Medical Laboratory Sciences

Medical laboratory sciences, also known as clinical laboratory sciences, is the allied health profession that directly impacts quality patient care.  Using cutting-edge technologies, medical laboratory scientists (MLS) analyze blood and other body fluids to help identify, treat, and prevent hundreds of diseases and conditions - from thyroid problems to diabetes, from leukemia to hepatitis.  Although most entry-level MLS practitioners are employed in hospital laboratories others obtain positions in areas such as: specialty clinics, reference laboratories, veterinary laboratories, biotechnology laboratories, public health laboratories, as well as in facilities that perform paternity testing or evaluation of compatibility for transplant patients.  Their skill set, emphasis on accuracy and precision in performing testing and knowledge of method development and validation are readily transferable.  This is one reason MLS graduates are also employed in the biomedical/biotechnology industry and research laboratories.

Master of Science Medical Laboratory Science Program Policies

Advancement to the Second Year

A student must have no grade lower than a C in required science and medical laboratory science (clinical laboratory science) courses to begin the second year and clinical practicums.  In addition a MLS student must file an Intent to Enroll in Clinical Practicum form, available from the program director at the end of the semester before practicums begin.  Students who are ready for clinical practicums are placed based on availability of positions at the affiliate sites throughout South Texas.  All students are expected to complete at least one clinical practicum at an affiliate located outside of San Antonio.  In the unlikely event that there are not enough sites available for the number of students ready to enter clinical practicums, assignments will be made according to program policies.  Students who must remediate a practicum will be assigned to an affiliate on a space-available basis.

Advisement and Schedule Planning

Applicants are encouraged to seek advisement from their college counselors or the School of Health Professions Office of Admissions and Special Programs at (866) 802-6288 (toll-free) or (210) 567-6220.  Students who complete program requirement courses at another college or university are urged to seek advisement about coursework that will fulfill the program requirements well in advance of applying to the Health Science Center.  Students must be advised each semester before permission is given to enroll in professional courses.  For students in the MS in MLS program, sequencing and completion of specific courses are very important.


Students who successfully complete the MS in MLS program are eligible to take the National Certification Examination for Medical Laboratory Scientist, MLS(ASCP) given by the Board of Certification (BOC) of the American Society for Clinical Pathology (ASCP).  Awarding of the degree is not contingent on passing an external certification or licensing examination.

Practicum Assignments

Clinical practicum assignments provide the student with the breadth of experiences that encompass all major content areas and exposure to laboratory technology.  Assignment to clinical affiliates for practicum courses is a random process that is based on availability of positions at the affiliate sites.  Practicum courses typically begin in the fall semester of the second year and are completed during the following summer semester.

All students are expected to complete at least one practicum at an affiliate located outside of San Antonio.  If a student declines to go to an assigned affiliate, this will result in a loss of the students' practicum position and possible delay of graduation.  Students who have special needs and request special considerations for practicum assignments must put the request in writing to the program director at least one semester before the practicum begins.  The program director will take the request to the faculty who will approve or disapprove the request.

Program Costs

In addition to required tuition and fees, there are costs for textbooks, scrubs, and equipment.  Detailed information about program costs can be found on the Master of Science in Medical Laboratory Sciences program website.

Transfer of Credits

Agreements for transferable coursework exist with some area colleges and universities.  Students should contact the program director of the Health Science Center's Clinical Laboratory Sciences Programs or the biology advisor at their institution to determine if such an agreement exits with their school.

For additional information, see the policies and procedures in the School of Health Professions section of this Catalog.
