Medical Laboratory Science

Medical laboratory science professionals perform, interpret and assure the reliability of tests that are used in the detection, diagnosis, monitoring and effective treatment of disease. Seventy to 80 percent of all diagnostic decisions are based on the tests performed and the results provided by a medical laboratory scientist.

Medical Laboratory Science Classroom

SLU’s medical laboratory science program was one of the first in the country; it has more than 85 years of continuous accreditation.

Major in Medical Laboratory Science

Offered through the Doisy College of Health Sciences, Saint Louis University’s medical laboratory science program prepares you to take a national certification exam after graduation to become a certified laboratory professional. Our graduates’ pass rates are consistently at or near 100 percent, as is our graduate career placement rate.

Following two years of core courses in basic sciences and the liberal arts, and one year of pre-clinical laboratory-related coursework, you will enter the practicum phase of the curriculum in a clinical setting under supervision. Medical Laboratory Science students at SLU can pursue one of three tracks:

Seniors spend 20 weeks in practicum during either the summer or fall semesters at a variety of hospital laboratories in the St. Louis area.

You will have the opportunity to collaborate with faculty to develop and conduct a research project culminating in a formal scientific paper. Many of these projects have been presented at state and national professional conferences. Some have also earned student research awards or have been published.

In addition to University-level scholarships, sophomore, junior and senior medical laboratory science students are also eligible to apply for a scholarship from the Doisy College of Health Sciences Alumni Association, the Pope-Oller Scholarship and the Zipf-O'Rourke Research Scholarship.

Internships and Careers

Graduates with a medical laboratory science degree from SLU are qualified to work in all areas of the routine diagnostic lab including the five major areas of the laboratory: blood bank, chemistry, hematology, immunology and microbiology.

While most medical laboratory science graduates work in a clinical laboratory in the areas of diagnostic testing and laboratory management, some choose positions in research, forensic science and crime laboratories, laboratory equipment companies, or pharmaceutical and biotechnology industries. Many graduates choose to go directly to graduate, medical or professional schools.


SLU’s medical laboratory science faculty are certified laboratory scientists who are nationally recognized within their profession and dedicated to developing competent graduates who are responsive to the needs of society.
