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 varied 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 Disability Services for further information. Information regarding accommodations can be found on the Disability Services web page or email Keri Snyder.

 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.

Professionalism Policy

Students are expected to demonstrate professional behavior as a required element of all courses, including but not limited to, classes, clinical experiences, small group and team-based learning sessions, labs, other didactics, and simulation sessions. This policy details the procedures for reporting professional behaviors not satisfactorily addressed after intervention at the programmatic level.

Potential lapses in professionalism may be reported by faculty, staff, preceptors, or other students. The “Professionalism Policy Reporting Form” should be completed by the reporter and submitted via email to the Dean of Student Affairs in the College of Health Professions (CoHP). The Dean of Student Affairs, in consultation with the Director of Student Affairs for the CoHP, and the Office of Student Conduct, will review the report and determine if it is a professionalism concern (rather than Code of Conduct or Honor Code Violation). If the Dean of Student Affairs and/or the Director of Student Affairs is a reporter of a concern, the Dean of CoHP will designate someone else to review the report. For concerns involving student speech, the Office of General Counsel also will be consulted before any action is taken by anyone in the College. If the concern is determined to be an actionable professionalism concern by the Dean of Student Affairs and the Director of Student Affairs or designee(s) (rather than a Code of Conduct or Honor Code Violation), the steps outlined below will be followed.

All verifiable reports of professionalism concerns will result in a meeting with the student, relevant program director (PD) or chair, and Dean of Student Affairs or Director of Student Affairs or designee. The student will have the opportunity to respond to and provide information regarding the reported concern during this meeting. A completed notification document will be signed by all parties immediately following the meeting. If the concern is determined to not be actionable upon this review and discussion, then the Dean of Student Affairs and/or Director of Student Affairs or designee will not move the process forward beyond this meeting.

Following the meeting, the Dean of Student Affairs or Director of Student Affairs and PD or chair (or a designee for any of these positions if the individual in the position is the one who reported the concern) will decide if the concern is major and if it should be elevated to the program’s Progress and Promotions (P and P) committee. If so, the program’s P and P committee will review the complaint and make recommendations (following the CoHP policy 112), under the guidance of the Dean of Student Affairs or designee. The first major lapse in professionalism typically will result in the program’s P and P committee placing the student on probation. Failing to meet the terms of the probationary plan and/or a second major lapse may result in dismissal of the student from the program. The student will have the opportunity to appeal the dismissal to the Dean of CoHP before it is final.

Generally, a student in CoHP is expected to demonstrate satisfactory personal, professional, and ethical behavior deemed by faculty and the relevant professions as being necessary for academic success and competency in clinical practice. Such areas may include but are not limited to the ability to establish rapport with clients, appropriate communication, ability to demonstrate respect and empathy, ability to work effectively with members of the health care team, dependability, judgment, integrity, initiative, and interest.

Examples of minor concerns may include, but are not limited to:

  • not responding to emails from faculty/staff in a timely fashion
  • tardiness
  • turning assignments in late
  • unexcused absence
  • lack of receptive attitude towards constructive feedback
  • not complying with dress code policy (see below)

Examples of major lapses may include, but are not limited to:

  • more than 1 minor concern
  • absence from a required session without appropriate notifications
  • disrespectful communication
  • not acknowledging authority or chain of command
  • lying
  • HIPAA violation
  • endangering patients
  • inability to work effectively with members of a health care team
  • biased behavior (e.g., making negative judgments or assumptions about others based on weight, appearance, socioeconomic status, language, religion, education level)

COHP Dress Code Policy:

All individuals are expected to:

  • wear ID badges
  • maintain appropriate personal hygiene (e.g., minimize body odor, keep hair and facial hair clean, minimize smoke/perfume/cologne odor)
  • keep clothing clean, neat, and appropriate for the program activity
  • wear shoes that are safe, clean, and in good repair
  • not let hair, facial hair, jewelry, or other accessories interfere with safety or activities
