. Medical Laboratory Scientists must be experts in clinical laboratory science as well as in the administrative and managerial functions necessary to ensure the effective operation of clinical laboratory services.

Minimum requirements for becoming a medical laboratory scientist includes satisfactory completion of two years of pre-professional college work, including certain prescribed courses. Students may then be admitted to a two-year professional program approved the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS). High school students can prepare for a career in Medical Laboratory Science by taking courses in physical and biological sciences, along with other college preparatory courses.

For admission to the Bachelor of Science in Medical Laboratory Science degree programs or the Master of Science in Clinical Laboratory Science at the University of Tennessee Health Science Center (UTHSC), students are expected to be able to successfully meet the Technical Standards outlined below. Students are required to sign the Technical Standards Commitment form indicating their understanding and ability to meet these standards either with or without accommodations (for persons with documented disabilities). Any questions about these technical standards should be directed to the program director of the MLS programs.

 UTHSC receives applications from a diverse body of potential students including those with disabilities. Reasonable accommodations will be provided to help students meet these technical standards when appropriate, in accordance with the Americans with Disabilities Act (ADA). Any student wishing accommodations should contact the Student Academic Support Services and Inclusion (SASSI) for further information. Information regarding accommodations can be found on the Disability Services page.

 In the event a student cannot fulfill these Technical Standards with or without reasonable accommodations at any time in their program, the student will be ineligible for admission or continued enrollment in the program. In addition to ensuring that students can meet the intellectual, emotion and physical criteria for medical laboratory science, it should also be noted that of utmost importance is the student's ability to provide for the welfare and safety of their patients and others. This is the foundation of all Technical Standards and if this cannot be done, the student is unable to meet the criteria outlined by the Technical Standards.

Once enrolled in the BS MLS or MS CLS Program, students must meet the requirements of the curriculum, including the demonstration of the skills described herein for the Program in order to progress through the curriculum and to graduate.
