Clinical laboratory scientists do a lot more than measure blood sugar. They conduct more than 2,000 tests, and 70 percent of the objective information used in diagnosing cases comes from the laboratory, according to Kathy Hansen, director of laboratory operations at the University of Minnesota Medical Center, Fairview.
A clinical laboratory scientist, or CLS, may work in general areas such as hematology, chemistry, microbiology or blood banking, specialize in molecular-based testing for genetic and infectious diseases, or test for viral diseases. A CLS may also supervise point-of-care testing done at bedside by non-laboratory staff.
"The clinical laboratory scientist is really responsible for the total testing process, from the time that test is ordered and those results are interpreted," said Carol McCoy, program director of the clinical laboratory science program for Fairview Health Services.
"I call us the unsung heroes," adds Priscilla Cherry, president of laboratory services for Fairview. "We're just kind of in the background."
The profession may soon become more prominent by its scarcity. A large group of CLSs is expected to retire soon, leading to a national shortage, Cherry said.
Students who are considering a career as a CLS should have a bachelor's degree from an accredited CLS program. Coursework is similar to pre-med or pre-dentistry, with chemistry, organic and biochemistry, biology, physiology, genetics, microbiology, immunology and statistics. There's a practical component as well, teaching students how to conduct tests and interpret results.
"Once they graduate, they're ready to go," said McCoy. "There is very little orientation by the employer."
CLS degree programs aren't well known among prospective students. Institutions offering them include the University of Minnesota, Fairview Health Services and Hennepin County Medical Center. Argosy University and the Mayo School of Health Sciences are adding CLS programs. Winona State University, which has offered clinical laboratory technology for 40 years, is seeking CLS accreditation. Thirty-six hours of continuing education is required every three years.
