Career Outlook

Medical laboratory science professionals, often called medical laboratorians, are vital healthcare detectives, uncovering and providing laboratory information from laboratory analyses that assist physicians in patient diagnosis and treatment, as well as in disease monitoring or prevention (maintenance of health). We use sophisticated biomedical instrumentation and technology, computers, and methods requiring manual dexterity to perform laboratory testing on blood and body fluids. Laboratory testing encompasses such disciplines as clinical chemistry, hematology, immunology, immunohematology, microbiology, and molecular biology. Medical laboratory science professionals generate accurate laboratory data that are needed to aid in detecting cancer, heart attacks, diabetes, infectious mononucleosis, and identification of bacteria or viruses that cause infections, as well as in detecting drugs of abuse. In addition, we monitor testing quality and consult with other members of the healthcare team.


The medical laboratory science profession has more than one career track based on level of education: medical laboratory technician (2 years) and medical laboratory scientist (4 to 5 years). Medical laboratory technicians are competent in the collection, processing and analysis of biological specimens, the performance of lab procedures, themaintenance of instruments, and relating lab findings to common diseases/conditions. Medical laboratory scientists have a more extensive theoretical knowledge base. Therefore they not only perform laboratory procedures including very sophisticated analyses, but also evaluate/interpret the results, integrate data, problem solve, consult, conduct research and develop new test methods.

  Essential Functions

In order to participate in a medical laboratory science educational program, students must be able to comply with program-designated essential functions, or request reasonable accommodations to execute these essential functions. Requirements include a sound intellect; good motor skills: eye-hand coordination and dexterity; effective communication skills; visual acuity to perform macroscopic and microscopic analyses, or read procedures, graphs, etc.; professional skills such as the ability to work independently, manage time efficiently, to comprehend, analyze and synthesize variousmaterials, as well as to hold sound psychological health and stability. 



Educational Requirements
A solid foundation in high school biology, chemistry, and math usually provides the groundwork for medical laboratory science education. A career as a medical laboratory technician requires completion of either an associate degree program integrating general education, science and medical laboratory science courses; or, a shorter certificate program that focuses on technical courses. The medical laboratory technician curriculum addresses the theoretical and practical aspects of each of the major laboratory disciplines.


Medical laboratory scientists complete a baccalaureate degree program that includes more in depth courses than the technician classes, as well as management and education courses. Such courses may be offered through a hospital-based program thatprovides the senior year for students from affiliated universities. An integrated university based program provides professional coursework prior to a shorter clinical experience, e.g. 5 to 6 months. Such a program usually is found in a major university or academic medical center. College science graduates who meet a program's prerequisites are also eligible to apply to a medical laboratory science program.


Accreditation of medical laboratory science or technician programs by the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) ensures that the programs maintain high educational standards (visit www.naacls.org for a list of accredited programs and contact information). Masters and doctoral programs are also available in medical laboratory science for those who wish to further their education.

MLT to MLS Articulation
Articulation in education refers to any arrangement used by colleges and universities to coordinate the curriculum of their program that will facilitate the transfer of credits so that students can move from one level to another and decrease the time needed to earn the next level of degree.

Individuals who have graduated from a NAACLS-accredited Clinical Laboratory Technician/Medical Laboratory Technician (CLT/MLT) program may be eligible, in some programs, to obtain a bachelor's degree in Clinical Laboratory Science/Medical Technology (CLS/MT) without repeating courses common to both degrees. In addition, portions of the clinical practicum may be waived in those areas in which you are proficient. Typically the program director/advisor will work with you to individualize your program of instruction based on your educational, clinical and/or work experiences.

There are many articulated programs across the nation which offer opportunities to individuals with an Associate Degree in CLT/MLT to complete their BS degrees and become certified as a Medical Laboratory Scientist. These programs are either on campus programs or have online offerings. The requirements for articulation vary by program (e.g. - some may require experience as a CLT/MLT or certification as a CLT/MLT and others may not) so it is important to check with individual institutions for their requirements.



Job Outlook/Salaries
The Bureau of Labor Statistics of the U.S. Department of Labor projects that the employment of medical laboratory technicians and scientists will increase by 14% through the year 2016. According to Jobs Rated Almanac, medical laboratory science has 25% job growth and good job security. Among health related professions, it currentlyranks #3. In 2008, the median salary for medical laboratory technicians was about $38,400, and $47,840 annually for medical laboratory scientists, based on geographic location. Currently there is a shortage in many parts of the country guaranteeing employment and higher salaries for graduates.

New MS Meets Clinical Lab Demand

Dominican University of California will launch a master’s program in Clinical Laboratory Science (CLS) with an emphasis in Molecular Diagnostics in fall 2013. The program, which will be the only CLS master’s program in California, comes at a time when demand for trained clinical laboratory scientists is growing both in California and throughout the United States.


NMU science department works to fill job openings

MARQUETTE -- Northern Michigan University's Clinical Science Department is holding workshops for high school teachers and professionals in the field.

Thursday was the first of the two workshops. The workshops address the basics of DNA and advancements made in disease diagnosis. NMU's Clinical Science Department is in elite company nationwide in terms of offering nationally-accredited programs.
