Medical Laboratory Science, BS

Program Description

The Bachelor of Science in MLS degree prepares students to function as medical laboratory scientists in a wide variety of settings including hospital laboratories, clinics, research labs, physician office laboratories, public health laboratories and reference labs. The requirements the first 3 years include courses in biology, chemistry, math, social sciences, and humanities. The senior year includes advanced study in the MLS disciplines along with clinical practice in the clinical facilities.

Student Learning Outcomes

Students will:

  • Possess a broad understanding of science and its in-depth applications, techniques, principles, and instruments used to their specific option within the medical laboratory sciences major.
  • Demonstrate critical thinking skills
  • Practice the skills necessary to analyze and interpret test results through knowledge of physiological and pathological conditions that affect testing.

Admission to the MLS program is one time per year.  Students must complete an application to the MLS program and submit to the Program Director before May 30.  An interview may be requested.  Students should consult their Academic Advisor for additional information.

Medical Laboratory Science Certification

The medical laboratory scientist holds a key position in life-and-death matters involving the diagnosis and treatment of patients. Therefore, the practice of medical laboratory science is regulated both from within the profession and, in some states, by law. In addition to the coursework for the baccalaureate degree, employment as a medical laboratory scientist requires professional certification. A student may obtain one of three certifications in medical laboratory science: generalist, clinical chemist, or medical microbiologist. Complete information (and an application for the certification examination in any area) may be obtained from the medical laboratory science director. To apply for certification, a student must earn a “C” or better in all CLSC courses; and an interview and reference letters also may be required.

Medical Laboratory Science at Texas A&M University-Corpus Christi is approved through the National Accrediting Agency for Clinical Laboratory Science (NAACLS).

General Requirements

The Bachelor of Science in Medical Laboratory Science degree requires a minimum of 120 semester hours: 42 are from designated Core Curriculum Program courses, 20 are from medical laboratory core courses, 12-14 are required Foundation courses and 44 are Clinical courses. After their sophomore year (60 semester hours), students must have (and maintain) a cumulative GPA of 2.70 or above in their course work, with no course work older than 6 years. No “D” or “F” grades will be accepted as credit within the clinical laboratory core or clinical courses (see Notes).

Students entering with some college credit may not be required to take one or both of the First-Year Seminar courses (see The First Year Learning Communities Program for rules and exceptions concerning these courses). Clinical Laboratory Science students must take CLSC 4200 Professional Skills for Clinical Laboratory Scientists (2 sch) whether or not they have taken none, one or both First Year Seminars. 


The 3 hours of lecture is included in the University Core of the Math Foundations area, and the 1 hour of lab is included in the Component Area Option.


Admission to these courses is limited to students who have a minimum GPA of 2.7, and who have a “C” or better in all prerequisite Biology, Chemistry, and Biomedical Sciences courses. Full-time students will be given preference for admission to these courses.


  1. If a student earns a grade of D, F or W in a CLSC course, that course must be repeated. A course in which a grade of less than C (i.e., D, F or W-withdrawal) was earned may be repeated only once.
  2. A student who has earned a grade of less than C (i.e., D, F or W-withdrawal) in two CLSC courses or who has earned a grade of less than C (D, F or W-withdrawal) twice in the same CLSC course will be dismissed from the CLSC program.
  3. Students receiving a grade of D, F or W (withdrawal) or I (Incomplete) in a CLSC course may not progress to courses for which that course is a pre-requisite.
  4. Following dismissal, students may apply for reinstatement to the CLSC program. Reinstatement is competitive and is based upon space availability.
  5. In order for students to progress through the program, they must be in compliance with immunizations and hospital orientation regulations.
